Frequently asked questions
NIF (Número de Identificación Fiscal) is the tax ID for Spanish citizens, it matches the DNI number plus a check letter. CIF (Código de Identificación Fiscal) is for companies and legal entities. NIE (Número de Identidad de Extranjero) is for foreign residents in Spain.
The NIF letter is determined by dividing the 8-digit number by 23 and mapping the remainder to the sequence TRWAGMYFPDXBNJZSQVHLCKE. For example, remainder 0 = T, remainder 1 = R, etc.
This validator checks the mathematical correctness of the ID format and control character. It confirms whether the number follows the official algorithm, but it does not verify whether the ID has actually been issued by the authorities.
