What is my e-TAG number?

Your e-TAG number is a 10 or 12-digit serial number printed on your e-TAG device. It uniquely identifies your particular e-TAG. 

To find a listing of all your e-TAG numbers, Log into your e-TAG account  and select eTAGs from the menu on the My Account overview page.

You need your e-TAG number to transfer (and charge) a toll notice to your e-TAG account. If you've just opened an account your e-TAG number can take up to five days to appear on your online account.
