Confirm which office covers your address or employer, and ask about video help if a visit is difficult.
Prepare form TA.1 and accepted identity evidence: DNI (Spanish national identity card), foreigner card or passport as appropriate. Check whether a number already exists before requesting another. Online and assisted channels have their own identity checks; use the instructions supplied by TGSS (Spain’s social security registration office) and do not treat an application receipt as confirmation of employment registration. The linked Importass NUSS (social security number) request asks for DNI/NIE details, your usual address, mobile and email. Without a NUSS you cannot identify by SMS. The route without Cl@ve/certificate uses identity-document photos and a selfie; do not assume that the general counter’s passport option also means an adult passport-only online application is accepted. A parent/guardian applies for a child with TA.1, identity and family/guardianship evidence; emancipated minors provide emancipation evidence. Follow the full current checklist in the application. If a number is already assigned, use Importass “Acreditación del Número de la Seguridad Social” to consult it and download proof of your existing NUSS/NAF instead of requesting another number. An existing number may come from earlier work or school insurance. This proof identifies the number; it does not certify current employment registration or entitlement to a particular benefit.
