For how long must my residence certificate / padrón be valid?

The residence certificate issued by the Comú / Town Hall must be valid for a maximum of 3 months from its date of issue at the time of the season pass’ purchase.
In the case of Canillo residents, the certificate must also be issued within 3 months of the date of issue, and they must have been registered with the Comú for at least two years to obtain the special price.
