Identifier existence

Property	Value
A technical identifier, unique in a certain context. Technical key	IDENTIFIER_EXISTENCE
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 existence
Informal and comprehensive human-readable definition of a concept. Description	This category includes data quality rules that verify whether an identifier value is registered and exists in external authoritative sources. For example, checking whether a VAT number exists in the VIES database, an Australian Business Number in the ABN register, or a DUNS number in the Dun & Bradstreet database. The validation confirms that the identifier is not only syntactically correct but also officially registered and recognized. Non-existent identifiers might indicate typos, outdated data, fraudulent information, or records that were never properly registered. This check is critical for preventing fraud, ensuring regulatory compliance, and maintaining high-quality business partner data. The validation supports the Accuracy dimension by confirming identifiers are real, active, and verifiable against official sources.
