Frequently Asked Questions


  1. Why ZipCash?
    The introduction of ZipCash was originally implemented to provide immediate congestion relief from construction related traffic at the south end of the Tollway in early 2007. The success of ZipCash was a key consideration in the NTTA’s decision to transition to cashless tolling. ZipCash provides smoother traffic flow and streamlined billing for drivers.
  2. What is the difference between a TollTag and ZipCash?
    TollTag customers pay their tolls electronically through the use of a transponder (TollTag) mounted on their windshields. Customers maintain a prepaid account to cover the cost of tolls. Each time a vehicle with a TollTag passes through an operating toll lane, the applicable toll is deducted from the account. TollTag users save up to 50 percent in toll fees by using the automated system.

    ZipCash is the NTTA’s “drive-now, pay-by-invoice” system that allows customers without a TollTag to use NTTA tollways. Tolls are billed to the registered owner of the vehicle at a later date and at the higher rate.

  3. As a ZipCash customer, how often will I be billed?
    As a ZipCash customer, how often will I be billed? ZipCash customers receive invoices for their tolls based on their toll road usage. Invoices are mailed to the registered owner of the vehicle. ZipCash invoices can be paid online, by mail or phone or in person at the NTTA Customer Service Center or a participating ACE Cash Express location.

    ZipCash customers will be mailed an invoice for every 30 transactions. Customers with five to 29 transactions will be billed every 30 days. Customers with four or fewer transactions will be billed 30 days after they reach their fifth transaction.

    The longer a ZipCash invoice remains unpaid after the due date, the higher the related fees and fines will escalate. Customers can avoid any fees by paying their ZipCash invoices, which cover tolls only, within 30 days of receipt.
  4. What do the acronyms on my bill mean?
    DNT – The Dallas North Tollway
    PGBT – The President George Bush Turnpike
    SRT – The Sam Rayburn Tollway
    AATT – The Addison Airport Toll Tunnel
    MCLB – The Mountain Creek Lake Toll Bridge
    LLTB – Lewisville Lake Toll Bridge
    SH161 – State Highway 161
  5. How does ZipCash tolling work?
    When a motorist without a TollTag travels through designated ZipCash tolling points, a digital image of the vehicle’s license plate is captured. An invoice for the toll payment is sent to the registered owner of the vehicle.
    ZipCash is an option to pay tolls and, unlike TollTag transactions, a premium is added to each toll to cover the cost of processing. TollTag users save up to 50 percent in toll fees by using the automated system.
  6. Why does the NTTA offer the ZipCash method of toll payment?
    ZipCash is an alternative form of payment that gives motorists without TollTags the benefits of non-stop tolling. However, because of the higher cost associated with processing ZipCash transactions, ZipCash tolls cost drivers more. Non-stop tolling reduces travel time, fuel consumption and vehicle emissions. Non-stop tolling also enhances safety and decreases traffic congestion.
  7. What if I travel in a rental or loaner vehicle?
    Various rental car companies share vehicle information with the NTTA, while others offer an opt-in or opt-out choice to their customers at the time of the rental. Please ask about their individual toll policies. If a rental car company has an agreement with the NTTA, the customer may then travel on an NTTA toll road and later receive a ZipCash invoice referencing the rental car transactions. If the NTTA does not have an agreement with the rental car company and the customer chooses not to opt-in to the rental car company’s tolling plan, the customer will be subject to NTTA fees and rental agency fines.
    If you are an NTTA customer with a hard-case TollTag, you may remove your TollTag from your vehicle and place it in your rental car after you update your TollTag account online or by contacting the NTTA Customer Service Center at 972-818-NTTA (6882) with the rental vehicle’s information. If you choose this method, you must remember to update your account again with your regular vehicle information after the use of the rental vehicle ends. This option is not available to customers with sticker TollTags, because these TollTags cannot be removed. Attempting to do so will result in irreparable damage to the sticker TollTag.
  8. What if I do not pay my ZipCash invoice?
    To avoid additional fees, customers are encouraged to pay ZipCash invoices by the due date. Please see the chart for the entire ZipCash billing process:

    TollTag Basics

  9. How does the TollTag work?
    The TollTag is a small transponder that communicates electronically with a computer in the lane you are using. As you approach a tolling gantry, the TollTag will register to the appropriate account usage, which will be subtracted from your account within 24 hours.
  10. What are the benefits of having a TollTag account?
    • Save up to 50 percent compared to ZipCash customers
    • Travel any toll road in Texas with a TollTag

You may choose to receive parking receipts via e-mail through the "Preferences" page in online Account Management at

There is no cost to replace a sticker TollTag. The $25 fee for a lost or stolen hard-case TollTag pays for the loss of the transponder. The fee for a license plate TollTag is $37.50. To cancel TollTag, you must contact the Customer Service Center. All hardcase and license plate TollTags must be returned to the NTTA at the end of the user agreement.
  14. What should I do if I no longer own the vehicle
    The reason you received an invoice(s) is because the Texas Department of Transportation still shows you as the registered owner of this vehicle.
    If the vehicle was traded to a dealership, You must fax either the bill of sale or the odometer statement to 214-461-2085. If the vehicle was sold to an individual, you must file a Vehicle Transfer Notification with TXDoT. You may access the VTN information by clicking on the link below:
    Once this information has been updated with TXDoT, the NTTA will be able to close the invoice(s).
  15. What about vehicles with out-of-state license plates?

    TollTag accounts may be maintained and replenished by credit or debit card. Cash users are required to pay an additional deposit of $25 for each set of three tags. This deposit will be refunded without interest if all TollTags are returned in good condition upon closing of the account, once a cash account is converted to a credit card account.
    If your account falls to $10 or less, it may be replenished either by paying with additional cash, or, for credit or debit card users, the NTTA automatically charges an additional $40 to your credit card to increase the amount. If you accrue tolls without a positive TollTag account balance, you will receive a ZipCash invoice for those tolls at the higher ZipCash rate.

Future NTTA projects will also accommodate the use of TollTags.
  26. Why does the TollTag have to be mounted on the windshield?
    The TollTag operates on a radio frequency, and the windshield is typically the best place to ensure that the tag can be read. Some vehicles have metallic windshields which interfere with the electronic signal. In those cases, mount the tag on your license plate. Holding the tag with your hand or leaving it on the dashboard may also prevent the TollTag from being read accurately.

    Yes. If you mount a TollTag on a motorcycle, be aware that any metal located within 1 inch of the tag could cause problems, resulting in improper TollTag readings.
  28. Can I maintain my TollTag account with my credit or debit card?
    Yes, paying by credit or debit card is actually the most convenient way to maintain your account. Credit and debit cards always expire at some point, and you will need to keep your information up to date either via online account access or by contacting the Customer Service Center.
  29. What is the speed limit on the Tollway?
    Speed limits vary and are posted on the various roadways and approaches to exit and entrance ramps. Please drive carefully and remember that adverse weather conditions or other factors may make it unsafe to drive at the posted speed limit.
  30. Doesn't the TollTag keep track of my usage once my balance falls below zero?
    The TollTag account does not keep track of usage after an account reaches $0. If an account falls below $0, drivers are subject to our ZipCash invoicing rules. Notices of Non-Payment result in a additional administrative fees and may result in a citation being issued by the Texas Department of Public Safety. See question # 8 under ZipCash
