Central U.S. Interoperability
TxTag now works on all toll roads in Texas, Kansas, and Oklahoma.
USInteroperabilityLocationImage

What is Central U.S. Interoperability (CUSIOP)?
CUSIOP allows drivers to use toll roads in Texas, Kansas, and Oklahoma with a single toll account. Drivers must have an active toll tag issued by the Texas Department of Transportation (TxTag), North Texas Tollway Authority (TollTag), Harris County Toll Road Authority (EZ TAG), Kansas Turnpike Authority (K-TAG), or Oklahoma Turnpike Authority (PIKEPASS) installed in their vehicle.
With interoperability, drivers can enjoy the convenience of toll roads when traveling out of state without worrying about having to buy another toll tag or getting a fine for using a toll road without paying.
Where can I use my TxTag?
TxTag can be used on all toll roads in Texas, Kansas, and Oklahoma.
Can I use a TxTag motorcycle or bumper tag in Kansas or Oklahoma?
Yes. TxTag motorcycle and bumper tags work in Kansas and Oklahoma.
Will I get my TxTag discount on Kansas and Oklahoma toll roads?
Yes. TxTag customers pay the lowest rates on toll roads in Kansas and Oklahoma, just as they do in Texas. TxTag customers are charged the same discounted toll rates as Kansas’s K-TAG and Oklahoma’s PIKEPASS customers.
Who do I contact if I have questions about my tolls in Kansas or Oklahoma?
TxTag customers should contact Harris County Toll Road Authority (HCTRA) customer service online at hctra.org or by calling 281-875-EASY (3279).
Who is going to issue my toll statements?
If you have a TxTag account, your statement will include toll charges for travel on any toll road in Texas, Kansas, and Oklahoma. You can view your toll transactions and past and current statements by logging into your account online at hctra.org.
What tags are allowed on Texas toll roads?
In addition to TxTag, drivers on Texas toll roads can pay with one of these toll tags: TollTag (Dallas-area), EZ TAG (Houston), K-TAG (Kansas), and PIKEPASS (Oklahoma).
Can I use my TxTag where an NTTA TollTag can be used for parking?
No. TxTag cannot be used for parking. The Central US program only allows TxTag customers to use their tag to pay for travel on toll roads.
If I have a TxTag and a K-TAG or PIKEPASS account, what should I do?
You should not have more than one tag on your vehicle to avoid being charged twice for your tolls. Choose which toll account you would like to keep, remove the other sticker from your windshield, and close that account.
Will the interoperability program be expanded to include more states?
Toll agencies throughout the country continue to work together in an effort for all systems to be compatible. On July 6, 2012, the federal Moving Ahead for Progress in the 21st Century Act (MAP-21) was signed into law. Under MAP-21, state tolling agencies with roadways receiving federal funds are required to make their electronic toll payment systems compatible with each other. The toll authorities within Texas have been interoperable for nearly 15 years. The expansion to include Kansas and Oklahoma is one of the first steps to accomplish the goal of national toll interoperability.
