Parking.sg is used for coupon car parks as an alternative for paper coupons. Parking.sg does not contain any car parks that are installed with the EPS gantries, so you will not be able to trigger a parking session for a car park implemented with the EPS/Parking@HDB, unless the wrong carpark is selected. Payment for car parks implemented with the EPS will be made through the existing IU. Parking@HDB is a parking system that is currently trialed at car parks implemented with the pilot Smart Parking System. Similarly, you will not be able to trigger any parking sessions from Parking.sg when entering car parks implemented with Smart Parking. If you have accidentally paid for a wrong carpark, please contact us below.
