Get in touchThe 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.
