What is NISS?
“The Social Security Identification Number (NISS) is the number that allows you to access rights and fulfill duties in Social Security.
The NISS is mandatory and applicable to all national or foreign citizens wishing to work in Portugal.
Only the person who already has the NIF is eligible to apply for the NISS.
For companies, the NISS is assigned at the time of requesting the corporate NIF with the tax authority.”
Documents required to apply for the NISS:
- Photo of passport or identification document
All information contained on the identification page with 3×4 photo and the previous page must be in 1 single file, 100% legible, without fingers or shadows that hinder the reading of the information.
For European citizens, in place of the passport, the front and back identification document in 1 single file can be sent.
For German citizens, the passport must have been issued after 2017.
For children, the document to be sent must be proof of birth. At least one of the parents must have the NIF and NISS. Extra documentation may be required, to be requested by us via email after purchasing the service.
