Tax-exempt numbers are unique identifiers issued by the Agencia Estatal de Administración Tributaria (AEAT) to Spanish companies and individuals, and to foreign residents. These numbers must be included on all legal documents. To comply with validation requirements, some companies must change their tax-exempt numbers, and will post transactions using both their old and new tax-exempt numbers.
The three tax-exempt numbers are the Código de Identificación Fiscal (CIF), Número de Identificación Fiscal (NIF), and Número de Identificación de Extranjeros (NIE).
