Frequently asked questions
Is NAF the same as NIF?
No. The NAF (Registration Number) is exclusive to Social Security and used for contributions. The NIF is the fiscal identifier (your DNI or NIE). They are different documents.
When do I need a NAF?
When starting work, if you register as self-employed, or when accessing Social Security benefits.
