Electronic Signature in Spain within one day

⏰ 6 min read


In Spanish legislation, the Electronic Signature becomes an essential tool, giving documents legal validity and ensuring security and authenticity in electronic format. Similar to a handwritten signature, the digital certificate acts as an electronic document confirming the user's identity in the online space.

Addressing a high volume of requests, we've developed a process that allows obtaining an E-Signature online within one working day. In contrast, previously, this process took weeks (in line with Spanish realities). The certificate facilitates simplified communication with government agencies online, enabling the submission of requests and documents digitally. Furthermore, it identifies the signer and records the document's status when signing, making changes or additions impossible after this stage.

Why do you need an E-signature?

Today, most interactions with governmental or municipal structures can be resolved from home, promptly and without queues.

In particular, the certificate allows you to:

  • Submit tax declarations or view data from previous years, pay fines
  • Renew and extend residency
  • Obtain a report on your «vida laboral» (work history)
  • Obtain a marriage or birth certificate
  • Submit applications and documents for recognition of educational diplomas
  • Obtain a certificate of no criminal record
  • Apply for unemployment benefits, and so on

These are just a glimpse of the vast possibilities that having a digital signature opens up for you. Explore more and discover the convenience and efficiency it brings.

How long is the digital signature issued for?

In Spain, the Certificado digital can be obtained in two ways: in person through government agencies or online. When registering through government agencies, you receive a signature for two years; when obtaining the digital signature remotely, you can choose a duration from one to five years.
