TGSS (Tesoreria General de la Seguridad Social): Frequently Asked Questions
How do I get a NUSS from the TGSS?
An employer normally affiliates the worker with the TGSS. If you request the NUSS yourself, the TGSS asks for ID or NIE and form TA.2/S, through Import@ss with a digital ID or at a TGSS office. As of October 2026 the TGSS charges nothing for it.
What is the difference between the TGSS and the INSS?
The TGSS assigns the NUSS, records registrations (alta) and issues the vida laboral. The INSS is the separate institute that handles healthcare entitlement and pensions.
Does a NUSS from the TGSS let me work in Spain?
No. A NUSS assigned by the TGSS is not a work permit. Your right to work depends on your nationality and immigration status, not on the TGSS number.
