Welcome to CUSIOP

Central United States Interoperability Partners

The Central United States Interoperability Partners (CUSIOP) is a collaborative group of toll operators whose collective mission is to facilitate the ease of travel and provide flexibility to the member agencies. This partnership extended to some parts of Florida in 2023 and Colorado in 2024 – Kansas, Oklahoma and Texas TollTags (transponders issued by the North Texas Tollway Authority) are compatible.

Founded in 2017, the CUSIOP group strives to be the model for synergy in achieving and sustaining regional interoperability within the tolling industry while focusing on:

  • Providing world-class customer service.

  • Being respectful to all members of the tolling community – from owners to drivers.

  • Holding ourselves accountable to each other and the mutual customers.

  • Raising efficiency standards and practices.

  • Fostering innovation in tolling and payment technologies.

  • Collaborating with other toll operators, equipment manufacturers, and technology providers.
