Every Area C ticket must be activated, that is, linked to your vehicle's number plate. If you paid for your Area C ticket at an Intesa Sanpaolo bank cash machine, a parking meter, the call center, a Lottomatica or SISAL outlet (Italian lottery and bill-payment counters), or on MyAreaC (the official Area C site) while logged in to your profile, it is already active and you don't need to do anything else. With Telepass or Unipol, the ticket is activated automatically if you have enabled the service and registered your vehicle. You must activate it yourself if you bought it at an affiliated garage or online without logging in to MyAreaC.
Keep in mind that you must activate your ticket on the day you enter Area C, or by midnight of the next day at the latest. Tickets from affiliated garages and NCC school-trip tickets are the exception: activate them by midnight of the day you enter. A ticket activated on a day before you enter does not count, unless it is credit added to a plate already linked to a MyAreaC profile.
The €22.50 late ticket (“ticket differito”), for entries not paid by midnight of the day after, can only be activated from your personal MyAreaC page, under “Entro 7 giorni” (“within 7 days”), after you register your number plate.
To activate your ticket for Area C you must associate its pin number with your car's license plate.
There are several methods to activate the ticket:
