To change the identity document associated with your idCAT mobile (for example from NIE to DNI) you will have to go in person to request the deregistration at an ER idCAT mobile and later you can process the registration with the new document.

To modify your data, go to " Manage your idCAT Mobile " and select the option according to your case:

If you have access to the mobile number with which you registered, press the option "Modify my idCAT Mobile" and identify yourself.

Once inside you can modify the following data:

  • Mobile number
  • e-mail
