FAQ
Common questions.
What is the NISS for?
It's your Portuguese Social Security number — needed to work legally, access public services and healthcare, and it's required for routes like the D3 visa.
Do I need it for my visa?
Some routes require it (for example the D3). We tell you whether your specific visa needs a NISS and handle the registration.
Can you register it for me?
Yes. We prepare and submit the registration with Segurança Social and deliver your NISS.
Do I need a NISS if I'm self-employed?
Yes — if you work in Portugal, including as a freelancer or company owner, you'll generally need a NISS to register your activity and contributions. We handle the registration.
Is the NISS the same as the NIF?
No. The NIF is your tax number; the NISS is your Social Security number. They serve different purposes and many people need both — we can arrange each.
How long does NISS registration take?
It's usually a quick administrative step once your documents are ready. We confirm the current turnaround when we start your registration.
