Frequently asked questions
Is the NAF the same as the NIF?
No. The NAF (Affiliation Number) is exclusive to Social Security and serves for contributions. The NIF is the fiscal identifier (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 access to Social Security benefits.
