EZ TAG is a free Android app developed by Harris County Toll Road Authority, designed to assist motorists using toll roads in Texas, Oklahoma, and Kansas. With EZ TAG, account holders can log into their account using their HCTRA.org login credentials, while non-account holders can open an account using their credit card or bank account and order a toll tag to place on their windshield.

The app offers a range of features that enable users to manage all aspects of their EZ TAG account, including viewing their balance, adding funds to their account, managing payment methods, and viewing transactions. The app also allows users to manage their EZ TAGs and vehicles, receive push notifications and alerts, and view news and closures. In case of any roadside assistance, users can call HCTRA’s roadside assistance service directly from the app.
