Request your NUSS (Número de la Seguridad Social) via Import@ss

Retroactive registration: 60 days. After that, contributions are not recognised.

You get your NUSS if you've never had any relationship with the Seguridad Social. It identifies you in the system (useful for kids/students). For work it doesn't matter if the employer registers you and assigns the number directly.

Guía completa

What you need to have to hand
  1. ID: DNI if you're Spanish; if you're foreign, NIE/TIE or passport if you don't have a TIE yet.
  2. Mobile for SMS (Cl@ve via SMS) and email.
  3. If it's for a minor: Libro de familia or certificado literal de nacimiento and your DNI/NIE.
  4. If you changed details (name, nationality): Registro Civil certificate/resolution proving it.
Documentation
  • DNI or NIE/TIE on both sides (clear image, no glare).
  • Passport if you only have a NIE assigned and haven't received your TIE yet.
  • For minors: Libro de familia or certificado de nacimiento, and ID of the parent/guardian.
  • If you act as a representative: simple authorisation and your ID.
Step by step
  1. Go to Import@ss: https://importass.seg-social.es/tramites/solicitar-numero-de-la-seguridad-social
  2. ID yourself with Cl@ve, certificado digital or DNIe. If you use SMS, make sure Cl@ve is activated.
  3. Fill in your personal and contact details. Tick that you never had a number if this is your first contact with SS.
  4. Attach the documents (DNI/NIE/TIE; for minors, libro de familia/certificado + parentx27;s DNI).
  5. Review and submit. If there are no issues, the NUSS is issued immediately and you can download proof.
  6. Go to Tu área personal > Datos personales and check your Número de la Seguridad Social. Download the certificate if you need it for other procedures.
Tricks that save you time
  • Before doing anything, log into Import@ss and check if you already have a number. Many people have one from internships or studies and don't realise.
  • If Safari gives you trouble with signing/attachments, use Chrome or Firefox. Fewer crashes.
  • Keep photos/PDFs under 4 MB and legible. If not, they'll return it for "calidad insuficiente".
  • If you don't have Cl@ve, register online with video or visit an office before starting. Saves pointless trips.
Common mistakes to avoid
  • Requesting a new NUSS when you already have one: you create duplicates and then it takes weeks to unify numbers.
  • Confusing NUSS with alta: the NUSS doesn't let you work; the alta must be filed by the employer.
  • Uploading blurry documents: automatic rejection and back to square one.
  • Forgetting proof of relationship when requesting for a minor: denial because representation isn't proven.
  • Data mismatches (accents/dashes different from the DNI): manual review and delays.
  1. 1.Go to Import@ss: https://importass.seg-social.es/tramites/solicitar-numero-de-la-seguridad-social
  2. 2.Identify yourself with Cl@ve, certificado digital or DNIe. If you don't have one, use Cl@ve via SMS after registering in Cl@ve.
  3. 3.Fill in your basic details (name, address, mobile, email) and confirm you were never assigned a number before.
  4. 4.Attach the documents: DNI/NIE/TIE (and, if for a minor, libro de familia/certificado and your ID).
  5. 5.Submit the application and download/save the receipt. If everything checks out, you'll see the NUSS assigned on screen.
  6. 6.Check your NUSS in Import@ss > Tu área personal > Datos personales. There you can download a certificate of the number.
  • Your DNI (if you're Spanish) or NIE/TIE (if you're foreign) scanned/photo legible on both sides
  • Passport valid if you only have a NIE assigned and not a TIE yet
  • Mobile phone with reception to receive SMS and an email address for notifications
  • If you request it for your minor child: Libro de familia or certificado literal de nacimiento
  • If you act as parent/guardian: your DNI/NIE and the document proving representation (signed authorisation)
  • If you changed name or details: proof of the change (resolution, Registro Civil certificate)

¿Qué necesito para completar Solicitud de NUSS sin que me lo rechacen?

Solicitud de NUSS es gratuito en INSS / TGSS y se puede presentar por cuenta propia. El punto que interrumpe el trámite es que hace falta Cl@ve activa, y si no está dada de alta el registro previo puede tardar días. Además, el formulario tiene 5 pasos y la sesión de la sede caduca antes de terminar si se interrumpe. GovEasy prepara el expediente completo y comprueba los datos antes de tocar la sede, y si no tienes la identificación digital lista, un gestor colegiado del marketplace lo presenta por ti.

  • Cl@ve activa (PIN o permanente)
  • GovEasy (extensión + gestor colegiado)
