California drivers can recognize the state’s standard license-plate pattern in a heartbeat: one number, three letters, and three more numbers.
The series began with the license plate 1AAA000 in 1980, but now, 46 years later, it’s ended with the production of 9ZZZ999.
In other words, the state has exhausted every possible combination of the long-running pattern, meaning it must change the format now for the first time in almost half a century.
According to the L.A. Times, the new seven-character sequence mirrors the previous one: three numbers, three letters, and one final number, such as 123ABC4.
The change has already begun rolling out, although more than 110,000 plates with the old format remain in inventory, so some newly registered vehicles may still receive one of them.
To be clear, this is not a redesign of California’s recognizable white plate with blue lettering and red script. But eagle-eyed drivers will soon start spotting the new license plate format on the road.
Standard plates are generally issued when someone buys a new vehicle, replaces plates that are lost, stolen, damaged, or unreadable, or turns in special-interest or personalized plates for standard ones. That means the transition will happen gradually, one new registration at a time.
The hidden systems behind America’s wildly different license plates
California’s familiar 1AAA000 sequence was never the national norm. In fact, the United States does not have a standard license plate formula.
Each state develops its own system, typically combining six or seven numbers and letters in an order that can create unique combinations depending on state demand. In Delaware and New Hampshire, for example, the format uses all-numeric plates, due to their low populations.
The most common configuration is ABC-1234, with or without a space or dash. You can find it in 12 different states including New York and Texas.
When states run out of configurations, they sometimes solve the problem by adding a character, or by reversing the order of letters and numbers, like California has done.
