Drivers with a parking ticket can pay their fine through the GoTucson Parking app.
If you already have the app on your smartphone, make sure it's the latest version, or download for free from ParkTucson if you don't have it. The payment option can be accessed from the left-side drop-down menu. Click on "Citation Payment," enter the 7-digit citation number and the vehicle license plate, then pay by credit card. There is a 50-cent convenience fee for the service.
Please keep in mind that the app will only accept payments made within 30 calendar days of the citation. After 30 calendar days, fines must be paid to Tucson City Court.
