Why identity verification is mandatory

A digital certificate allows you to sign documents and complete official procedures with full legal validity; therefore, the issuing authority must reliably verify the applicant's identity. This verification is the only step that might require in-person attendance.

Verification methods

  • In person: at an authorized registry office (Tax Agency, Social Security, Town Halls, etc.), with prior appointment and ID document.
  • With electronic Spanish ID (DNIe): using an active DNIe and a smartcard reader, without traveling.
  • Video-identification: offered by some certifying authorities for natural persons, with specific technical and identification requirements.
  • From abroad: Spanish consular offices serve as authorized registration offices for selected certificate types.

Foreign citizens with NIE

If you hold a NIE number you can obtain a digital certificate. Required documents depend on whether you are an EU citizen or third-country national (residence card, EU registration certificate, or valid passport with the NIE certificate).
