NISS registration for expats in Portugal

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

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.
