A TollTag customer
will receive an invoice for tolls at the higher ZipCash rate if:
(1) The customer’s
TollTag account does not have correct vehicle, license plate or credit/debit
card information
(2) The customer’s
TollTag account doesn’t have enough funds to pay tolls
(3) The TollTag was
installed incorrectly and cannot be detected by our system. Be sure your
TollTag is placed on the inside of your vehicle’s windshield, below the
rearview mirror.
If a driver does not have
a TollTag account, a ZipCash invoice is mailed to the registered vehicle owner,
according to 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information for your TollTag account is incorrect or outdated, NTTA is unable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 tolls incurred to the card; this can cause your TollTag account to
reach a $0 balance, and you will then receive ZipCash invoices at the higher
toll rate.
You can pay these
invoices and update your TollTag account through the Online Customer Service System or by contacting the NTTA Customer Service
Center at 972-818-NTTA (6882) or 817-731-NTTA (6882).
