What is my tag number?
Your tag number is the unique 10 to 12-digit serial number printed on your tag device.
To find a list of all your tag numbers, log in to your account and select Tags from the menu.
If you want to transfer a toll invoice or notice to your account, you'll need your tag number. If you've just opened an account, your tag number can take up to 5 days to appear online.
When you make trips using your tag, the last known plate of the vehicle that it was recorded in is shown on your Tags and holders screen in your account.
