The EZ TAG app offers convenience and ease for account holders, allowing them to manage various aspects of their EZ TAG account directly from their mobile devices. By downloading the app and logging in with their existing credentials, users can view their balance, add funds, manage payment methods, review transactions, and oversee their EZ TAGs and vehicles. Additionally, the app provides features such as receiving push notifications, accessing news and closures, and contacting HCTRA's roadside assistance service if needed. This streamlined approach enhances the overall user experience and ensures efficient account management on the go.

For individuals who do not yet have an EZ TAG, the app offers a simple solution to open an account using a credit card or bank account. Users can easily order a toll tag through the app to affix to their windshield, enabling them to access all toll roads across Texas, Oklahoma, and Kansas seamlessly. This accessibility and flexibility cater to both existing EZ TAG holders and new users, promoting a user-friendly interface for account creation and management. With the ability to handle transactions, account profiles, and notifications within the app, users can stay informed and in control of their EZ TAG experience.

In addition to the app functionalities, account holders can also utilize the HCTRA.org platform for specific account management tasks. This includes viewing monthly and yearly statements, addressing missed tolls or violation invoices, and accessing essential information such as FAQs and rate charts. Furthermore, the platform emphasizes safety and assistance for motorists using Harris County-operated toll roads, with the Incident Management Division dedicated to responding to incidents and aiding stranded drivers. By offering a comprehensive range of services and support options, both through the app and website, EZ TAG users can navigate their toll road experiences efficiently and securely.
