Certificado Digital - digital signature for access to all public services in Spain

Certificado Digital is a technically and legally complex procedure. An error at any stage leads to rejection, blocking of the certificate or the need to start all over again. We take full control of the process: from the first application to the successful use of the signature on all government portals.

1. Registering a request for Certificado Digital and verifying the correctness of the data

We start with the correct application form on the FNMT website. We check:

• NIE/NIF correctness;

• matching of data from the passport and the FNMT system;

• the status of your document with the Ministry of Internal Affairs and the IRS;

• name format and alphabetic characters;

• technical parameters of the device from which the request is made.

Incorrect data will automatically block the application. We exclude this at the start.

2. Choosing the right type of certificate and preparing to obtain it

There are different types of signatures:

• Para Personas Físicas – for individuals;

• Representante – for representatives of companies;

• Autónomos is for the self-employed;

• Certificados de Administración – for administrators of legal entities.

We analyze your situation and issue a certificate of strictly appropriate type so that you can use it on all the required portals.

3. organizing identification (Registro Presencial) and accompaniment at filing

The FNMT requires face-to-face proof of identity at one of the approved registration points (Agencia Tributaria, Seguridad Social, Ayuntamiento).

We are:

• get you into the right office;

• prepare the documents and explain the procedure;

• accompany you personally;

• make sure that the data is entered by the employee without errors;

• confirm identification in the FNMT system.

Certificado Digital will not be issued without correct identification.

4. Obtaining a certificate, saving keys and technical installation on devices

After confirmation, FNMT provides a link to download the certificate. This is the step where errors most often occur:

• browser incompatibility;

• unsaved request code;

• .pfx / .cer not loading correctly;

• inability to import a certificate;

• Windows/Mac installation conflict.

We take care of the technical part:

• download the certificate correctly;

• save the key files;

• import it into the system;

• install in KeyChain (Mac) or Cert Manager (Windows);

• customize Chrome, Firefox, Safari to work with FNMT.

After that the certificate starts working stably.

5. Activation of Certificado Digital on public service portals and testing of operability

We fully test the certificate’s performance on key government sites:

• AEAT (tax office) – entry, filing of returns;

• Seguridad Social – vida laboral, registration, social services;

• SEPE – Benefits and Inquiries;

• DGT – Driver’s Data;

• CatSalut / Salud – Medical Services;

• Extranjería – applying for a residence permit and extensions;

• Ayuntamiento – trámites municipales.

We make sure the signature works correctly on all platforms.

6. Installing the certificate on the phone (Android / iPhone) and learning how to use it

So that you can use the signature at any time, we:

• transferring the certificate to the phone;

• install it on the system;

• connect to mobile browsers and apps;

• We teach how to sign documents, send requests and upload files to government agencies.

Now all state services are available in one click.

7. Support and solution of technical problems even after installation

We provide assistance if:

• certificate stopped opening after the system upgrade;

• the password’s gone;

• FNMT requires re-identification;

• signature doesn’t work in a particular portal;

You can always ask for support without having to go through the process all over again.
