Social Security Identification Number (NISS)
The Social Security Identification Number (NISS) is a number assigned upon registration in the Social Security system.
It is a unique and lifelong number that allows the identification of the employer and the worker/citizen in all matters related to Social Security.
The Social Security Identification Number (NISS) of workers and citizens is assigned upon registration in the social security system as follows:
- manually - Social Security services are responsible for the registration and assignment of an NISS
- automatically - in the future, contributors will be able to access their registration and respective NISS online (Online under construction)
Currently, one week after registration, the services notify applicants of their NISS as follows:
- ENIN: by email
- Workers enrolled on the general regime on a voluntary basis: by e-mail
- Employees: the employer is notified by e-mail. Employees should then request their NISS to the employer’s human resources
- Citizens covered by the non-contributory regime: in person, at social security offices in Dili and social security offices in municipalities and RAEOA
In any case, both contributors (ENIN, employee and worker registered on the general regime on a voluntary basis) and citizens covered by the non-contributory regime can contact Social Security services directly to request their NISS.
Social Security services can be reached in person in Social Security offices in Dili, in the municipalities and RAEOA, or by email to seguranca.socialtl@gmail.com.
In the case of national citizens working abroad, after registration and assignment of the NISS, Social Security services notify the worker by e-mail.
The Social Security Portal was supported by the International Labor Organization (ILO) within the framework of the GIZ and ACTION/Portugal projects
