Social Security Identification Number can now be requested online


Foreign and Portuguese people with lifetime ID card (bilhete de identidade) can now request the Social Security Identification Number (NISS) online.

The request is made by filling out a form, available on the Social Security portal, to which a scanned copy of the ID document must be attached.

If the NISS request is made by a representative person, it is necessary to attach his/her identification document as well as proof of representation.

After the request, you will receive an e-mail confirming the allocation of the NISS and instructions to collect the NISS in person at the Social Security services. The collection can only be done by the person himself, upon presentation of the ID document.

For more information about the NISS, please consult the Social Security portal and the Practical Guide.
