Idaho lets you customize your license plate through the Department of Motor Vehicles, but the process has specific rules about what text you can use, how long it takes, and what it costs
A personalized plate in Idaho starts with choosing your custom text — up to six characters for most plate types — then submitting your request through the DMV. The state checks whether your text is available and whether it meets content rules. If approved, you'll pay a one-time personalization fee on top of your regular registration renewal cost. The whole process typically takes two to four weeks from submission to receiving your plate in the mail.
You don't have to renew your registration to get a personalized plate; you can request one at any time during your registration period. However, the plate itself arrives separately from your regular registration documents, so plan for a gap between when you order and when you can legally display it.

- The Idaho DMV checks your requested text against a list of prohibited words and phrases before approving your plate.
- You can request a personalized plate online through the Idaho DMV website, by mail, or in person at any DMV office.

What text you can and cannot use on an Idaho personalized plate
Idaho prohibits personalized text that is obscene, offensive, or that impersonates a government agency or emergency vehicle. The DMV also blocks requests that contain slurs, sexual references, or text that could be mistaken for an official state or federal seal. Profanity in any form — including creative spelling or symbol substitution — is rejected.
Text that references illegal activity, promotes violence, or targets a specific group is also denied. The DMV reviews each request individually, so borderline cases may be rejected even if they don't fit neatly into a single category. If your request is denied, you receive a letter explaining why and you can submit a new request with different text.
Numbers and letters can be mixed freely within your six-character limit. Spaces and punctuation marks are not allowed on Idaho personalized plates.
How to request a personalized plate online or by mail
The fastest route is the Idaho DMV website. Go to isp.idaho.gov, find the personalized plate section, and enter your desired text to check availability when ready. If it's available, you can complete the request form right there, provide your vehicle information and current registration number, and pay the $25 personalization fee by credit or debit card. You'll receive a confirmation number when ready.
If you prefer to explore by mail, read the personalized plate request form from the DMV website or pick one up at any DMV office. Fill in your desired text, vehicle details, and current registration information. Include a check or money order for $25 made payable to the Idaho State Police. Mail the form to the address listed on the form — typically the DMV headquarters in Boise. Processing takes longer by mail because the DMV must manually check availability and review your text.
You can also walk into any DMV office in Idaho and request a personalized plate in person. Bring your vehicle registration, driver's license, and payment. The staff will check availability on the spot and submit your request when ready if your text is available and approved.
What happens after you submit your request
Once the DMV receives your request, they verify that your text hasn't been claimed by another vehicle and that it meets content rules. This review typically takes three to five business days. If approved, your plate is manufactured and mailed to the address on your registration. If denied, you receive a letter explaining the reason and you can submit a new request.
Your new plate arrives in a padded envelope with instructions for installation. You must physically install the plate on your vehicle before you can legally display it — you cannot use your old plate once your personalized plate has been issued. Keep your old plate; some owners frame it or store it, but you're not required to return it to the state.
The $25 personalization fee is a one-time charge. When you renew your registration in future years, you pay only the standard registration renewal fee; the personalization fee does not repeat. Your personalized plate remains yours as long as you own the vehicle and keep your registration current.
Personalized plates and vehicle registration renewal
You can request a personalized plate at any point during your registration period — you don't have to wait until renewal. However, many people order a personalized plate when they renew registration because they're already interacting with the DMV. If you order mid-cycle, your new plate arrives separately from your registration renewal documents.
When your registration expires and you renew, your personalized plate stays with your vehicle. You straightforward renew your registration as normal and pay the standard renewal fee. The personalization does not expire or require renewal; it's a permanent modification to your vehicle's registration record.
If you sell your vehicle, the personalized plate does not transfer to the new owner. You can request to keep the plate and transfer it to a different vehicle you own, but this requires a separate request to the DMV. Most people straightforward let the plate stay with the sold vehicle.
Cost breakdown and payment options
The personalization fee is $25, paid once when you request the plate. This is separate from and in addition to your regular registration renewal fee, which varies based on your vehicle type and weight. If you're renewing registration at the same time you order a personalized plate, you'll pay both fees together.
Payment methods depend on how you submit your request. Online requests accept credit and debit cards. Mail-in requests require a check or money order. In-person requests at a DMV office accept cash, check, debit card, and credit card — specific payment methods may vary by location, so call ahead if you have a preference.
There are no refunds if you change your mind after your plate is manufactured. If you want to switch to a different personalized text, you must request a new plate and pay the $25 fee again. Your old personalized plate cannot be reused or transferred.
What to do if your requested text is denied or already taken
If the DMV denies your request because the text violates content rules, you receive a letter explaining the specific reason. You can then submit a new request with different text. There's no limit to how many times you can request a personalized plate, but each request costs $25.
If your text is already claimed by another vehicle, the DMV notifies you and you can choose new text. Some people try variations — for example, if "IDAHO1" is taken, you might try "IDAHO2" or "IDHO1" — but remember you're limited to six characters total. You can also check availability before submitting by using the online search tool on the DMV website.
If you're unsure whether your text will be approved, you can call the Idaho DMV directly at the number listed on their website and ask a staff member to review it before you pay. This can save you the $25 fee if your text is likely to be denied.
