How to Get Your Portuguese NISS Number (Social Security)

Who Needs a Portuguese NISS Number and When The Número de Identificação de Segurança Social (NISS) is the Portuguese Social Security Identification Number. It is essential for anyone who intends to work, live, or access social security benefits in Portugal. This includes expats and expats, digital nomads, retirees, and anyone who plans to engage in any activity that requires social security contributions or benefits. You will need a NISS before you start legally working in Portugal, as it is required for tax purposes and to access healthcare and other social services.

Obtaining a Portuguese NISS Number Online As of my knowledge cutoff in 2023, the process of obtaining a NISS number can be initiated online, but it may require in-person follow-up depending on your situation. The online service is available through the Social Security Direct (Segurança Social Direta) website. Here is a step-by-step guide to obtaining your NISS online:

Visit the Social Security Direct website at https://www.seg-social.pt/seguranca-social-direta . Register for an account if you do not already have one.

Fill out the application form with your personal details, including your NIF and residence information. Submit the form and any required documents. Typically, you will need to provide a copy of your passport, proof of address in Portugal, and your work contract if applicable. After submission, you will receive a provisional NISS number. The final NISS will be issued after your documents are reviewed and approved. The online process is generally faster and more convenient, but it may not be available for all applicants. If you encounter issues or if your situation requires a more detailed review, you may need to complete the process in person.
