License plates are issued by your state's motor vehicle department, not the federal government, so the format, cost, and rules differ depending on where you register your vehicle

Every state runs its own registration system and designs its own plates. The format — how many letters, numbers, and what order they appear in — is set by each state's Department of Motor Vehicles (or equivalent agency). Some states use a format like ABC-1234, others use 1ABC-234, and a few use entirely different patterns. The cost of a plate, how often you renew it, and what happens when you move all depend on which state issued yours.

When you register a vehicle in a state, that state's DMV assigns you a plate number and mails the physical plate to your address. If you move to a new state, you do not automatically get a new plate — you must register your vehicle in the new state and surrender the old one. The old plate goes back to the issuing state's DMV.

Key Takeaways

  • Each state designs its own plate format and assigns numbers through its DMV, so the appearance and numbering system vary widely by location.
  • Plate costs range from under $20 to over $200 depending on the state and whether you choose a standard or specialty plate.
  • Most states require you to renew your plate every four to six years, though some require annual renewal as part of vehicle registration.
  • Moving to a new state means registering your vehicle there and getting a new plate; you cannot keep an out-of-state plate permanently.
  • Specialty plates — supporting causes, displaying college logos, or showing military service — cost more but are available in most states.

How states assign and format plate numbers

Each state's DMV maintains a database of all registered vehicles and assigns plate numbers sequentially or through a system designed to avoid duplicates within that state. The format itself is a state choice. Some states use a pattern like "ABC 1234" (three letters, four numbers), while others use "1 ABC 2345" (one number, three letters, four numbers). A few states use vanity-style formats where you can request a custom combination if it is available.

The format sometimes changes when a state runs out of available combinations. For example, if a state has used all possible plates in its current format, the DMV will switch to a new format with more available combinations. This is why older vehicles sometimes have plates that look different from newer ones registered in the same state.

Your plate number is tied to your vehicle's Vehicle Identification Number (VIN) and your registration record. The DMV uses this connection to track ownership, insurance status, and whether your registration is current. When you renew your registration, you typically keep the same plate number unless you request a new one or the plate is damaged.

Plate renewal timelines and costs by state

Renewal cycles vary by state. Most states require plate renewal every four to six years, though some require annual renewal tied to your vehicle registration anniversary. When you renew, you usually receive a new physical plate in the mail, or in some states, just a sticker that goes on your existing plate.

The cost of a standard plate ranges from under $20 in some states to over $200 in others. States with lower costs include South Carolina, Georgia, and Wyoming. States with higher costs include New York, California, and Massachusetts. The cost often includes the registration fee, so the plate itself may be only part of what you pay. Some states charge a separate plate fee on top of registration.

If your plate is damaged, lost, or stolen, you can request a replacement from your state's DMV. Replacement plates usually cost $10 to $30 and take one to two weeks to arrive by mail. If you need a plate when ready, some states allow you to pick one up in person at a DMV office.

Specialty and vanity plates

Most states offer specialty plates that support causes, display college logos, military service, or other affiliations. These plates cost more than standard plates — typically $25 to $100 extra per year — but a portion of the fee goes to the organization or cause the plate supports. For example, a state wildlife plate might cost $50 total, with $20 going to the state wildlife fund.

Vanity plates let you request a custom combination of letters and numbers instead of accepting a random assignment. These also cost more, usually $50 to $100 extra per year. Availability depends on what combinations are already taken in your state. You request a vanity plate through your state's DMV website or in person, and the DMV tells you whether your choice is available.

Specialty and vanity plates renew on the same schedule as standard plates. If you choose a specialty plate and later want to switch back to a standard plate, you can do so at your next renewal or by requesting a change in person at the DMV.

What happens to your plate when you move states

You cannot keep an out-of-state plate after you move and establish residency in a new state. Most states require you to register your vehicle within 30 to 90 days of moving there. When you register in the new state, you receive a new plate from that state's DMV, and you must return or destroy the old plate according to your previous state's rules.

Some states allow you to keep an out-of-state plate temporarily if you are a student or military member stationed there. You typically need to provide proof of your status and a document showing your home address is still in the original state. This exception usually lasts one to two years, after which you must register in the state where you are living.

If you move back to a state you previously lived in, you do not automatically get your old plate number back. Plate numbers are reassigned once a vehicle is unregistered, so your old number may have been given to another vehicle years ago.

Expired, lost, and stolen plates

Driving with an expired plate is illegal in every state and can result in a traffic citation. If your registration renewal notice arrives in the mail, renew it before the expiration date shown on your current plate. Most states send renewal notices 30 to 60 days before expiration, but if you do not receive one, contact your DMV to check your renewal date.

If your plate is lost or stolen, report it to your state's DMV and request a replacement. You will receive a new plate with a different number. Some states require you to file a police report for a stolen plate, so check your state's DMV website for the specific steps. A replacement plate usually arrives within one to two weeks.

If you find a plate that is not yours, you can turn it in to any police department or DMV office. Do not attempt to use it or keep it — plates are registered to specific vehicles and owners, and using someone else's plate is illegal.

Personalized and commemorative plates

Beyond vanity plates, many states offer commemorative plates that mark military service, professional licenses, or other achievements. A military veteran plate, for example, displays a veteran designation and may cost $50 to $75 per year. A professional license plate (for doctors, lawyers, or engineers) works similarly. These plates are available only to people who meet the state's criteria for that designation.

Some states also offer plates that commemorate historical events, support charitable causes, or display state symbols. These are available to any vehicle owner and work like specialty plates — you pay a higher fee, and part of it goes to the supporting organization. The design and availability of these plates change over time as states add or retire them.

Frequently Asked Questions

Can I request a specific plate number?

Most states allow vanity plate requests, where you suggest a custom combination. The DMV checks whether it is available in your state. If it is taken, you can request another combination. Vanity plates cost extra and require annual or biennial renewal like standard plates.

What do I do if my plate is damaged or faded?

Contact your state's DMV and request a replacement plate. You can usually do this online, by mail, or in person. Replacement plates cost $10 to $30 and take one to two weeks by mail. Some DMV offices allow same-day pickup if you visit in person.

Do I have to get a new plate when I renew my registration?

It depends on your state. Some states issue a new physical plate every renewal cycle; others issue a sticker that goes on your existing plate. Check your state's DMV website or your renewal notice to see what to expect.

What if I move to a new state but keep my vehicle registered in my old state?

Most states require you to register your vehicle where you live within 30 to 90 days of moving. Keeping an out-of-state registration is generally illegal unless you are a student or military member with an exception. Violating this can result in fines and registration suspension.

Can I transfer my plate to a different vehicle?

No. Plates are tied to specific vehicles through their VIN. If you buy a new vehicle, you register it separately and receive a new plate. Your old plate is retired when you unregister the old vehicle.
