Identifier consistency

Property	Value
A technical identifier, unique in a certain context. Technical key	IDENTIFIER_CONSISTENCY
The human-friendly name shown for this concept in the user interface, used instead of the technical name to improve readability and understanding. Display name	Identifier consistency
Informal and comprehensive human-readable definition of a concept. Description	This category encompasses data quality rules that verify the consistency of identifiers that have defined relationships or dependencies. Some identifiers are constructed from or must align with other identifiers. For example, the French SIREN number is part of the French VAT number, and these must be consistent with each other. Similarly, a company's local registration number might be embedded in its tax identifier. These rules check that when multiple related identifiers exist for the same entity, they maintain their expected mathematical or structural relationships. Inconsistencies can indicate data corruption, manual entry errors, or mismatched records. This validation is essential for data integrity in the Consistency dimension, ensuring that interdependent identifiers remain aligned and coherent across business partner records.

Inconsistency between BIC FI and EU VAT ID FI (Finland) CONSISTENCY	FI (Finland)	The Finnish business identity code and the Finnish European VAT number carry the same value: the digits of the VAT number are identical to the business identity code. This rule reports an inconsistency whenever the eight digits following the FI prefix of the VAT number differ from the eight digits of the business identity code. The business identity code is usually written in the form 1234567-8, the rule ignores the dash as well as the FI prefix of the VAT number.	WARNING	RELEASED(2020-12-28)
Inconsistency between Business Number and GST number (Canada) CONSISTENCY	CA (Canada)	The Canadian business number consists of nine digits, and the Canadian GST number is built from it: nine digits that are exactly the business number, followed by the letters RT, which mark the value as a GST number, followed by a four-digit suffix such as 0001 or 0002. An entity can hold more than one GST number, for example when it runs two separate businesses, in which case the first carries the suffix 0001, the second 0002 and so on. This rule checks that both a GST number and a business number are present and that the first nine digits of the GST number are identical to the business number. If they are not, either the GST number or the business number is wrong.	ERROR	RELEASED(2020-12-28)

The Indian GST number is built around it: a state code, then exactly the ten characters of the PAN, then a digit giving the number of entities registered under the same PAN, then the letter Z by default, and finally a checksum character that can be a digit or a letter. This rule checks that both a PAN and an Indian GST number are present and that the ten characters inside the GST number are identical to the PAN.
