The NISS is your social security number in Portugal. You need it to work legally, access public healthcare, and receive benefits.

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 whether as an employee, freelancer, or entrepreneur you need a NISS. It's also required for accessing the Portuguese public health system (SNS) and other social benefits. The application is submitted online to Segurança Social, but the forms and requirements can be confusing if you don't speak Portuguese.
