NISS (Número Identificação Segurança Social)

The Social Security Number (Número Identificação Segurança Social - NISS) is obtained from the Segurança Social, a budgetary organization that provides social support and budget revenues. 

The execution period is 1 week (depending on the method of receipt).

Option 1: Labor contract.

Required documents:

- Labor contract.
- Passport, visa, residence permit - legal stay in the country.
- NIF.

Get NISS without the employment contract is impossible, and by law without the NISS labor contract will not work. Therefore, first you sign a pre-contract - Contrato de promessa, which contains information about the reserved workplace for the employee. This will allow him to get a social security number for foreigners. And then sign a valid employment contract.

Option 2: The IE.

When a sole proprietorship is registered with the Tax Office, the entrepreneur's employment commencement data is automatically transmitted to Segurança Social. A letter with a social security number will be sent to his home address (email). 

Option 3. Student Visa.

Students can obtain an NISS by providing the following documents:

- Passport, student visa, residency.
- Matrícula - confirmation of enrollment from the educational institution.


Option 4. Family Reinstatement.

A prerequisite for NISS is that at least one family member has a Segurança Social number. An employment contract is not required.
