Applies to: Spain-wide digital identity; identity-verification offices and available methods vary.
Before you start
- DNI or NIE and accepted supporting identity document.
- Email account you control and the FNMT request code.
- Compatible device with the current FNMT software.
The steps
Choose the correct certificate
Select the individual/persona física certificate. The standard in-person verification route is different from paid video-identification options.
Prepare your device
Follow FNMT’s current configuration instructions before starting. Install only software linked by FNMT and keep the request/download environment available.
Request the certificate
Enter the required identity details and your own email. Save the request code; you will need it for identity verification and download.
Prove your identity
Arrange an appointment where required. Foreign applicants should check FNMT’s accepted combinations, such as a TIE or EU registration certificate with passport, rather than taking an NIE number alone.
Download and back up
Return through FNMT’s download process, install the certificate and export a password-protected backup including the private key. Test login on the official service you intend to use.
Important details
Keep control of the key
The certificate can identify and sign for you. Do not give an agent your private-key file or password; use a proper representation mechanism.
If your details change
Use FNMT’s revocation or renewal instructions as appropriate. A stored request code is not the certificate itself.
