How AEAT compares

AEAT is NOT the same as the Policia Nacional or Spanish consulates, which issue the NIE (Numero de Identidad de Extranjero) foreigner identity number; AEAT issues and administers the NIF (Numero de Identificacion Fiscal) tax identification number, though for foreigners with a NIE, the NIE number doubles as the NIF. AEAT is also distinct from the Banco de Espana, which supervises banks rather than collecting taxes, and from the Seguridad Social, which handles social security contributions separately from AEAT's tax remit.
