Frequently asked questions
Is NAF the same as NIF?
No. The NAF (Affiliation Number) is exclusive to Social Security and serves for contributions. The NIF is the fiscal identification number (your DNI or NIE). They are different documents.
When do I need the NAF?
When you start working, if you register as self-employed, or when you need to access Social Security benefits.
