United States ZIP codes are five numerical digits long. ZIP+4 codes, also known as add-on or plus-four codes, include four additional digits that identify a geographic segment within a ZIP code delivery area.
The last four digits are not specific to a city but to a street address or Post Office Box. This is what an address looks like with the ZIP +4 Code: The first five digits identify the area of the country and the delivery office to which the mail is directed. ZIP Codes start with a zero (0) in the northeast and gradually get higher as you move west.

How to Read a ZIP Code
- Following the assignment of the first number in a ZIP Code, the United States Postal Service (USPS) assigns the next two digits based on the location of the city.
- If an area has a major town or city, the United States Postal Service (USPS) would frequently award it the first ZIP Codes.
- Following that, the ZIP Codes will be shown in alphabetical order.
- The first three digits of a ZIP Code, when added together, often indicate the sectional center facility to which that ZIP Code belongs, according to most sources.
- This facility serves as the mail sorting and distribution hub for a certain zone or geographic area or region.
- Some divisional center facilities have numerous three-digit codes given to them, which makes it difficult to locate them.
For example, the Northern Virginia sectional center facility in Merrifield is issued ZIP Codes that begin with the numbers 220, 221, 222, and 223 to distinguish it from other similar facilities.The fourth and fifth digits of the ZIP Code show the geographical location of the city or municipality.For example, if a letter is received with a ZIP Code of 47722, the United States Postal Service (USPS) can determine that it is in Indiana (4), Vanderburgh county (77), and the region around the University of Evansville (22)
ZIP Codes are Lines, Not Shapes
- ZIP Codes are not assigned based on geographic boundaries such as state borders. In truth, because ZIP Codes are intended only for the purpose of increasing postal efficiency, they may and do transcend county and state lines. As an illustration: 42223 encompasses Christian County, Kentucky, and Montgomery County, Tennessee
- 97635 contains sections of Lake County, Oregon, and Modoc County, California
- 51023 and 51001 are located in both Iowa and Nebraska
- and 42223 spans Christian County, Kentucky, and Montgomery County, Tennessee.
- ZIP Codes do not represent physical areas; instead, they identify address groupings or delivery routes.
- Although most ZIP Codes may be loosely allocated to a geographic location, ZIP Codes do not represent geographic regions.
- As a result, ZIP Code ″areas″ might overlap with one another, be included within another ZIP Code, or have no geographical boundaries at all.
- For example, ZIP Codes that begin with 095 are issued to the Navy and do not correspond to a specific geographic place as a result.
- Similarly, ZIP Codes are not allocated to locations that do not have regular postal routes (rural route regions) or areas that do not get mail delivery (undeveloped areas).
- Because they are based on few delivery routes, the boundary between ZIP Code zones is indeterminate in certain places.
See our guidelines on how to locate a county by ZIP Code for further information.Whenever a ZIP Code crosses across a county boundary, Smarty (previously SmartyStreets) displays the default county in the line called ‘County Name’ and includes an additional line named ‘Alternate Counties’ in the table.
- The United States Postal Service (USPS) modified its ZIP Code system in 1983 to incorporate the new ZIP+4.
- A ZIP+4 Code is made up of the original five-digit code plus four more digits, resulting in a complete nine-digit postal code.
- With the whole ZIP Code, you may identify any tiny delivery segment, such as a street, a city block, a group of flats, or even a single address, which gets a large amount of mail.
- Using a ZIP+4 Code is not essential, as it is often computed automatically during the sorting and processing of the mail.
- ZIP+4 Codes are formatted as follows: As a general rule, each Post Office Box is assigned a unique ZIP+4 code.
- With a +4 on the ZIP Code, the last four digits of the box number are frequently used, as is zero plus the final three digits of the box number, or if the box number is less than four digit, zeros followed by the box number.
Because of this variation, the ZIP+4 Code for each Post Office Box must be searched up individually.Not all USPS deliverable addresses have a ZIP+4 code allocated to them, despite the fact that the majority of them do.For some addresses, geocoding lookups or address validation that need a ZIP+4 may not be successful, depending on the address type.While the United States Postal Service may not be able to offer correct geocodes for such addresses, Smarty can still provide roof-top level geocodes for the majority of addresses in the United States.

How many number are in a ZIP code?
- The United States Postal Service (USPS) modified its ZIP Code system in 1983 to incorporate the new ZIP+4.
- For a full nine-digit ZIP Code, the basic five-digit code is supplemented with four additional digits.
- With the whole ZIP Code, you may identify any tiny delivery segment, such as a street, a city block, a group of flats, or even a single address, which gets a significant amount of mail.
- While a ZIP+4 Code is not necessary, it is often computed automatically during the sorting and processing of the mail.
- The following is how ZIP+4 codes look: A ZIP+4 code is assigned to each Post Office Box as a rule.
- With a +4 on the ZIP Code, the last four digits of the box number are frequently used, as is zero plus the last three digits of the box number, or if the box number is fewer than four digits, zeros followed by the box number.
Because of this variation, the ZIP+4 Code for each Post Office Box must be searched up separately.In certain cases, a ZIP+4 Code is not given to all USPS deliverable addresses.Geocoding lookups and address validation that need a ZIP+4 may not be successful for such addresses.Smarty can still offer roof-top level geocodes for most addresses in the United States, even if the USPS does not supply precise geocodes for such addresses.

ZIP Code Overview
The Importance Of ZIP Codes
- In the United States, ZIP code information is essential for conducting commercial activities.
- Whether you’re delivering mail, handling fraud detection, or studying demographic information, this is a vital parameter to know.
- The purpose of this article is to assist you in better understanding the background behind this combination of statistics in greater depth and detail, so that you may use this data point to your advantage in your company’s operations.
The American ZIP Code System (USPS)
- The ZIP code’s primary function is to expedite and streamline the processing of information.
- Processing delays may occur as a consequence of typographical errors in ZIP codes.
- The United States Postal Service is the ultimate source for gaining an in-depth grasp of the ZIP code encoding system.
- Hopefully, this extensive FAQ resource will be of use.
- What you’ll see is that every digit contained within a ZIP code has significance when considered as part of a systematic strategy.
ZIP & ZIP+4
- ZIP codes in the United States are composed of five number digits.
- In addition to being known as ZIP+4 codes, they are sometimes referred to as add-on or plus-four codes since they feature four additional digits that define a geographic section inside a ZIP code delivery region.
- The first number of a ZIP code denotes a specific set of states in the United States.
- Each of the group’s second and third numbers represents a territory, such as a significant city, inside that group.
- It is just necessary to know the first five digits of the ZIP code in order to send mail.
- Including the complete ZIP+4 code, on the other hand, can shorten delivery times owing to the particular geographic information being conveyed.
ZIP codes are converted into barcodes, which allow for the automatic sorting of mail, hence reducing the amount of human monitoring that is required in the process.
History Of The ZIP Code
- The ZIP code system was established during a period of economic boom in the United States of America.
- Due to a quick increase in population as well as a burgeoning in commercial activity following the first and second World Wars, it developed out of necessity.
- During this time period, existing postal delivery methods began to fail as a result of the requirement for information to move across the whole United States continent more quickly than previously.
- A new system was developed in response to this, and it was officially deployed in 1963 following a 20-year development process by Robert Moon, who spent his entire career working for the United States Postal Service (USPS).
- A specified numerical system was used instead of a less organized recall of well-known cities, counties, and states in order to operate this system.
- This transition from a more informal and personal method of managing mail to one that was more defined and ordered sparked criticism and a 20-year battle.
At the time of Moon’s death in 2001, he was credited with the development of the first three digits of the United States ZIP code.By 1967, ZIP codes were used to identify all mail delivered in the United States.This period in history saw the United States Postal Service responsible for transporting 80 billion pieces of mail, an increase from the previous peak of 30 billion during World War II.Meanwhile, a new world of transportation was emerging, characterized by the use of trucks and airplanes, which were capable of transporting commodities more effectively than traditional train systems.
As time went on, ZIP codes grew to serve a greater number of functions in American culture and society.When it comes to the United States Census, for example, ZIP codes are used to categorize demographic information, which includes but is not limited to educational attainment, family income, household size, and other population health indicators, among other things.ZIP codes are used by financial institutions such as banks, insurance providers, and credit card firms to determine interest rates.
Zip codes are also employed in online purchasing applications, particularly in the areas of fraud detection and prevention, as previously mentioned.ZIP codes are essential for knowing the demographic features of the United States as well as conducting business inside the country.
ZIP Codes In Global Perspective
It is a member country of the Universal Postal Union that the United States belongs to (UPU). In order to promote the free interchange of worldwide mail, the United Nations Postal Union (UPU) relies on postal code standards created and maintained by the United States of America.
The United Nations Regulatory Body
- The United Nations’ regulatory authority, the United Nations Population Fund (UPU), is reliant on member countries like the United States for funds, insights, and scientific leadership.
- Using Geographic Information Systems (GIS) technology from the United States, the Universal Postal Union has been able to construct new postal systems in developing countries from the ground up in recent years.
- A second function of the UPU is to act as a mediator in conflicts arising in a complicated global trade environment.
- The United States, with its ZIP code system and expertise, is one of the most generous donors to the United Nations Population Fund (UPU).
- Therefore, it is critical for technologists who deal with ZIP code data to realize that postal code systems have far-reaching geopolitical relevance as problem-solving tools, and that this understanding should be communicated to them.
Postal Codes In Canada (Canada Post)
- Funding, ideas, and scientific leadership are provided by member nations such as the United States to the United Nations’ regulatory body.
- Geographic Information Systems (GIS) technology from the United States has been leveraged by the United Nations Postal Organization (UPU) to establish new postal systems in poor countries from the ground up in recent years.
- In addition, the UPU serves as a mediator in a very complicated global trade environment, according to its mission statement.
- United States, with its ZIP code system and expertise, ranks among the leading funders of the United Nations Population Fund (UNFPA).
- Therefore, it is critical for engineers who deal with ZIP code data to recognize that postal code systems have far-reaching geopolitical relevance as problem-solving tools, and that this understanding should be shared with their colleagues.
Why Are There 3 and 4 Digit ZIP Codes in the United States?
- August 21st, 2012 When you view our ZIP Code Database in MICROSOFT EXCEL, you’ll see that the ZIP Code column contains 3 and 4 digit digits, respectively.
- ZIP Codes in the United States are always five digits in length.
- These three and four-digit integers are really preceded by one or two zeros.
- For example, when you see the number ″501″ for Holtsville, it is actually the number 00501.
- Excel, by default, transforms this column into a number and eliminates the leading zeros from the beginning.
- Fortunately, there is a quick and simple method of restoring what has been lost.
1.The first thing you should do is select the complete ZIP Code field and press Enter.This may be accomplished by selecting the letter ″A″ located above the text ″ZipCode.″ The column will change color to a light blue tint.2.
Select any location in the ZipCode column by using the right mouse button on your computer.Then select ″Format Cells″ from the drop-down menu.3.
Afterwards, choose ″Special″ from the ″Number″ column, and ensure that the ″Type″ field is set to ″Zip Code.″ 4.When you’re finished, click on ″OK″ at the bottom of the page.That’s all there is to it!Now that all of the leading zeros have been restored, the ZIP Code has been expanded to five digits.
Practical International Data Management – Postal codes
- Codes that are used inside postal addresses to designate a geographic location, point, or route, or to serve as a pointer to a corporation or building are known as postal codes.
- Used to facilitate mail sorting and delivery as well as to avoid misunderstanding when two streets with the same name exist within a single inhabited area.
- Note: A postal code is a general word that refers to a code that is included in a postal address to help in the sorting and delivery of mail.
- A variety of other words are employed by specific postal administrations.
- In terms of vocabulary, there are differences between languages (e.g., Postal Code, Code Postal, Código Postal, Kody pocztowe) as well as between languages (e.g., Postal Code, Postcode, ZIP Code, PIN Code, etc.)
Coverage. Postal codes can be used to refer to a variety of geographic locations, users, and postal addresses. A postal code may include the following areas:
For example, in certain nations, each postal code covers a same number of delivery sites of equal size and scope. In some cases, coverage is limited.
The extent of a region covered by a single geographic postal code might vary tremendously from one location to the next.
- In this image of Australia’s postal code limits, you can see the enormous size disparity across postal code districts. There are many outliers, even in nations whose postal code systems theoretically correspond to administrative district borders, due to inertia in one system while the other changes, or for pragmatic reasons, such as permitting better mail delivery to those regions affected.
- Examples include the following: In the United States of America, the ZIP Code may normally be used to determine state, although there are some exceptions. In the following examples: Fishers Island, New York, bears the ZIP Code 06390 and is served from Connecticut because the only ferry service is to Connecticut – all other New York ZIP codes (with the exception of those at Holtsville for the Internal Revenue Service (IRS)) begin with ″1″
- some Texas ZIP Codes are served from New Mexico (most notably some El Paso ZIP codes) and thus bear codes beginning with ″885″ (contiguous numerically with 870-884 NM) rather than 41048 Hebron, Kentucky The physical address of the airport is 2939 Terminal Drive Hebron, Kentucky In essence, the Kenton County Airport Board’s mail is sent to an Ohio ZIP code, while the airport’s actual location is in a Kentucky ZIP code.
Postal codes are available in a variety of lengths and forms all throughout the world. They may be numeric or alphanumeric in nature, and they may or may not include punctuation. They may now include upper case letters (A-Z, sans diacritical markings), numerals, and/or punctuation.
- Many nations and territories do not have a postal code system
- this is especially true in developing countries.
- Angola, Antigua and Barbuda, Aruba, Bahamas, Belize, Benin, Bolivia, Bonaire, Botswana, Bouvet Island, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Comoros, Congo (Brazaville), Congo (Kinshasa), Cook Islands, Curaçao, Djibouti, Dominica, East Timor, Equatorial Guinea, Eritrea, Gabon, Ghana
In certain countries, big users may have three separate postal codes: one for a geographic location, one for a post office box, and one for being a large user.
- An address block may legitimately include more than one postal code
- however, this is not always the case.
- Consider the following scenario: Serbia now employs both a 5-digit postal code and a 6-digit postal code in the same address:
The Global Sourcebook for International Data Management is the source of this information. In light of the time lag necessary to update and distribute postal code data files, in addition to the restriction that no data file is 100 percent accurate, new addresses may not appear in current postal code data files, and old postal code data files may contain addresses that are no longer valid.
- When it comes to postal codes, there is a distinction between them and sorting codes.
- A sorting code is a code that occurs after a place name to offer information that is not included in the postal code itself.
- 1000 Brussel X, for example, indicates that the 1000 is a postal code and the X is a sorting code that indicates the location of a certain post office within that region.
- In general, postal code systems physically span an entire nation, whereas sorting codes are only used for certain areas or locations, such as Dublin in the Republic of Ireland, or for specific addresses exclusively.
It is possible for a single building to have more than one postal code, especially if it is occupied by a significant number of big users.
- Postal codes may begin with one (or more) zeroes, depending on the country.
- Algeria, Armenia, Australia, Cambodia, Finland, France, Germany, Guatemala, Holy See, Italy, Laos, Maldives, Nepal, Puerto Rico, Romania, Slovakia, Spain, Ukraine, United States of America, United States Virgin Islands, are just a few of the countries and territories whose postal codes may begin with a zero (this is not an exhaustive list).
00011 ROMA, ITALY 340 Tiburtina Valeria Postal codes occur in a variety of locations inside an address block, depending on where you are in the world. Examples:
Postal codes can also be flagged as inappropriate by the obscenity screening system. As an example, V4G 1N4 Delta, British Columbia, Canada appears on a map.
- It is possible for a location to have postal codes from more than one nation.
- For example, because physical access to the German village of Büsingen and the Italian settlement of Campione d’Italia is more convenient through Switzerland, the Swiss Post Office has assigned the following postal codes to these two locations:
8238 BÜSINGEN (German postal code 78266) 6911 CAMPIONE D’ITALIA 8238 BÜSINGEN (German postal code 78266) (Italian postal code 22060) For example, Northern utilizes Cypriot postal numbers with four digits, but for mail coming from or going via Turkey, a Turkish postal code with six digits beginning with 922 is used.
- It is possible for a country or territory to lack its own postal code system, but to be assigned codes by another country
- for example, Hong Kong and Macao do not have their own postal code systems, but for mail from China, the postal codes 999077 and 999078 have been assigned to Hong Kong and Macao, respectively.
- For example, Liechtenstein is included in the Swiss postal area
- San Marino and the Holy See are included in the Italian postal area
- the Marshall Islands, Micronesia, and Palau are included in the United States of America postal area
- and the United Kingdom is included in the United Kingdom postal area.
- Please do not make ″postal code″ a mandatory field for nations and territories that do not utilize postal codes, or for countries and territories where postal codes are not extensively distributed and used. It is unlikely that all clients will be familiar with their postal code, or even that such a system exists in their nation.

- If you are aware of the nation in which the postal addresses are located, you can use a localised term for the postal code on customer-facing forms if the country is known. In all other cases, the general phrase postal code should be used. Customers with addresses in different countries should not be served using local forms, such as ZIP codes.

- Depending on the country, postal codes are produced in a variety of different methods.
- Make no distinction between a field, an input form, or processing that is tailored to only one country’s postal code format.
- To ensure that postal code fields are valid, allow them to contain alphabetic letters, numbers, and punctuation.
- Forcing the field contents to be in uppercase is necessary since there are no instances of postal codes written in lower-case characters at this time.
- Allow only alphabetic characters between A and Z to be used in postal codes
- no additional characters (for example, those with diacritical markings) are now permitted.

- You may get an updated version, as well as others that include more thorough information, by visiting this website.
- No postal codes should be attempted to be stored in a numeric field, even for nations that have postal codes with numeric digits.
- In several countries, the postal code may begin with a zero, which is removed when data is entered in numeric fields, causing the data to be corrupted.
- A firm or (in rarer cases) an individual can have up to three addresses: a street address, a postal address, and a large-user address.
- A street address is the most common type of address.
- It is possible that each of these has its own postal code, depending on the nation.
- If these postal codes are to be recorded in a single record, it is important to enable three fields to be designated for the storage of these postal codes.
Postal codes should be kept in a separate field from the rest of the address information. It is employed in a wide range of data processing applications.
Postal codes can be expressed in the following format: ″B-1000,″ where ″B″ is the country code. Due to the fact that this information duplicates the country code, which should be saved elsewhere in a database and may be updated on export if necessary, it can be removed before being stored or processed.
Postal codes occur in a variety of locations inside an address block, depending on where you are in the world. Make certain that it is output in the proper location to prevent customer aggravation and to encourage ideal delivery efficiency, since postal information is read and recognized by computers in many nations, including the United States.
This section of the Global Sourcebook for International Data Management, edited by Graham Rhind, contains information on the postal code and address systems of all nations that have them.

How Full ZIP Codes Are Used
- Knowing what the last four digits of a ZIP Code are all about necessitates a thorough understanding of what ZIP Codes are in general terms.
- The Zone Improvement Plan was developed by the United States Postal Service in order to make it simpler to send mail and parcels around the country.
- Due to the way mail was dispersed, it helped split the country into distinct ″zones,″ which aided in speeding up the sorting and delivery process.
- During the same time period that the Postal Service Department announced the Zone Improvement Plan on July 1, 1963, they also presented the world to Mr.
- ZIP ″Zippy,″ a fictional character created by the Postal Service.
- Zippy is the official ZIP Code mascot, and he can be found on our ZIP Codes 101 website as well.
They also produced the ZIP Code jingle, which goes as follows: The audio element cannot be played because your browser does not support it.Since 1963, as the population of the United States has grown and dispersed, it has become necessary to extend the system in order to accommodate everyone and their canine companion.That’s where the ″plus 4″ portion of the equation comes in.However, we’re getting ahead of ourselves, so let’s start with the fundamentals.
USPS Five-Digit ZIP Codes
- These are the codes with which you are already familiar.
- They have the following appearance……and are most usually used to denote a destination post office.
- The reason behind this is as follows: If you’re shipping a letter from Boston to Seattle, the Massachusetts postal carrier isn’t really concerned with the street address of the recipient’s residence.
- What you may label ″beyond his jurisdiction″ is the situation.
- He only has to know which postal carrier to use in order for the other carrier to deliver the package to the correct address.
- On any given day, a postal worker can only cover a certain amount of ground.
And because the United States Postal Service has a policy of delivering in all weather conditions, including rain, sleet, and snow, there is no way to provide the service of delivering in stages (some today, some tomorrow).In other words, each one post office can only service the area that it can reach in a single day.That is reflected in the ZIP Codes.The majority of the time, a ZIP Code is associated with a post office; that is, every one of the latter has a corresponding one of the former.
ZIP Codes may be thought of as a sort of postal address for a certain post office location.Some agents cover more than one ZIP code, but the majority of them operate on a one-on-one basis.Note that ZIP Codes are not ″boundaries,″ which is extremely essential to understand.
They’re a collection of delivery routes that have been compiled.They do not adhere to physical or administrative boundaries, and they are capable of crossing city, county, and even state boundaries.They travel in the same direction as the delivery vehicles.Some ZIP Codes are considered to be outliers.One type of ZIP Code is designated as ″military,″ and it includes anything from military sites (local and international) to battleships at sea.Then there are ZIP Codes that are ″unique.″ Because of the large volume of mail that businesses and organizations send and receive, they may be assigned their own ZIP Codes.
These organizations regularly take advantage of bulk mailing reductions because they typically have a mail department that (1) presorts mail before delivering it to the USPS and (2) distributes mail internally so that the USPS is not required to do so.″Military″ and ″unique″ ZIP Codes are similar to ordinary ZIP Codes in that they circumscribe their own delivery region.Visit our ZIP Codes page for a more in-depth look at the system.
ZIP Code + 4 Meaning
- ZIP+4 Numbers are four-digit codes that are attached to the end of the original five-digit United States Postal Service ZIP Codes.
- When mailing with the United States Postal Service, using complete ZIP Codes ensures the fastest and most accurate delivery possible.
- Once an address has been authenticated and shown to be legitimate, they are only made available for that address to be used.
- Each of these numbers corresponds to a distinct delivery route, which refers to the actual path that a postal truck would take in completing a single drop-off.
- Typically, this consists of 10 to twenty different residences or sites.
- PO Boxes are also allocated ZIP+4 codes in addition to their regular ZIP codes.
Typically, each PO Box is assigned a unique +4 Code, which is frequently the same as the box number.Because ZIP codes plus four additional digits are based on delivery routes rather than more permanent borders, the last four digits of a full ZIP Code can vary on a regular basis.ZIP codes plus four additional digits are based on delivery routes rather than more permanent boundaries.It is also possible that five-digit ZIP Codes will change, but this will happen seldom; it is far less probable that you will be residing in a ZIP Code when it changes.
This is not the case for the complete 9-digit ZIP Code.The +4 on a ZIP Code can be altered as frequently as once a month, depending on factors like as the number of postal employees on the job, who is assigned to which route, and other factors.
Benefits of Full ZIP+4 Codes

What is a Zip+4 Code and Why May It Change?
- ZIP+4 codes are utilized and allocated by the United States Postal Service (USPS) to help with routing and delivery of mail.
- The last four digits of your postal code are not necessary for delivery of your mail and may change on a regular basis.
- As a consequence of the Marathon County Uniform Addressing Program, there have been a number of +4 digit adjustments.
- When a new street or a new block range of addresses is added to the United States Postal Service data system, a new +4 number may be assigned.
- Marathon County does not assign this number; rather, it is assigned by the United States Postal Service.
- As an illustration: Mosinee, WI 54455-1234 -> 54455-6789 Mosinee, WI 54455-1234 -> 54455-6789 It is possible for a ZIP+4 code to refer to a geographic segment within the five-digit delivery area that is defined by the basic five-digit code plus four additional digits.
Examples of such segments include city blocks, groups of apartments, individuals who receive large amounts of mail or a post office box, or a specific delivery route — in which case the actual path that the mail truck would take may have changed.Given that ZIP codes are based on delivery routes rather than more permanent borders, the last four digits of a whole ZIP code can change on a regular basis.Five-digit ZIP codes are also subject to change, although only on a rare occasion.In the case of ZIP+4, this is not the case.
The +4 on a ZIP code can be altered as frequently as once a month, depending on factors like as the number of postal employees on the job, who is assigned to which route, and so on.A ZIP code is a postal code that was first used by the United States Postal Service (USPS) in 1963 as part of a system that was implemented nationwide.In 1983, the United States Postal Service established an expanded ZIP+4 code, which consists of the five digits of the ZIP code followed by a hyphen and four extra numbers that relate to a more particular location.
Initial efforts to promote general use of the new format, however, were greeted with widespread opposition, and the +4 code is no longer necessary.Mail is typically read by a multiline optical character reader (MLOCR), which almost instantly determines the correct ZIP+4 code from the address — as well as the even more specific delivery point — and sprays an Intelligent Mail barcode (IM) on the face of the mail piece that corresponds to 11 digits — nine for the ZIP+4 code and two for the delivery point — on the face of the mail piece.
