The Philadelphia Parking Authority has partnered with Parkmobile to provide a convenient way to pay for parking using your mobile phone. Registering is free and takes less than two minutes to join. The meterUP App takes the stress out of parking. No more searching for coins. No worries about an out-of-service parking meter. With meterUP, starting your parking session takes just a few seconds. You can extend your session on-the-go (where permitted), stop your session early, as well as save “Favorite” and recently used zones. Customers may register up to 5 vehicles to one phone number, and if youre driving a different car, you can quickly change the license plate number within the app. Users can also opt-in to receive notifications prior to their parking session expiring.
