Informal and comprehensive human-readable definition of a concept. Description	This category encompasses data quality rules that verify postal codes follow the correct syntactic format for their country. Each country has specific formatting rules for postal codes including fixed or variable lengths, allowed characters (numeric, alphanumeric, or mixed), and structural patterns (with or without spaces or hyphens). For example, US ZIP codes are 5 or 9 digits, UK postcodes follow a specific alphanumeric pattern, and German postal codes are exactly 5 digits. Format validation checks these country-specific requirements to ensure postal codes are syntactically correct. This is essential for address validation, mail delivery, and geographic data processing. The validation supports the Representational_consistency dimension by ensuring postal codes adhere to nationally defined formatting standards.

Postal codes were introduced there in 2011 and are managed by Afghan Post, the national public postal service under the direction of the Afghan Ministry of Communications and Information Technology. An Afghan postal code has four digits: the first two, ranging from 10 to 43, correspond to the province, while the last two correspond either to the city or delivery zone, in the range 01 to 50, or to the district or delivery zone, in the range 51 to 99.

Post code format invalid (Argentina) REPRESENTATIONAL_CONSISTENCY	AR (Argentina)	This rule checks the post code format of Argentina. The Argentine postal code, the CPA or Código Postal Argentino, changed in 1999 from a block of four digits to a block of eight characters made up of one letter, four digits and three letters. The first character cannot be I, O or V. The first five characters form the prefix and the last three the suffix. The codes cover groups of buildings, either odd- and even-numbered by street or by block, and therefore a much finer area than the earlier code. The four digits in the new code are usually the same as the pre-1999 four-digit code, although some were changed to allow improved zoning. The letter at the start of the prefix indicates the province, and the suffix identifies the group of buildings within the zone indicated by the prefix. In the earlier four-digit code the first two digits indicated a postal district and the last two a post office, and the code could not start with a zero.	INFO	RELEASED(2020-01-01)

The postal code, the Postleitzahl, is written on the same line as the name of the town and before it. Austrian postal codes consist of a block of four digits and the first digit cannot be a zero.

Post code format invalid (Costa Rica) REPRESENTATIONAL_CONSISTENCY	CR (Costa Rica)	This rule checks the post code format of Costa Rica, which changed its postal code system in March 2007 from four digits to either five digits or five digits followed by a hyphen and four more. The five-digit form is used for street addresses and the longer form for post office box addresses.

Post code format invalid (Ghana) REPRESENTATIONAL_CONSISTENCY	GH (Ghana)	This rule checks the post code format of Ghana. On 18 October 2017 Ghana Post introduced a digital address system called GhanaPostGPS as an alternative to the traditional address system. It divides the country into squares of five by five metres and gives each square a code. Although billed as providing a unique address for every property, the system duplicates addresses that share the same square in the grid. At present creating a code requires the user to have mobile communications, an app and to be standing at the property, and anyone trying to find an address likewise needs mobile communications, an app and the code, while the codes are not yet fully accurate because of fluctuations in GPS quality. The codes consist of two letters, or a letter and a digit, followed by an optional hyphen, three digits, another optional hyphen and four further digits.	ERROR	RELEASED(2024-04-16)

Post code format invalid (Portugal) REPRESENTATIONAL_CONSISTENCY	PT (Portugal)	This rule checks the post code format of Portugal, whose postal service C.T.T. changed the system in 1999 and 2000. The old code, the Código Postal, consisted of four digits beginning with a number between 1 and 9 and was always followed on the last line of the address by the town name in upper case. In 1999 three further digits were added to identify smaller areas such as streets, blocks, districts, small settlements or groups of small settlements, or large users within these districts, so that four-digit and seven-digit codes are both likely to be found during a transition period. In the new code the seven digits are written as four digits, a hyphen and three digits, and the first four digits correspond to the old postal code. Where the fourth digit is 0 or 5, the code is usually that of a central distribution point. While the four-digit code was in use, large users were indicated by the word CODEX after the name of the town, now that the seven-digit code applies, CODEX should no longer appear in addresses.

Each six-digit code, the Postal Address Code or Poštanski adresni kod (PAK), covers a small group of buildings or a single company: the first two digits cover a region of one or several municipalities, the next two define the delivery zone and the final two indicate the street, part of a street, building or company.
