How to find your tag number
Your tag number is the unique 10 to 12-digit serial number printed on the top or bottom of your tag device. If you want to transfer a toll invoice or notice to your account, you'll need your tag number.
To find a list of all your tag numbers, log in to your account and select 'Tags and holders' from the menu.
Or, open the Linkt app, select 'Account' from the menu and then then select 'Tags'.
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.
