Frequently asked questions

Is NAF the same as NIF?
No. The NAF (Social Security Number) is exclusive to Social Security and serves for contributions. The NIF is your tax 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 to access Social Security benefits.
