E‑ZPass ETC transponders do not work on all toll roads in the United States. Currently, the E-ZPass electronic toll-collection system (as well as the other ETC systems that are part of the E‑ZPass network) are not compatible with most Florida systems (including SunPass), California's FasTrak, Kansas's K‑Tag, Oklahoma's Pikepass, Texas's TxTag, Utah's Express Pass, Puerto Rico's AutoExpreso, Georgia's Peach Pass and Cruise Card, or other ETC systems outside of E‑ZPass operating regions. Under MAP-21, passed in 2012, all ETC facilities in the United States were supposed to have some form of interoperability by October 1, 2016; however, no funding was provided for this effort, nor were penalties established for failure to meet this deadline, and this has yet to be accomplished.
