We prepare your request and follow it up with Segurança Social, so you don't have to.

5Good to know
Why you'll need a NISS
Your employer will want it on day one, since it's how you get paid a salary. You'll also need it to register as self-employed and to use some public services.
Get these in place first
Start with your Portuguese NIF. If you're an EU citizen staying more than three months, you should also register your residence and get your CRUE certificate.
Going freelance?
Your contributions are based on the income you declare, so your annual IRS tax return matters. Keep it in order and your contributions stay accurate.
Working in Spain instead? Take a look at the Spanish social security number (NUSS).
