To ensure you’re always getting the lower TollTag rate, remember
to update your account if you get a new vehicle, license plate, or credit/debit
card information.
A TollTag customer will receive an invoice for
tolls at the higher ZipCash rate if:
(1) The customer’s TollTag account does not have updated vehicle
or credit/debit card information
(2) The customer’s TollTag account doesn’t have enough funds to
pay tolls.
If a customer does not have a TollTag account, a ZipCash invoice
is mailed to the registered vehicle owner according to the Texas Department of
Motor Vehicles records.
If the credit/debit card information for your TollTag account is
incorrect or outdated, NTTA is unable to charge the card; this can cause your
TollTag account to reach a $0 balance, and you will receive ZipCash invoices at
the higher toll rate.
You can pay these invoices and update your TollTag account
through the online Customer
Service Center or by contacting NTTA Customer Service Center at
972-818-NTTA (6882), 817—731-NTTA (6882) or by email at: CustomerService@ntta.org.
