Yes, you can change your license plate number, but the process and cost depend on your state and the reason you want the change

Most states allow you to request a new plate number through your Department of Motor Vehicles (DMV) or equivalent agency. The change is usually straightforward if you want a different number for personal preference — you pay a fee, submit a form, and receive new plates in the mail. However, some states have restrictions: a few require you to keep the same number for a set period after registration, and some charge higher fees for vanity plates or special sequences. A handful of states make the process difficult or impossible without a specific reason like a security concern or a plate that was damaged.

The cost ranges from roughly $20 to $100 depending on your state and plate type. Standard replacement plates cost less than vanity plates (custom numbers or letters). Some states charge the same fee whether you're replacing a damaged plate or requesting a new number by choice; others charge more for a voluntary change. A few states include the fee in your regular registration renewal, so you may not pay extra if you time the request correctly.

Key Takeaways

  • Contact your state's DMV to learn whether you can change your plate number and what the fee is, since rules vary significantly by state.
  • You will need your current vehicle registration, driver's license, and proof of vehicle ownership to request a plate change.
  • Standard plate number changes usually take two to four weeks to arrive by mail, though some states offer faster service at a DMV office.
  • Some states restrict how often you can change your plate number or require you to keep the same number for a minimum period after registration.
  • Vanity plates (custom letters or numbers) cost more than standard replacements and may have a longer wait time.

How to request a new plate number through your DMV

Start by visiting your state's DMV website or calling the main office to confirm the process and current fee. Most states let you request a change online, by mail, or in person at a local DMV office. If you go online, you'll typically enter your vehicle information, current plate number, and the reason for the change (if the state asks). Some states have a dropdown menu with options like "personal preference," "damaged plate," or "security concern." Choose the option that fits your situation honestly — states that ask this question use it to determine whether you pay a standard fee or a higher one.

Gather your documents before you start: your current vehicle registration, a valid driver's license, and proof of ownership (the title or a recent registration notice). If you're requesting the change by mail, photocopy these documents and send them with the completed form. Include a check or money order for the fee unless the state processes payment online. Mail everything to the address listed on the DMV website, not to a local office, unless the site specifically directs you otherwise.

After you submit, expect to wait two to four weeks for new plates to arrive by mail. Some states offer expedited service at a DMV office for an additional fee — you can pick up plates the same day or within a few days. If you need the plates urgently, call your DMV to ask whether this option is available and what it costs.

Restrictions and waiting periods by state

A few states impose a waiting period before you can change your plate number. For example, some require you to keep the same number for at least one year after registration, or they limit you to one change per registration period. These rules exist to reduce administrative work and prevent people from cycling through numbers constantly. Check your state's specific rules on the DMV website — search for "plate number change" or "new plate request" on the site.

A small number of states make voluntary plate changes difficult or charge significantly higher fees to discourage them. If your state falls into this category, the DMV website will be clear about the cost and process. In rare cases, a state may require you to provide a reason (such as a security threat or a plate that was damaged or lost) to change your number. If you straightforward want a different number for personal preference and your state requires a reason, contact the DMV directly to ask whether personal preference qualifies.

Vanity plates and custom numbers

If you want a specific combination of letters and numbers rather than a random assignment, you're requesting a vanity plate. These cost more — typically $50 to $100 per year in addition to your regular registration — and the process takes longer because the DMV has to check whether your requested combination is available and doesn't violate content rules.

Most states reject vanity plate requests that spell profanity, slurs, or combinations that could be offensive. The rules vary by state, so a plate that's rejected in one state might be approved in another. When you request a vanity plate, the DMV will tell you within a few days whether your choice is available. If it's not, you can request a different combination. Once approved, vanity plates usually arrive within two to four weeks, the same as standard plates.

What happens to your old plate number

When you receive new plates, your old number is deactivated and returned to the DMV's pool. You don't have to physically return the old plates in most states — the DMV removes them from your account when you register the new ones. However, some states ask you to mail in the old plates or turn them in at a DMV office. Check your state's instructions when you receive your new plates; they'll say whether you need to return the old ones.

Once your old number is deactivated, another vehicle owner can request it in the future. This usually takes several months or longer, so the number won't be reassigned when ready. If you're concerned about someone else using your old number, this delay provides some protection, though in practice it's not a major security issue.

Changing your plate number during registration renewal

If your vehicle registration is coming up for renewal, you can often request a new plate number at the same time. This can save you money in some states because the plate fee is bundled with the renewal fee, or because you avoid paying a separate change fee. When you renew your registration online or by mail, look for an option to request a new plate number. If you don't see one, call the DMV to ask whether you can add the request to your renewal.

Timing this correctly means you'll receive your new registration and new plates together, usually within two to four weeks. If you request the change outside of your renewal period, you'll pay a separate fee and wait for the plates separately from your registration documents.

Frequently Asked Questions

Can I keep my old plate number if I sell my car?

This depends on your state. Some states let you transfer your current plate number to a new vehicle you own, while others require you to get a new number when you register a different car. A few states offer a "plate retention" program where you can keep a number you're attached to and transfer it between vehicles. Contact your DMV to learn whether your state offers this option.

What if I want a plate number that's already taken?

You cannot request a number that's currently assigned to another vehicle. If you want a specific combination of letters and numbers, the DMV will check availability when you submit your vanity plate request. If it's taken, you'll be told when ready and can request a different combination.

Do I have to change my plate number if I move to a different state?

Yes. When you register your vehicle in a new state, you must get new plates with that state's format and design. You cannot keep plates from your previous state. The new state's DMV will issue plates as part of your registration process.

How much does it cost to change my plate number?

Standard plate changes typically cost $20 to $50, though some states charge up to $100. Vanity plates cost more — usually $50 to $100 per year on top of your regular registration. Check your state's DMV website for the exact fee, as it varies widely.

Can I change my plate number online?

Most states allow you to request a plate change online through their DMV website. A few states require you to visit an office in person or mail in a form. Check your state's DMV website to see which methods are available and whether you can pay online or need to send a check.
