What California custom plates are and who orders them

California custom plates let you choose your own combination of letters and numbers instead of accepting the random sequence the DMV assigns. You can pick almost any combination you want — within limits — and the plate becomes yours as long as you renew it. Custom plates cost more than standard plates and take longer to arrive, but they stay with you even if you change vehicles, as long as you transfer them properly.

Custom plates are different from vanity plates, though Californians often use the terms interchangeably. Both let you choose your own characters. The main difference is that vanity plates have a specific theme (like environmental plates or military plates), while custom plates are purely your choice. You can order custom plates when you first register a vehicle or add them to a vehicle you already own.

You order custom plates through the California DMV, either online at dmv.ca.gov, by mail, or in person at a DMV office. The DMV checks your chosen combination against a list of reserved plates and plates already in use. If your choice is available, you can reserve it while you complete the rest of the registration or transfer process.

Key Takeaways

  • Custom plates in California cost between $50 and $100 more than standard plates, depending on the plate type you choose, and you pay this fee every time you renew.
  • You can reserve a custom plate combination online or by mail before you complete your registration, and the DMV will tell you when ready if it is already taken.
  • Custom plates take 4 to 8 weeks to arrive by mail after the DMV approves your order, so plan ahead if you need them by a specific date.
  • Certain letter and number combinations are permanently reserved by the DMV and cannot be ordered, including those that spell profanity or offensive terms.
  • Once you own a custom plate, you can transfer it to a different vehicle by submitting a transfer form, but you must keep renewing it or it returns to the available pool.

How to check if your custom plate choice is available

The fastest way to check availability is through the DMV's online custom plate search tool at dmv.ca.gov. You enter your desired combination of up to seven characters (letters, numbers, or a mix), and the system tells you within seconds whether it is available, reserved, or already assigned to another vehicle. This search is free and does not reserve the plate.

If you want to reserve the plate while you are checking, you can do so online during the same session. The DMV will hold your reservation for 30 days while you gather documents and complete your registration. If you do not finish your registration within 30 days, the reservation expires and the plate returns to the available pool.

You can also check availability by phone at 1-800-777-0133, though this takes longer than the online tool. If you prefer to work in person, any DMV office can check availability and help you reserve a plate, though you may wait in line.

The cost and timing of custom plates

Custom plates cost more than standard California plates. The exact amount depends on which type of plate you choose. A standard custom plate typically costs $50 to $100 more than a regular plate at the time of registration. This fee is in addition to your regular registration fees. When you renew your registration every two years, you pay the custom plate fee again if you want to keep the plate.

After the DMV approves your custom plate order, the plates are manufactured and mailed to you. This process usually takes 4 to 8 weeks. During this time, you will receive temporary registration documents that you can display in your vehicle window. Do not remove your old plates until the new custom plates arrive.

If you need your custom plates faster, some DMV offices offer rush processing for an additional fee, though this is not available at all locations. Call your local DMV office to ask whether rush processing is an option in your area and what the extra cost is.

Restrictions on custom plate combinations

California reserves certain combinations and will not allow you to order them. The DMV permanently blocks plates that spell profanity, slurs, or other offensive language, even if the combination uses numbers creatively (like "A55H0L3"). The DMV also reserves plates that are historically significant, such as those assigned to government vehicles or law enforcement.

Your custom plate can be up to seven characters long and can include letters, numbers, or both. Spaces and special characters like hyphens or periods are not allowed. The DMV does allow you to use a single space between characters, which counts as one of your seven characters.

If you choose a combination that the DMV rejects, you will be told why during the reservation process. You can then choose a different combination and try again. There is no limit to how many times you can search and reserve different combinations.

How to order custom plates online or by mail

Online ordering is the fastest route. Go to dmv.ca.gov, search for "custom plates," and follow the link to the custom plate reservation system. You will enter your desired combination, check availability, and reserve it if it is available. You will then need to complete your vehicle registration or transfer in the same session. The DMV will send you a confirmation email with your reservation number.

After you reserve your plate online, you must complete your registration or transfer within 30 days. You can do this online if you are registering a new vehicle or transferring registration from another state. If you are transferring a plate from an existing California vehicle, you may need to visit a DMV office or mail in documents, depending on your situation.

Mail ordering takes longer but works if you prefer not to go online. read the process for Duplicate or Replacement License Plates (Form DL 44) from dmv.ca.gov, fill it out with your desired custom plate combination, and mail it to the address listed on the form along with your registration documents and payment. Include a check or money order for the custom plate fee plus your registration fees. Mail processing typically takes 6 to 10 weeks total.

In-person ordering at a DMV office lets you reserve your plate and complete registration the same day. Bring your vehicle registration documents, proof of residency, and payment. A DMV representative will check your combination, reserve it if available, and process your registration. You will still wait 4 to 8 weeks for the plates to arrive by mail.

Transferring a custom plate to a different vehicle

Once you own a custom plate, you can move it to a different vehicle without losing it. To transfer a custom plate, you must submit a Notice of Transfer and Release of Liability (Form REG 138) along with your new vehicle's registration documents and proof of ownership. You can do this online, by mail, or in person at a DMV office.

When you transfer a custom plate, you do not pay the custom plate fee again — you only pay the standard registration transfer fee. However, you must keep renewing the plate every two years, and each renewal includes the custom plate surcharge. If you let your registration lapse and do not renew for more than a few years, the DMV may release your custom plate back into the available pool.

If you want to keep a custom plate but are selling or trading in your vehicle, you can request that the DMV hold the plate for you while you arrange a new vehicle. Contact your local DMV office to ask about plate hold procedures in your area, as policies vary slightly by location.

Scam alerts and safety information

Be cautious of websites that claim to sell California custom plates or to may provide you a specific combination. The only official source for California custom plates is the DMV itself. Third-party websites that offer "custom plate services" are either scams or middlemen who charge you extra money to do what you can do directly and for free through dmv.ca.gov.

Never send money or personal information to anyone claiming to reserve a custom plate for you outside the official DMV channels. Scammers sometimes advertise on social media or search results with names that sound official, like "California DMV Services" or "CA Plate Reservations," but these are not affiliated with the state.

If you receive an email or text claiming to be from the DMV asking you to verify your custom plate reservation or pay a fee, do not click any links or reply. The DMV does not contact you by unsolicited email or text to collect payment. Go directly to dmv.ca.gov or call 1-800-777-0133 to verify any communication you are unsure about.

Frequently Asked Questions

Can I keep my custom plate if I move out of California?

No. Custom plates are issued only for vehicles registered in California. If you move to another state and transfer your vehicle registration there, you must surrender your California custom plate and accept the new state's plate format. You cannot transfer a California custom plate to an out-of-state vehicle.

What happens if someone else orders the custom plate I want before I finish my registration?

This is unlikely because the DMV holds your reservation for 30 days once you reserve it online. During that 30 days, no one else can order that combination. If your reservation expires because you did not complete your registration in time, the plate becomes available again and someone else could order it. You can always search for a different combination and reserve that instead.

Do I have to renew my custom plate every time I renew my registration?

Yes. Every two years when your vehicle registration renews, you must pay the custom plate fee again if you want to keep the plate. If you do not renew your registration or you choose not to pay the custom plate fee at renewal time, the plate is released and becomes available for someone else to order.

Can I order a custom plate for a vehicle that is not yet registered?

You can reserve a custom plate combination online, but you must complete your vehicle registration within 30 days of the reservation. You cannot reserve a plate without starting the registration process. If you do not have your vehicle documents ready yet, wait until you do before you reserve the plate.

What if the custom plate I want is taken but I see it on another vehicle?

That vehicle's owner has already ordered and is using that plate. The DMV does not release plates that are currently in use. Your only option is to choose a different combination. If you believe a plate is being used illegally or was obtained through fraud, you can report it to the DMV, but this does not make the plate available for you to order.
