Tax Identification Number (ES-NIF)


The Tax Identification Number, Número de Identificación Fiscal (NIF), is a unique number given to every legal person and organisation (companies, associations, civil societies, public institutions etc.) required to pay taxes. The NIF is allocated by the Tax Agency [1]. There is no publicly available site to verify the ownership and validity of the number. Prior to 2008 the NIF number was called CIF. These two numbers are now merged; however, some still refer to the number as CIF.
