A tariff code or zone number is an indication for choosing the right price for parking in the area where your car is parked.
These codes are to be found in the APP (indicative) and are shown based on the GPS location. They are also shown on the signs at the parking meter. Always be aware that you are using the correct code, especially at the border of two zone areas. Always check the number in the app with the nearest parking meter.
If you have an exemption (business, resident, doctor, etc.) then a different rate applies.
Please note: certain exemptions require written proof of the validity of the other rate.
