The main number for Harris County Toll Road Authority is 281-875-3279
Harris County Toll Road Authority (HCTRA) operates the toll roads in the Houston area, including the Sam Houston Tollway, Hardy Toll Road, and Westpark Tollway.

What HCTRA handles over the phone
When you call 281-875-3279, you can ask about account balances, make payments, dispute a charge, set up a payment plan for unpaid tolls, or ask about a toll notice you received. Representatives can also explain how tolls are calculated on specific routes and answer questions about transponder use or tag replacement.
If you are calling about a toll citation or notice of violation, have the notice number in front of you. The representative will need it to pull up your account and explain what happened. If you believe a charge is wrong, the phone line is where you can start a dispute, though you may be asked to submit documentation online afterward.
When to call versus using the online portal
The HCTRA website at hctra.org lets you check your balance, add funds to your account, view your transaction history, and update your payment method without waiting on hold. If your issue is straightforward—you need to know your balance or make a one-time payment—the website is faster.
Call 281-875-3279 if you need to discuss a disputed charge, negotiate a payment plan for a large balance, or if you have received a toll citation and want to understand your options. You should also call if you are having trouble accessing your online account or if your situation is complex enough that you need to speak to a person.
Toll debt and vehicle registration holds
If you have unpaid tolls, HCTRA can report the debt to the Texas Department of Motor Vehicles. Once reported, the state may place a hold on your vehicle registration renewal. When you call HCTRA, ask whether your account has been reported to the state and whether setting up a payment plan can stop or reverse a registration hold.
If a registration hold is already in place, you may need to contact both HCTRA to resolve the toll debt and the Texas DMV to clear the hold from their system. HCTRA's representative can tell you the current status and what steps come next. Paying the toll debt does not always when ready remove a registration hold—the state may need a few business days to update their records.
Hours and what to expect when you call
HCTRA's customer service line is open Monday through Friday. Call times vary by season and demand, but you should expect to wait during morning and late afternoon hours. Have your account number, license plate number, or the toll notice number ready before you call so the representative can find your information quickly.
If you cannot reach someone during business hours, use the online portal to submit a question or check your account status. HCTRA also sends email confirmations for online transactions, so you will have a record of any payments or disputes you file through the website.
Mailing address and other contact options
If you prefer to write, HCTRA's mailing address is Harris County Toll Road Authority, P.O. Box 61010, Houston, TX 77208. Mail is slower than calling or using the website, but it creates a paper record if you are disputing a charge or need documentation for your records.
For toll citations or violations, you may also receive instructions on the notice itself for how to respond or contest the charge. Follow those instructions carefully, as citations have important date for response. If you miss the important date, you may lose the right to dispute the charge.
Frequently Asked Questions
What if I call and get a busy signal or long hold time?
Try calling early in the morning or mid-afternoon on a weekday. If the line is consistently busy, use hctra.org to handle your issue online instead—most account tasks can be done without calling. You can also submit a question through the website's contact form and wait for an email response.
Do I need to have a transponder to use HCTRA toll roads?
No. You can pay tolls by transponder, by license plate (the road photographs your plate and sends you a bill), or by paying in advance online. If you use the roads without a transponder and do not pay, HCTRA will send you a toll notice. Call 281-875-3279 to discuss payment options if you receive a notice.
Can I dispute a toll charge if I think I was charged twice?
Yes. Call 281-875-3279 with your transaction details or the dates you used the road. Have your toll notice or account statement ready. The representative can review your history and start a dispute if the charge appears to be a duplicate. Disputes usually take a few weeks to resolve.
What happens if I ignore a toll notice?
HCTRA will continue to add fees and may report the debt to the state, which can result in a registration hold. Eventually, the account may be sent to a collection agency. Call 281-875-3279 as soon as you receive a notice to discuss payment or payment plan options before the debt grows.
