What is my tag number?
Your tag number is the unique 10 or 12-digit serial number printed on your tag device.
To find a list of all your tag numbers, log into your account and select eTAGs from the menu.
If you want to transfer (and charge) a toll notice to your Tag account, you'll need your tag number. If you've just opened an account your tag number can take up to five days to appear on your online account.
