Digital Certificates in Spain
A digital certificate (certificado digital) lets you prove your identity online and complete many official procedures in Spain without visiting an office in person.
It can be especially useful for residents, property owners and anyone who needs to manage Spanish tax, social security or local authority paperwork.
What can you use it for?
A digital certificate can help you:
Submit tax returns and access tax records.
Complete certain residency and administrative procedures.
Access Social Security services.
Check or manage local tax payments.
Submit applications and download official documents.
Sign documents electronically where accepted.
How to obtain a digital certificate
One widely used option is the FNMT digital certificate for individuals.
Apply online
Visit the official FNMT website and follow the instructions to request a certificate.
Verify your identity
Depending on the application method, you may need to verify your identity in person at an authorised office or use an available online identification service.
Download your certificate
Follow the FNMT instructions to download and install the certificate. For some application methods, you must use the same computer and browser used during the request.
Keep it secure
Your certificate can be used to access personal information and sign official documents. Protect it carefully and never share your private key or passwords.
Do you need an NIE?
Foreign nationals will generally need an NIE or other accepted identification details to apply, depending on the certificate and identification method.
Can someone help you apply?
A gestor or other professional may be able to guide you through the process. However, the certificate is linked to your identity, so you may need to complete the identity verification yourself.
