To maintain the **validity of the driving license**, it is important that personal data is up to date. If there is a change in any of this data, such as the **address**, it is necessary to **inform the corresponding Traffic Headquarters**. This should be done as soon as possible, and in the case of changes in the vehicle registration certificate, it must be reported within **15 days following the change**.

It is not sufficient to wait until the next renewal of the license to update the data, as it is mandatory to keep the information updated at all times. Additionally, if the license is lost or stolen, a new one must also be requested.

Therefore, the correct action in the event of a change in the driving license data is to **inform the Traffic Headquarters** to avoid legal issues and ensure that the license remains valid.
