California Is About To Run Out of License Plate Numbers (thedrive.com) 160

California is projected to run out of its current license plate number format by the end of 2025, prompting a transition to a new sequence that flips the current structure. The new format will consist of three numbers, three letters, and one number and will debut soon. The Drive reports: The current system for non-commercial vehicles, which consists of one number, three letters, and three numbers, was rolled out in 1980, and the DMV expects this sequence to run its course before the year is out. But, running out of license plate numbers isn't as alarming as it might sound: California officials has already announced the next sequence.

It's relatively difficult to predict precisely when California will issue its last current-style plate, but in June 2024, The Sacramento Bee wrote that the California DMV was sitting on about 18 months' worth of license plate numbers, pegging the final current-style plate for the end of the year. The system, which started with 1AAA000, will be replaced with its reverse. The new system will consist of three numbers, three letters, and one number, so the first one could be something like 000AAA1 or 001AAA1 or 100AAA1 depending on whether or how they exactly implement the existing "no leading zeroes" rule.

      I know of a legislation where an additional fee for vanity plates was considered illegal because the DMV is a governmental service, and the service fee should be the same for the same administrative act.

          It should cost extra to have the plate made, sure. But it shouldn't (as some jurisdictions I know of here in Australia do) have an additional annual fee for the personalized plate.

          • now you're getting into minutia of cost vs benefit. If it's legal to charge extra for a custom request, it's legal to charge extra regardless of how that's structured.

          • Nothing in the US Constitution prohibits states from charging for things. I think even getting a legal copy of a birth certificate costs around $35 depending on the state. Which you need to provide if want a Real ID compliant driver's license or state id. (not every American has a birth certificate for Real ID). And the next step is all states will require a Real ID for voting. Which will be fun because you pay for the ID and pay for the birth certificate and may or may not have the other paperwork you nee

      They cracked down on personalized plates about 10 years ago. I had my firearm related personalized plate revoked for no apparent reason after having it for a decade.

      Best I've heard of was another state where a mother had "PB4WEGO" on her minivan before the state revoked it.

        I hike a lot and have done about 12.75% of the Appalachian Trail. I have the trail name "Moof". I got a custom plate with my trail name on it and the state put "AT" at the end of it to indicate the money was in support of the Application Trail Conservancy. I was never quite comfortable with it saying, "M00FAT", but I don't know of any complaints about it.

    We love cars, but we're gonna be fine.

    • Only assuming the number is completely unstructured. The current and new formats each allow 10^4 * 24^3 (assuming no o or i) which is 138,240,000. California has about 1.8m new cars a year, so this new format is good for about 76 years.

        Except that the current one lasted 45 years. No leading zeroes accounts for a bit of the discrepancy, but there must be some additional factor at play.

        • Hmm, well I used the figure for car sales, but I guess commercial vehicles and motorbikes need to be added on. Then there's cars being re-registered from other states. Do cars get a new number if they're de-registered and re-registered later? And I guess some combinations are probably banned as they spell something offensive. Some numbers seem to have been skipped, and you need a bit of headroom to give you time to bring in a new system. So 45 years is about right.

        Do they not recycle numbers?

        • Do they not recycle numbers?

          That would be a good question - apparently California does not. Certainly in my state of PA, there is nothing prohibiting it.

          If I were to hazard a guess, the Cali system was designed long before it was so easy to track different license numbers, as in they were kept track of on paper.

        • Do they not recycle numbers?

          They can't. In California, if you can find a set of California plates that have been registered at some time in the past, you can bring them to the DMV and get them registered again to your car. If they recycled numbers, there could be duplicate registrations (or they would have to change the rules on re-using using old plates).

        There's only a problem because the DMV is being lazy. As of Jan 1, 2025, there were 35,983,261 cars registered in California. If the DMV wanted to use all available numbers, there would be plenty of numbers. After all, the population of California is basically flat, and generally when people get a new car, they retire the old one, so the total number of cars is basically stable.

        There's only a number shortage because the DMV is not reusing previously allocated numbers.

          I have the old California plates off my car from when I registered it in California. I could ship the car back to California and demand that my old plates be reinstated.

      What we need is base64-encoded QR codes on plates. That'd fix the problem.
      • What we need is base64-encoded QR codes on plates. That'd fix the problem.

        We should switch to 128-bit plate numbers so we'll be sure we never run out. They'll be kind of unwieldy, but that's easy to manage if we define a convention for abbreviating out long strings of zero bits. Say, if you have a chunk of zeros you can replace them with "::", or something like that. Oh, and we can also use this to assign many plate numbers to each car, so car owners can change their plates regularly without needing a new number assigned by the state. For example, we could reserve the last 48

    I would suggest adding @, $. #, %, and &. As possible numbers.

    "Numberplate Address Translation"

    Most cars rarely leave their home town. So allocate number plates to each city. Then cities issue their own internal number plates, and any cars leaving the city just borrow a city-owned plate for the trip. The city keeps a registrar of which local plate corresponds to which state plate at any given time.

    This of course is just a temporary measure, until the new national 16-letter number-plate system is launched. It will take a few years for everyone to update their forms to accommodate that.

      That is what Japan does. They have the city name on the plate, then a letter and usually a four digit number.
      • Many states in the south love to put the owner's county of residence on their plates.

        • Nebraska, right in the middle, does as well.
          Given that they number by population, IE omaha is #1, Lincoln #2, and so on. There is a touch of an issue because 63 and 64 trade places regularly.

      • Germany, too. The first 1-3 letters denote the place of registration. They can also be used to mark a special vehicle, like one used by state officials (BD). Then you get 1-2 letters and 1-4 numbers. These you can either choose yourself or get random ones.

        UK too, although it's not so obvious. Two of the letters in the block of three are a - sometimes quite cryptic - reference to the location of the original registration centre back before everything got computerised, but the regional allocations have still been retained. There was a slight change when we moved from the two previous formats to the next one, but there are lists available online if anyone is curious (or just want to know where to go to showrooms in order to get a vehicle with their initials i

Every time you see someone from Nord Hoorn (a town on the Dutch border) where the license plates start with NOH you can pick on them by calling them Nord-Oost Hollanders. They really like that and will welcome you with open arms. Trust me. Totally not with clenched fists.

        It's also done in Austria (where they put the flag of the municipality registering it as well)

    Texas is up to at least V in their current AAA-9999 series that they've been using for around 20 years. But it's no big thing. They interrupted an AA9-A999 series (if I recall correctly) before that after only a few years. Those plates had a background that went into the number area, maybe that had something to do with why they ended it, though it seems like a silly reason to suddenly start a new number series. I would not be surprised to see them resume it when the current series runs out.

    Our plates used to be 3 letters 3 numbers and a letter that told the year. Then we switched to year letter 3 numbers and 3 letters. We changed again later to 2 letters 2 numbers 3 letters. Our plates are mostly fixed for the life of the vehicle, When registered it gets a plate that stays with it unless you spend money to change it, There are rules about what is allowed.
    • Our (California's) plates also stay with the vehicle as long as the registration doesn't lapse, and sometimes then as well.

    I really don't think they will end up rolling out the new license plates (LPv6) as soon as predicted. Most of the existing license plates will just be used behind a NAT.

      Quadruple the number and call it license plAAAAtes. Then wait 20 years for everyone to upgrade to a new plate.

  • This means no more cars can be sold in California. There's no solution, we're fucked.

  • Running out of 7-digit ASCII plate numbers is a strong sign you have too many highway vehicles. Stop allowing new vehicle registrations and start playing catchup on the century long backlog of railroad and public transportation expansion.
  • Why not just have car manufacturers hard code (stamp) a number onto the back of every car? This would eliminate the need for plates all together. When you purchase the car the license number is automatically associated with the buyer. This would eliminate the hassle of visiting the DMV for plates and registration (which I loath) and also save a ton of metal resources on the plates themselves. Seems so obvious to me.

  • Maybe the problem is not having few letters on the plates, but too many cars that need plates.

    • So what you're saying is, too many people are financially able to achieve major goals, like owning a car (or 2 or 3)? No, we can't have that. Make everyone poor again, that will fix the problem.
