Q2: Why is there a need to key in a 10-digit In-Vehicle Unit (IU) number?

A3: You can update your mobile number and email address, at both MyHDB Page and Singpass.

Q4: Why do I have to top-up for a change in car park?

A4: Different car parks may charge different rates. Please refer to the table under Monthly Season Parking Charges for the relevant rates charged for different car park types.

Q5: Why is my car park not detected when I key in the postal code/ address of my car park?

A5: Please search using an HDB residential address.

Q6: Why can’t I change my In-Vehicle Unit Number when changing car park?
