California to Overhaul License Plate Sequence After 46 Years Due to Exhausted Combinations
California is changing its license plate sequence for the first time in 46 years because it has run out of available combinations.
Chicago, IL, September 12, 2026 — California is set to implement a significant change to its vehicle license plate numbering system, marking the first alteration in 46 years. The state is transitioning to a new sequence due to a depletion of available combination codes under the current format.
The decision to update the license plate sequence comes as the existing system has reached its capacity, with no further combinations available for new registrations. This situation necessitates a broader change to accommodate future vehicle needs.
The current license plate format has been in use for nearly half a century. The specifics of the new sequence format, including the exact number of characters and the order of letters and numbers, have not been publicly detailed. Information regarding the timeline for the implementation of the new plates also remains undisclosed.
As a result of running out of available combinations, California will introduce a new system to ensure continued issuance of unique license plates for vehicles registered within the state. Further details concerning the new alphanumeric structure and the rollout plan are expected to be released by the relevant authorities.
