idCAT Mobile

An ID service provided by the Open Administration Consortium of Catalonia, based on giving a single-use password to a mobile telephone, which has previously been registered with the Electronic Office of the Government of Catalonia.

What is it?

idCAT Mobile is an identification and electronic signature system intended for citizens based on sending single-use passwords to mobile devices. Citizens must register their mobile phone number with the Electronic Office database before they can use this system.

To register, you must meet the following requirements:

  • Be older than 16
  • Give evidence of identity using one of the following recognised documents: DNI, NIE reported on your residence permit, passport, identity document of a European Union country, or EU residence card or by providing information known to both parties (applicant and Administration) in the event of online electronic registration.
  • Give the required information of an email address and a mobile phone for the purpose of identification and contact.

How do I register on the internet?

The online electronic registration form offers citizens the possibility of registering their contact details with the Electronic Office without having to travel to an office in person.

The online registration process is accessible at the following address: https://idcatmobil.seu.cat.

It can also be accessed from the space My folder using the Login with ID button as shown below:

The link leads to the CAOC ID screen where the citizen can register for the idCAT SMS service:

Online registration in the idCAT SMS service can be done with a digital certificate if the following requirements are met:

  • Have a certificate of being a legal or corporate person or representative of a legal person.
  • The certificate must be valid.
  • It must be issued by an entity classified by the CAOC

People who have Spanish nationality can also choose not to use a certificate. In this case, you must prove your identity by providing the expiry date of your National Identity Card (DNI) and the barcode of your Individual Health Card (TSI) provided by CATSALUT.

You will also be asked for your mobile phone number for the purpose of identification and management of alerts and email. A single-use password will then be sent to your mobile telephone informing you that it must be entered to complete the registration process.

People who register online without using a certificate will receive, at the home address they have registered in their town council, a letter informing them of their registration with the Electronic Office. This is an additional measure to guard against impersonation.

You must fill in, sign and submit the relevant form. You must prove your identity with an ID, for example, your national identity card. All documents provided by the applicant must be valid at the time of registration. If the document provided has expired, you need to provide proof of renewal.
Registration in person at these offices is mandatory for people who are not Spanish nationals.
The number of places where you can register will soon be increased to provide better coverage across the country. 

How do you use it?

If you wish to identify yourself using idCAT Mobile, you will need to enter your national identity card number (DNI, in the case of a Spanish citizen) and the mobile phone number you have registered in the database.

If the database does not find the identity document, or mobile phone number provided is not what has been registered in relation to the identity document, you will see an error message. In this case, you must modify the registry if it is wrong or register it if you have not previously done so.

If the data provided correspond to those registered, a password will then be sent to your mobile phone to enter into the field of text shown on the screen. From that time onwards, you can carry out any procedure or relevant paperwork.

Modification and cancellation of data and temporary suspension

The system provides for changes being made to the contact details at the offices where registration is done in person and, in the near future, at the Electronic Office self-service. You can add or modify your postal address, email and phone number.

Requests for voluntary cancellation of the data must always be done in person at a Citizen Attention Office.

If an individual notices improper use of the service, they may request the temporary suspension of access to data and the opening of a verification process. The request for temporary suspension of access must be managed in person at an office enabled to do so. In the future, the request may be made by internet, although the application must be completed in person at a Citizen Attention Office.

What is the Electronic Office database?

The system holds data that facilitate the electronic identification of people who want to communicate with the Government of Catalonia. The data are provided by the person concerned or the bodies of the Government of Catalonia, with which they have dealt, in accordance with legal regulations on protection of personal data and always with the consent of the person concerned.

These data may be transferred to the Catalan public administrations and its associated bodies for identification and communication with interested persons.

The body responsible for the files in this database is the Directorate General of Citizen Services.

Uses of the file:

  • Gather the identification data required for the processing and communication of services of the Electronic Office of the Government of Catalonia.
  • Communicate electronically requests and resolutions of the services under the jurisdiction of the Government.
  • Manage the publication of notices of administrative acts and other communications of the Administration of the Government of Catalonia and other information of general interest from this administration.
  • Collect contact information necessary for the management of the response to various queries, complaints, suggestions or opinions presented through the Contact mailbox of the Government.
  • Publish on the electronic bulletin board any information of general interest, communications and actions taken by the Government of Catalonia and the other entities included in the regulations.
  • Gathering statistics.
