Certificate revoked

To check whether the certificate is valid and has not been revoked, visit the website of the issuing entity or contact them for more information.

On the FNMT website, the "Check status" option is available in the left side menu, "Certificates" section, for both natural persons and legal entities. Click on "Request verification". 

Check certificate status in FNMT

The browser will ask you for the certificate and a response page will appear with the information. If the certificate is correct the message will be "Your certificate has just been verified. You have a VALID AND UNREVOKED Digital Certificate."

If you are unable to access the response page ("The page cannot be displayed") or the message indicates that the certificate is expired or revoked (voided), it means that the electronic certificate is damaged or no longer valid.

If the certificate is valid but has become corrupted and the status check is not accessible, you can try importing a backup copy of the certificate. If you do not have a valid copy or if the certificate has expired or been revoked, you must request a new electronic certificate.
