NISS registration for expats in Portugal

The NISS is your social security number in Portugal. It becomes relevant when you start working in Portugal or need to handle social security steps tied to your move.

Even if your situation does not fit this service exactly, I can often still help

This page covers the most common case. If your situation is slightly different, involves extra paperwork, correspondence, or does not fit neatly into one service, get in touch and we can look at it together.

What is it?

The NISS (Número de Identificação de Segurança Social) is Portugal's social security number. If you plan to work in Portugal as an employee, freelancer, or entrepreneur, you will usually need a NISS. It is part of the social security system, while healthcare registration through the SNS or utente number remains a separate step. The application is submitted to Segurança Social, but the forms, documents, and route can be confusing if you do not speak Portuguese.
