Informal and comprehensive human-readable definition of a concept. Description	This category encompasses data quality rules that verify business identifiers are syntactically correct according to their defined format specifications. For each identifier type (VAT numbers, company registration numbers, tax IDs, etc.), there are specific format rules regarding length, allowed characters, positional requirements, and structural patterns. The validation typically works on 'cleaned' identifiers where separators like hyphens, dots, and spaces are normalized. Format checks verify the number of digits, allowed character types at specific positions, and overall structural correctness. This is fundamental for data quality as incorrectly formatted identifiers cannot be processed by automated systems or validated against external sources. Format validation supports the Representational_consistency dimension by ensuring identifiers adhere to their technical specifications before further processing or validation.

Identifier Format invalid (Fiscal code (Italy)) REPRESENTATIONAL_CONSISTENCY	IT (Italy)	In Italy the tax number can take one of two forms: eleven digits for legal entities, which are the Italian European VAT identifier without its IT prefix, or sixteen alphanumeric characters for freelancers and natural persons. The sixteen-character form is known as the Codice Fiscale and follows a fixed structure. The first three characters are letters derived from the last name and the next three are letters derived from the first name. Positions seven and eight are digits for the year of birth, position nine is a letter for the month of birth, and positions ten and eleven are digits encoding the day of birth and the sex. Positions twelve to fifteen are one letter followed by three digits identifying the Italian town or the foreign country of birth, and the sixteenth character is a checksum character that serves a supervisory function.

Since no publicly available official source could be found confirming that Jordanian GST and tax identifiers must always have exactly seven digits, the accepted format was extended to allow seven to nine digits. The earlier seven-digit validation rested on secondary VAT and GST reference sources, whereas the value 17909465 is an eight-digit numeric tax number and should therefore not be rejected merely because it does not match the historical seven-digit assumption.

Identifier format invalid (REA number (Italy)) REPRESENTATIONAL_CONSISTENCY	IT (Italy)	This rule reports values held as REA number (Italy) whose format is not a valid Chamber of Commerce entry reference. The REA number identifies an entry in the Repertorio delle notizie Economiche e Amministrative, the register kept by the provincial Chambers of Commerce alongside the Registro delle Imprese. The value consists of the two-letter code of the province whose Chamber of Commerce holds the entry, followed by the progressive registration number. The province code is checked against the 107 current Italian provinces and metropolitan cities, together with the codes CI, OG, OT and VS of the four Sardinian provinces abolished in 2016, because entries registered before then still carry them. The progressive number is assigned in registration order and is therefore short for early entries, so any length up to 7 digits is accepted. A space, dot or hyphen between the province code and the number is tolerated. Because the number is province-scoped it is unique only within its province, and the province code is therefore part of the identifier rather than optional context. A value consisting of digits alone cannot be validated and is reported by this rule. The REA number carries no check digit, so there is no checksum rule for this identifier, confirming that an entry actually exists requires a lookup against the Chamber of Commerce register.

For a legal entity the first three letters are derived from the legal name of the company, excluding the corporation type at the end of the name and the stop words de, del, los, las, el, la, en, y and e. If the company name has three or more words, the three letters are the first letter of each of the first three words, so El Gato Azul Restaurante, S.A. de C.V. yields GAR. If the name has two words, the three letters are the first letter of the first word and the first two letters of the second, so Gato Azul, S.A. de C.V. yields GAZ. If the name has one word, the three letters are the first three letters of that word, so Gato, S.A. de C.V. yields GAT. The next six digits are the incorporation date of the company in the order year, month and day, and the last three characters are a check value assigned by the Tax Administration Service. For an individual the first four letters are derived from the legal name: the first letter and the first internal vowel of the paternal surname, whereby the second letter of the paternal surname is used if it has no internal vowel and the first two letters of the paternal surname are used if the person has no second surname, then the first letter of the maternal surname, or the first letter of the given name if the person has no second surname, and then the first letter of the given name, or its second letter if the person has no second surname.

Identifier format invalid (Tax Identification Number (Indonesia)) REPRESENTATIONAL_CONSISTENCY	ID (Indonesia)	The tax identification number of Indonesia is known as the Nomor Pokok Wajib Pajak (NPWP). It is a set of numbers given to a taxpayer, whether an individual or an entity, for personal identification in exercising taxation rights and obligations such as income tax and VAT. It is issued by the tax office responsible for the place of residence, dwelling or activity of the taxpayer, or by the tax office appointed in a decree of the Director General of Taxes. Neither individuals nor entities are generally assigned an NPWP automatically, they are obliged to register themselves as taxpayers with the relevant tax office once they meet the subjective and objective requirements. Since July 2022 the format consists of sixteen numeric digits. The old format consisted of fifteen digits. The first two digits denoted the type of entity: the first was any number from 0 to 9 and the second was the taxpayer type code, with 0 for a government treasury, 1 to 3 for a company or organisation, 4 and 6 for an individual entrepreneur, 5 for civil servants and 7 to 9 for an individual employee. The following six digits were the serial code of the taxpayer, distributed in blocks by the central tax office to the local tax offices throughout the country for allocation to taxpayers. Then came a check digit, apparently using the Luhn, that is modulus 10, algorithm over the first nine digits of the NPWP. The next three digits were the code of the tax office where the taxpayer first registered, and the last three digits the code for central or branch status, where 000 means that the taxpayer is the sole branch, or for individuals the head of the family, while 001, 002 and so on denote each branch.

The second character indicates the year of issue, for example 1 for 2011 and 2 for 2012. Characters three and four indicate the converted month of the year of issue, which depends on the district in which the business was first established, so that January in Tirana is 13 and February in Tirana is 14, while January in another district is 25 and February in that district is 26. Characters five and six indicate the day of the month of issue, for example 01, 02 or 03.

Identifier format invalid (Taxpayer identification number (Philippines)) REPRESENTATIONAL_CONSISTENCY	PH (Philippines)	The Philippine taxpayer identification number is a numeric code of nine to twelve digits, which unlike the alphanumeric TAN makes it easier to encode.

This rule checks that structure and the format described below, disregarding any whitespaces, hyphens or dots in the value. An alternative description of the format is as follows. All Filipino and foreign citizens who are required by law to pay taxes in the Philippines must first register with the BIR to secure a taxpayer identification number, and before applying they have to know the correct type of taxpayer to register for. The number consists of nine to twelve digits, of which the first nine are the actual identification number and the last three the branch code for corporate entities, which is 000 for a single citizen.

Identifier format invalid (VAT number (Italy)) REPRESENTATIONAL_CONSISTENCY	IT (Italy)	This rule reports values held as VAT number (Italy) whose format is not the national Partita IVA of 11 digits. Spaces, dots and hyphens between the digits are tolerated. The 11 digits are made up of a 7-digit serial number for the taxpayer, a 3-digit code identifying the provincial office of the Agenzia delle Entrate that issued the number, and a final check digit. The office code is not checked against a list of provincial codes: real numbers also carry 888 for registrations under the franchise regime and 999 for non-resident direct registrations, and the provincial codes themselves change over time, so any three digits are accepted in that position. Group VAT numbers (Gruppo IVA) have the same format as the number of a single taxpayer. Values carrying the IT prefix belong to the European value added tax identifier (Italy) and are reported by this rule. The 16-character Codice Fiscale is a different identifier and is validated by the rules on Fiscal code (Italy). Note that the 11-digit form of the Codice Fiscale issued to legal entities has this same format, so a value alone does not distinguish the two identifiers. Only the format is examined here, the check digit is verified by Identifier checkdigit invalid (VAT number (Italy)).	ERROR	HYPERCARE
Identifier format invalid (VAT number (Japan)) REPRESENTATIONAL_CONSISTENCY	JP (Japan)	Japan has no separate Japanese Consumption Tax number and no distinct format dedicated to consumption tax. The consumption tax is generally associated with the business registration number or tax identification number, called the company registration number or business registration number, 登記番号 (Tōki-bangō), in Japan. This number, also known as the Tokibango or Houjin-bango, is assigned to businesses on registration with the local government and serves as the unique identification number for administrative and tax purposes, including the reporting and payment of consumption tax. The format of the company registration number is the letter T followed by thirteen numeric digits, both for sole proprietorships (個人事業主, kojin jigyoushu) and for corporations (株式会社, kabushiki kaisha). For the most accurate and up-to-date requirements it is advisable to consult the local tax authorities or a tax professional in Japan.	INFO	RELEASED

Identifier format invalid (VAT registration number (South Korea)) REPRESENTATIONAL_CONSISTENCY	KR (South Korea)	The South Korean business registration number, which also serves as the VAT registration number, is used by businesses and corporations for tax purposes. It consists of ten digits written in the form 999-99-99999: the first three digits are the administrative district code, the next two the year of business registration and the final five a sequential registration number. The number is obtained from the district tax office and identifies businesses and corporations for tax reporting and compliance. This rule checks that exactly ten digits are present, disregarding any whitespaces, hyphens or dots in the value. A value with fewer or more digits, or with unexpected non-digit characters, violates the rule.	ERROR	RELEASED
Identifier format invalid (VAT registration number (Switzerland)) REPRESENTATIONAL_CONSISTENCY	CH (Switzerland)	The Swiss VAT number is based on the Swiss UID. It starts with CHE, followed by nine digits of which the last is a MOD11 checksum, and ends with MWST, TVA or IVA depending on the part of Switzerland in which the business is registered: MWST, short for Mehrwertsteuer, in the German-speaking part, TVA, short for taxe sur la valeur ajoutée, in the French-speaking part and IVA, short for Imposta sul valore aggiunto, in the Italian-speaking part. A Swiss VAT number therefore looks like CHE-123.456.789 MWST. Combinations with the suffixes HR and RC, which indicate that the very same number is also a company identification number registered in the UID register, are permitted in any combination, for example MWST/HR or TVA/RC.

Social Security Number identified as Employer Identification Number REPRESENTATIONAL_CONSISTENCY	US (United States of America)	The United States Employer Identification Number consists of exactly nine digits, and so does the social security number. Because both are usually maintained in the same SAP field, they are easily mixed up. This rule identifies an Employer Identification Number whose format is wrong and then checks, purely on the basis of the format of the given value, whether the number could in fact be a social security number.
