If you have already received a notification from the CNMC to authorize the registration of your alias, you must complete the process for it to be properly validated.
Here are the steps to follow:
Access the notification received
Go to your email from the CNMC and open the notification to review the details.
Access the CNMC's electronic office
Go to the following link and log in with your digital certificate:
https://sede.cnmc.gob.es/tramites/telecomunicaciones/gestion-del-registro-de-alias
Select the type of request.
Within the procedure, choose the option: “Alias Authorization”.
Authorize pending aliases.
Review the aliases that appear in the request, authorize them, and complete the information linking them to your company. In “Legitimate link,” you must indicate the link between the alias and your brand, from the drop-down options. In the "Specify which one it is" section, you can write a brief explanation.
Confirm by clicking "Review and submit."
Once these steps are completed, your aliases will be properly authorized and you can continue using them normally.
