2 Postal Addressing Standards

21 General

211 Standardized Delivery Address Line and Last Line

The Delivery Address Line and the Last Line of addresses output to the mailpiece should be complete, standardized, and validated with the ZIP+4 File and City State File, respectively.

It is recommended that delivery address information be stored in a minimum of 30 bytes or spaces in your computer system. The optimum recommendation is 64 bytes or spaces to be compatible with the Postal Service National ZIP+4 database.

The Postal Service defines a complete address as one that has all the address elements necessary to allow an exact match with the current Postal Service ZIP+4 and City State Files to obtain the finest level of ZIP+4 and delivery point codes for the delivery address. A complete address may be required on mail at some automation rates. See DMM A010 for more detailed information.

A standardized address is one that is fully spelled out, abbreviated by using the Postal Service standard abbreviations (shown in this publication) or as shown in the current Postal Service ZIP+4 File.

Example of standardized address, with recipient line, delivery address line, and last line.

212 Format

Format all lines of the address with a uniform left margin. Uppercase letters are preferred on all lines of the address block.

Example of correct address formatting

Lowercase letters in various type styles are acceptable provided they meet postal guidelines for OCR readability. Chapter 4 of Publication 25 provides complete guidelines for OCR readability that should be met when preparing a standardized mailpiece. Section C800 of the DMM contains OCR readability requirements that must be met for automation rates (other rates may also apply).

213 Secondary Address Unit Designators

Secondary address unit designators, such as APARTMENT or SUITE, are preferred to be printed on the mailpiece for address locations containing secondary unit designators. The preferred location is at the end of the Delivery Address Line. The pound sign (#) should not be used as a secondary unit designator if the correct designation, such as APT or STE, is known or is shown in the ZIP+4 File.
Examples  of secondary unit designators

213.1 Common Designators

The most common unit designators are:

APARTMENT APT
BUILDING BLDG
FLOOR FL
SUITE STE
UNIT UNIT
ROOM RM
DEPARTMENT DEPT
Note: See Appendix C.2 for approved designators.

213.2 Pound Sign (#)

If the pound sign (#) is used, there must be a space between the pound sign and the secondary number.
Example of pound sign usage

213.3 Alternate Location

If all Delivery Address Line information cannot be continued in the Delivery Address Line above the city, state, and ZIP Code, place secondary address information on the line immediately above the Delivery Address Line.
Example of alternate location usage

214 Attention Line

The Attention Line is placed above the Recipient Line, that is, above the name of the firm to which the mailpiece is directed.

Examples of attention line usage

215 Dual Addresses

Eliminate dual addresses on the output mailpiece, if possible, although mailer files may maintain both mailing and physical addresses. However, if dual addresses are used, place the intended delivery address on the line immediately above the city, state, and ZIP+4 code. This normally is the Post Office Box address. The other address must be placed on a separate line above the Delivery Address Line. The ZIP+4 code used must be the correct code for the delivery address on the line directly above the city, state, and ZIP Code.

Example of dual address usage

22 Last Line of the Address

221 City Names

It is strongly recommended that addresses use only approved Last Line (city) names as described in the Postal Service City State File currently in effect.

City names with the City State Mailing Name indicator flag set to YES in the City State File are considered part of a complete and standardized address; city names with the flag set to NO in the City State File should not be used in a complete and standardized address. For a complete and standardized address, abbreviations for city or state names must be shown in the Postal Service City State File. If you are preparing prebarcoded mail, city names set to NO for mailing name can be used.

222 Punctuation

With the exception of the hyphen in the ZIP+4 code, punctuation may be omitted in the delivery address block.

Examples of acceptable and preferred punctuation usage

223 Spelling of City Names

Spell city names in their entirety. When abbreviations must be used due to labelling constraints, use only the approved 13-character abbreviations provided in the City State File.

Note: Normally, the abbreviations follow the logic of using existing abbreviations, such as for suffix or directional words.

Examples of acceptable and preferred spelling of city names

224 Format

Format the Last Line with at least one space between the city name, two-character state abbreviation, and ZIP+4 code.

Example showing preferred format for lastline

Note: Two spaces are preferred between the state abbreviation and ZIP+4 code.

225 Military Addresses

225.1 Overseas Locations

Overseas military addresses must contain the APO or FPO designation along with a two-character "state" abbreviation of AE, AP, or AA and the ZIP Code or ZIP+4 code.

Examples of overseas military location addresses

AE is used for armed forces in Europe, the Middle East, Africa, and Canada; AP is for the Pacific; and AA is the Americas excluding Canada.

225.2 Domestic Locations

Use only the approved city name as listed in the City State File, along with the two-character state abbreviation and the ZIP Code or ZIP+4 code.

Example of domestic military location address

226 Preprinted Delivery Point Barcodes

The preprinted Delivery Point barcode must be correct for the delivery address, city, state, and ZIP+4 code that appear on the mailpiece.

· See Publication 25, Designing Business Letter Mail, Chapter 5.

· See DMM A800 and C840 for the barcode requirements that must be met to qualify for automation rates.

· For a list of vendors certified for various barcoding products, please visit our Website at www.usps.gov or call 1-800-238-3150.

23 Delivery Address Line

231 Components

The Delivery Address Line, as matched against the ZIP+4 File, must be broken down into its individual components on the mailpiece with one space between address elements.

These components are the primary address number, predirectional, street name, suffix, postdirectional, secondary address indentifier, and secondary address range.

The Postal Service uses the parsing logic below to enter address information into the files. When parsing the Delivery Address Line into the individual components, start from the right-most element of the address and work toward the left. Place each element in the appropriate field until all address components are isolated. This process facilitates matching files with AIS products and produces the correct format for output to a mailpiece.

Note: Mailers may use any parsing logic to achieve the same result.

Delivery address line examples

232 Street Name

Information found in the primary name field of the ZIP+4 File is used as the street name. The ZIP+4 File indicates the preferred primary street name to ensure that the correctly designated primary street record is matched during the address standardization processes.

Punctuation is normally limited to periods, slashes, and hyphens:

· Periods: 39.2 RD

· Slashes (fractional addresses): 101 1/2 MAIN ST

· Hyphens (hyphenated addresses): 289-01 MONTGOMERY AVE

Acceptable and preferred formats for street names

Note: Hyphens in the address range are significant and are not removed. Hyphens in the street or city name, however, normally are not significant and may be replaced with a space.

233 Directionals

This is a term the Postal Service uses to refer to the part of the address that gives directional information for delivery (i.e., N, S, E, W, NE, NW, SE, SW).

233.1 Abbreviations

Abbreviate directionals (if they are one of the eight standard directionals listed in AIS files) to the appropriate one- or two-character abbreviation.

Examples of directional abbreviations

233.2 Single Directionals

233.21 Predirectional Field

When parsing the address from right to left, if a directional word is found as the first word in the street name and there is no other directional to the left of it, abbreviate it and locate it in the predirectional field of the ZIP+4 File for standardization purposes.

Examples of acceptable and preferred usage of directional as first word in street name

233.22 Postdirectional Field

When parsing from right to left, if a directional word is located to the right of the street name and suffix, abbreviate it and locate it in the postdirectional field.

Examples of acceptable and preferred usage when directional is to right of street name

233.23 Two Directionals

When two directional words appear consecutively as one or two words, before the street name or following the street name or suffix, then the two words become either the pre- or the postdirectionals. Exceptions are any combinations of NORTH-SOUTH or EAST-WEST as consecutive words. In these cases the second directional becomes part of the primary name and is spelled out completely in the primary name field.

Examples of acceptable and preferred usage of multiple directionals

The other exception is when the local address information unit has determined that one of the directional letters is used as an alphabet indicator and not as a directional.

Example of acceptable, preferred, and unacceptable usage of multiple directionals

Note: In this example, the two-word directional is the primary street name.

Example of acceptable and preferred usage of multiple directionals as primary street name

233.3 Directional as Part of Street Name

When parsing from right to left, if the directional word appears between the street name and the suffix, then it appears as part of the primary name spelled out in the ZIP+4 File and is spelled out on the mailpiece.

Example of acceptable and preferred usage of directional as part of street name

The exception is when the local AIS unit has determined that the letters (E, N, S, or W) are used as alphabet indicators and not as directionals.

Examples of letters not used as directionals

234 Suffixes

234.1 Abbreviations

The suffix of the address should conform with the standard suffix abbreviations listed in the ZIP+4 File (see Appendix C).

234.2 Two Suffixes

If an address has two consecutive words that appear on the suffix table (Appendix C), abbreviate the second of the two words according to the suffix table and place it in the suffix field. The first of the two words is part of the primary name. Spell it out on the mailpiece in its entirety after the street name.

Examples of acceptable and preferred usage of two suffixes

235 Numeric Street Names

Numeric street names, for example, 7TH ST or SEVENTH ST, should be output on the mailpiece exactly as they appear in the ZIP+4 File.

Spell out numeric street names only when there are duplicate street names within a postal delivery area and the only distinguishing factor is that the one you matched is spelled out.

236 Corner Addresses

Corner addresses are replaced by physical street addresses in all AIS files.

Examples of acceptable and preferred usage of corner addresses

237 Highways

The following are recommended standardized examples of county, state, and local highways (see Appendix F for an expanded table).

Address Name
101 COUNTY ROAD 20
11216 COUNTY HIGHWAY 140
1501 HIGHWAY 50
220 INTERSTATE 680
22604 ROAD 123
1650 STATE HIGHWAY 335
7777 STATE ROUTE 39
1155 US HIGHWAY 70
3000 TOWNSHIP ROAD 20

238 Military Addresses

238.1 Overseas Locations

The Delivery Address Line for all APO/FPO military mail must be standardized as follows:

Example of typical delivery address line content for overseas locations

Examples of delivery address line content for overseas locations

Complete address examples for overseas locations

238.2 Domestic Locations

All domestic military mail must have a conventional street style address (see section 231).

24 Rural Route Addresses

241 Format

Print rural route addresses on mailpieces as: RR N BOX NN. Do not use the words RURAL, NUMBER, NO., or the pound sign (#).

Rural route address formatting

242 Leading Zero

A leading zero before the rural route number is not necessary.

Acceptable and preferred usage of leading zeros in rural route numbers

243 Hyphens

Print hyphens as part of the box number only when they are part of the address in the ZIP+4 File.

Use of hyphens in rural route box numbers

244 Designations RFD and RD

Change the designations RFD and RD (as a meaning for rural or rural free delivery) to RR.

Incorrect and correct designations for RFD and RD addresses

245 Additional Designations

There should be no additional designations, such as town or street names, on the Delivery Address Line of rural route addresses. Because street names used together with route and box numbers can create potential matching difficulty, mailers are encouraged to use only one style of addressing. If secondary name information is used, however, place it above the Delivery Address Line.

Incorrect and correct usage of additional designations for rural routes

246 ZIP+4

When applying a ZIP+4 code to a rural address, an exact match is preferred. If a box number is included in the address, the mailpiece must bear the appropriate ZIP+4 code representing the range for that box number. When box number information is not available, the Rural Route base record must be used.

25 Highway Contract Route Addresses

251 Format

Print highway contract route addresses on a mailpiece as: HC N BOX NN. Do not use the words HIGHWAY CONTRACT, ROUTE, NUMBER, NO., STAR ROUTE, or the pound sign (#).

Correct and incorrect formats for highway contract route addresses

252 Leading Zero

A leading zero before the highway contract route number is not needed.

Acceptable and preferred usage of leading zeros in highway contract route numbers

253 Hyphens

Print hyphens as part of the box number only when they are part of the address in the ZIP+4 File.

Usage of hyphens in highway contract route numbers

254 Star Route Designations

Change the designation STAR ROUTE, which usually refers to highway contract route, to HC.

Correct and incorrect designation of star routes

255 Additional Designations

There should be no additional designations, such as town or street names, on the Delivery Address Line of highway contract route addresses. Street names used together with route and box numbers can create potential matching difficulty. Mailers are encouraged to use only one style of addressing. If secondary name information is used, however, place it above the Delivery Address Line.

Correct and incorrect usage of additional designations for highway contract route numbers

256 ZIP+4

When applying a ZIP+4 code to a highway contract route address, an exact match is preferred. If a box number is included in the address, the mailpiece must bear the appropriate ZIP+4 code representing the range for that box number. When box number information is not available, the highway contract base record must be used.

26 General Delivery Addresses

261 Format

Use the words GENERAL DELIVERY, uppercase preferred, spelled out (no abbreviation), as the Delivery Address Line on the mailpiece. Each record will carry the -9999 add-on code.

Format for general delivery addresses

262 ZIP Code or ZIP+4

The ZIP Code or ZIP+4 code must be correctly applied for the general delivery record as found in the ZIP+4 File.

27 United States Postal Service Addresses

271 Format

Mail addressed to the United States Postal Service must contain a complete address.

Addresses may be located in the ZIP+4 File as street, firm, or Post Office Box records (record type S, F, or P, respectively). Most records carry the -9998 add-on code. However, many areas use different add-on codes.

Examples of formatting for United States Postal Service addresses

272 ZIP Code or ZIP+4

The ZIP Code or ZIP+4 code must be correctly applied for the United States Postal Service record as found in the ZIP+4 File.

28 Post Office Box Addresses

281 Format

Post Office Box addresses are output as PO BOX NN on the mailpiece.

Example formatting for post office box addresses

282 Leading Zero

Post Office Box numbers that are preceded by significant leading zeroes are identified in the ZIP+4 File by a hyphen (-) preceding the box number. Convert the hyphen into a zero on the output mailpiece.

Examples of leading zero usage for post office box addresses

283 Designations

PO Box addresses often appear with the word CALLER, FIRM CALLER, BIN, LOCKBOX, or DRAWER. Change these to PO BOX as output on a mailpiece.

Correct and incorrect designation usage in post office box addresses

284 Private Mailbox Addresses

Private companies may uniquely identify, by number, individuals or offices within their company for the purpose of simplifying their internal mail distribution. Print this number, called a MailStop Code (MSC), above the Recipient Line or the Attention Line. The words POST OFFICE BOX or PO BOX and the private mailbox number cannot be used on the Delivery Address Line. Only the Postal Service is entitled to provide delivery to a PO Box.

Example formats of private mailbox addresses

The Delivery Address Line is the standardized address of the private company.

Private companies offering mailbox rental services to individuals and businesses are considered commercial mail receiving agencies (CMRA). Addresses on mail received at a CMRA must adhere to specific requirements in the use of their private mailbox number (PMB). Mail sent to an addressee at a CMRA must include either the PMB identifier or the #, followed by the appropriate private mailbox number. Use of any other identifier is prohibited. Either a three line or four line address format can be used with a CMRA address and the PMB or # identifier, with the exception noted below. Where the CMRA's physical address requires its own secondary address element, the PMB or # address must follow the specific format rules stated below. It is not permissable to combine the secondary address element of the mailing address for the CMRA and the CMRA customer's private box number.

Examples:

Example formats of CMRA mailbox addresses

Example formats of CMRA mailbox addresses

Exception:

When the CMRA mailing address contains a secondary address element (e.g. rural route box number, suite, # or other term), the CMRA customer must use PMB when utilizing a three line address format:

Examples:

Examples of CMRA addresses

UNACCEPTABLE

The word CALLE is commonly placed before the street name and number. CALLE means STREET in Spanish, and placing the word CALLE prior to other address components is proper utilization based on Spanish composition. In addition to the word CALLE, the word AVENIDA or its abbreviation AVE may also appear in this position.

292 Urbanization

Urbanization denotes an area, sector, or development within a geographic area. In addition to being a descriptive word, it precedes the name of the area. This URB descriptor, commonly used in urban areas of Puerto Rico, is an important part of the addressing format, as it describes the location of a given street.

Example of urbanization descriptor

293 Common Translations

The following is a list of commonly used phrases that may appear in Puerto Rico addresses:

Spanish English
Apartado PO Box
Buzon Box
Buzon Rural Rural Box
Ruta Rural Rural Route
Ruta Estrella Highway Contract
Edificio Building

Examples of proper Spanish and English formats

The following is a list of Spanish words and their corresponding abbreviations:

Spanish Word Abbreviation Spanish Word Abbreviation

Caserio CAS Quebrada QBDA
Condominio COND Reparto REPTO
Cooperativa COOP Residencial RES
Corporacion CORP Sector SEC
Departamento DEPT Terraza TERR
Edificio EDIF Urbanization URB
Entrega General GEN DEL Villa VIL

294 Spanish Directionals

Directionals are not commonly used in Puerto Rico addresses because other descriptions, such as urbanization, identify geographic areas. When they do appear in addresses, however, they may appear as follows:

Spanish English
Directional Abbreviation Directional Abbreviation
Norte N North N
Noreste NE Northeast NE
Noroeste NO Northwest NW
Sur S South S
Sureste SE Southeast SE
Suroeste SO Southwest SW
Este E East E
Oeste O West W
Note: The only discrepancies between English and Spanish abbreviations occur in West directionals. In the ZIP+4 File, the English equivalents are used.

295 Delivery Address Line

295.1 General

The components of the Delivery Address Line are the primary address number, street name, secondary address identifier, and secondary address range.

Example components of the delivery address line

Note: In Puerto Rico there are usually no directionals or suffixes. Additionally, most apartment buildings do not have a street address. In this situation, the building name is part of the primary address identifier. If directionals are present in an address, they are part of the street name. Do not translate to directionals.

Examples of directionals

295.2 Street Names

Do not abbreviate street names if at all possible. Consult the abbreviation tables prior to making any abbreviation. For matching purposes, eliminating the word CALLE from named streets is recommended. Always print CALLE, AVENIDA, etc. on the mailpiece.

Incorrect and correct examples of street names

295.3 Numbered Streets

Numbered streets must always contain the word CALLE. This avoids misinterpretation of the delivery information between numbered streets and house numbers.

Incorrect and correct formats for numbered streets

Note: Do not translate CALLE to the suffix ST. This translation makes the address undeliverable.

295.4 House Numbers

House numbers may have fractional or alphabetic modifiers. To make an address more deliverable because of alphanumeric ranges, place the house number before the street name.

Incorrect and correct format for house numbers

Due to the amount of numbers within a block and a house number in Puerto Rico addresses, many identifiers are used to separate address elements, including BLOQUE, NUM, NO, CASA, and LOTE. None of the identifiers are part of the address, and they are not in the AIS files.

Certain rules have to be established to eliminate these identifiers from address files. Placing the house number before the street name is recommended.

When placing alphanumeric house numbers prior to the street name, avoid using hyphens.

Incorrect and correct usage of hyphens in alphanumeric house numbers

However, hyphens in the address range may be significant. When addresses contain up to three-digit numeric block numbers, it is necessary to include a hyphen.

Incorrect and correct formats for addresses with numeric block numbers

This process facilitates matching customer files against AIS since hyphens are present in the AIS files.

295.5 Urbanization

Because urbanizations are the most important part of the address, they are abbreviated to URB followed by the urbanization name.

Incorrect and correct format for urbanization name

Urbanizations are not repeated within five-digit zones and in most cases are served by one single carrier route. Therefore, a list of urbanization names serves for Five-Digit ZIP Code verification.

Note: Certain urbanizations are known as extensiones, mansiones, repartos, villas, parques, and jardines. When these names are present, there is no need to place the abbreviation URB prior to the name of the urbanization.

Urbanization name examples

Note: Some areas in Puerto Rico served in urbanizations do not have a street name. The urbanization becomes a street name and is located in the primary identifier of the AIS files.

295.6 Post Office Box

Print Post Office Box addresses as PO BOX on the mailpiece.

Example of correct format for post office box address

PO Box addresses often appear with the words CALLER, CALL BOX, GPO BOX, PO BOX S-1190, APTDO, APARTADO, BOX, BUZON. These are changed to PO BOX as output to a mailpiece.

Incorrect and correct format for post office box addresses

In certain areas, the station name appears in the line above the city, state, and ZIP Code. We recommend that it is either eliminated from the output address or relocated, placing PO BOX above the city and state and placing the station name on the line above. Station names are not present on the ZIP+4 File.

Incorrect and correct placement of station name

295.7 Rural Route

Rural route addresses are output on a mailpiece as RR N BOX NN. Do not use the words RURAL, RUTA RURAL, BUZON, or BZN.

Example of rural route address

A leading zero before the rural route number is not necessary.

Incorrect and correct use of a leading zero before rural route number

The designations RFD, RD, and RT (meaning rural route) are changed to RR.

Incorrect and correct usage of rural route designation

There should be no additional designations, such as sector names, on the Delivery Address Line of rural addresses. Sector names used together with route and box numbers can create potential matching difficulty. Mailers are encouraged to use only one style of addressing. Eliminate this information in Puerto Rico addresses.

Incorrect and correct usage of sector names in rural route addresses
