What you can do by phone with HCTRA
When you call 713-224-8653, you can report a lost or damaged transponder, dispute a toll charge or violation notice, set up or change your payment method, and ask about account balances. Customer service representatives can also explain toll rates for specific roads and answer questions about how tolls are calculated.
If you are calling about a violation notice, have the notice number ready. HCTRA will ask for your license plate number or transponder ID to pull up your account. If you believe the charge is wrong—for example, if you paid cash or used a valid transponder—the representative can investigate and may issue a credit or dismiss the charge.
Online account management through HCTRA's website
The HCTRA website at hctra.org lets you create an account and manage tolls without calling. You can view your account balance, set up automatic payments, add funds to a prepaid account, and read statements. The site also has a transponder registration tool where you can link your vehicle to your account so tolls are charged to you instead of generating a license plate invoice.
If you prefer not to use a transponder, you will receive a monthly invoice by mail. Paying online through your account or by phone is usually faster than waiting for a paper bill and mailing a check.
Transponder registration and replacement
HCTRA transponders are small devices you mount on your windshield that automatically deduct tolls from your account as you pass through toll plazas. If you lose your transponder or it stops working, you can order a replacement by calling 713-224-8653 or through the website. Replacement transponders typically cost around $25 to $35, depending on the type.
If you have a transponder but have not registered it with an account, you can do that online or by phone. Registration links your vehicle to your transponder so tolls are charged to your account instead of generating a separate invoice based on your license plate.
Toll violation notices and how to respond
A toll violation notice is issued when HCTRA cannot read your transponder or collect a toll through your registered account. This can happen if your transponder is not mounted correctly, your account has insufficient funds, or your vehicle was not registered to your account. The notice will include the toll amount, a late fee, and a important date to pay or contest the charge.
You have 30 days from the notice date to respond. You can pay the toll and fee by phone, online, or by mail. If you believe the charge is wrong, call 713-224-8653 with your notice number and explain the issue. For example, if you used a valid transponder, the representative may be able to see that in their system and remove the charge.
Payment methods and account funding
HCTRA accepts credit cards, debit cards, and bank account transfers for payments. You can set up automatic payments so your account is funded each month, which prevents violation notices from unpaid tolls. Prepaid accounts typically require a minimum balance, which varies but is often $25 to $50.
If you pay by mail, send your payment to the address listed on your invoice. Payments by mail take longer to process, so if you have a important date, pay online or by phone instead.
Frequently Asked Questions
What if I do not have a transponder?
You can still use HCTRA toll roads. Your vehicle will be photographed at the toll plaza, and HCTRA will send you an invoice by mail based on your license plate. You can pay the invoice online, by phone, or by mail. Registering a transponder is optional but faster and avoids the risk of violation notices if payment is delayed.
Can I dispute a toll charge if I think I was charged twice?
Yes. Call 713-224-8653 with the date and time you used the toll road. Customer service can look up your account and see if a duplicate charge was made. If so, they can issue a credit. Keep your receipt if you paid cash, as it may help prove your case.
How long does it take to register a transponder?
Online registration is when ready. If you order a replacement transponder by phone or mail, it typically arrives within 5 to 10 business days. You can use the toll roads without a transponder in the meantime; you will just receive an invoice by mail.
What if the customer service line is busy?
Try calling during off-peak hours, such as early morning or late afternoon. You can also submit a contact form on hctra.org or manage your account online if your issue does not require a phone conversation.
Do I need to call if I just want to pay a toll invoice?
No. You can pay online at hctra.org, by phone using the automated system, or by mail. Online payment is the fastest option and usually processes within one business day.
