Who has to have one
Anyone taking up employment, registering as self-employed, or building up public healthcare contributions in Bilbao. Employers in Bizkaia routinely ask for it before your first working day.
How we handle it
We complete the TA.1 form, arrange the appointment with the Tesorería General de la Seguridad Social, and obtain your NUSS — in most cases within a handful of days.
In Bilbao
The Bilbao office sets the pace for the social security number across the Basque Country. Our team books your appointment, checks your documentación, and walks you through the day itself.
Frequently asked questions
In practice yes — the NIE identifies you in the system. We sequence both so the social security number follows the NIE without delay.
