Before you call: have this ready
- Your NISS (social security number) — the first thing they ask
- Your NIF and full name as registered
- For contribution questions: your activity start date and the months in question
- For benefits: the reference number of your application if you have one
What to expect on the call
- Menus and announcements in Portuguese; hold times spike at the start of the month and around filing deadlines.
- Agents can explain your situation and what to file, but most actual filings happen online in Segurança Social Direta — ask exactly which form or menu path you need.
- English is not guaranteed; short, concrete questions have the best success rate.
Frequently asked questions
Does Segurança Social have English-speaking support?
Not officially — English depends on which agent you get. Write down your NISS, NIF and one concrete question before calling. If the language barrier blocks you, a service like CallBehalf can make the call in Portuguese.
What number do I call for Segurança Social?
The general line is 300 502 502, weekdays during business hours. Many requests can also be submitted online via Segurança Social Direta on seg-social.pt.
What is a NISS and why do they ask for it?
The NISS is your Portuguese social security identification number. Every call, payment and benefit is keyed to it, so the agent asks for it before anything else. If you do not have one yet, the line (or your employer) can explain how to request it.
