Know which document or plate is missing before you apply
Determine whether the problem involves the registration certificate, one or both plates, the annual validation sticker, or an ownership title. Each document serves a different function and has a different replacement route. Read WYDOT's vehicle-services overview so the request reaches the county treasurer for ordinary registration credentials or the county clerk for a title.
Record the VIN, full plate number, vehicle year and make, registered owner, expiration, and what happened to the item. If a sticker or plate was damaged during installation, retain it for the issuing office. A detailed description helps distinguish an ordinary missing-document request from a plate-number change, ownership correction, or expired-registration problem.
Contact the appropriate registration office
Use the county treasurer contact list and start with the office holding the registration. Section 31-2-212 of the motor-vehicle statutes provides replacement authority for lost, mutilated, or destroyed credentials through a county treasurer or the department for credentials it issued. Explain the original issuing program if the plate is unusual.
Confirm the office's accepted application method, identification evidence, payment, and delivery arrangements. County procedures and special-plate requirements can differ. Do not mail an original title merely to replace a registration card unless the office specifically requires ownership evidence for an additional issue; identify the transaction accurately before sending irreplaceable documents.
Check whether the underlying registration is still valid
A replacement restores a missing or damaged credential for the existing record; it does not automatically extend the registration period. Review the expiration through the county vehicle-licensing service and ask whether renewal must be completed at the same time. The issued replacement should reflect the correct currently authorized term.
If the vehicle changed owners or the plates were moved, correct the record rather than requesting a duplicate of an inaccurate assignment. The title office's guidance explains the separate ownership transaction. A plate physically attached to a replacement vehicle is not sufficient evidence that the county has approved a reassignment.
Get a duplicate registration certificate
The statutory charge for a duplicate certificate of registration is $4. Provide the plate and vehicle information needed to locate the record and follow the county's identification requirements. Keep the resulting certificate available with the vehicle as required, and check that it describes the correct VIN and current assigned plate.
The county registration checklist notes that an existing plate number can help locate a vehicle when a renewal card or prior registration is unavailable. That assistance does not erase the obligation to obtain the required credential. Ask how the duplicate will be delivered and whether any authorized temporary evidence is available for an immediate travel need.
Request a replacement annual validation sticker
The statutory fee for replacement validation stickers is $6. Explain whether the sticker was lost, destroyed, improperly attached, or never received after an earlier transaction. Supply the payment or renewal details when a mailed item is missing so the office can identify whether a replacement or completion of the original transaction is needed.
Follow the county's placement instructions when the new sticker arrives. The optional WYDOT recognition decals are separate products and do not establish annual registration validity. Do not substitute a decorative decal, reuse another vehicle's sticker, or assume that the presence of an older expiration sticker proves that a pending renewal has been completed.
Choose a new plate number or an eligible reproduction
The MV-405 application distinguishes a new plate with the next available consecutive number from a duplicate reproducing an eligible existing number or combination. The new-number charge is $8. Reproduction costs $30 and is limited to prestige plates, qualifying specialty types, and the county's preferred-number series.
The treasurer determines the preferred-number series within the published limit of 9,999. Obtain county approval for the requested reproduction before assuming the same combination can be remade. The application asks for the reason, county, plate type, combination, VIN, expiration, owner, and mailing details, so complete those fields consistently with the registration record.
Understand the restriction on lost or stolen same-number plates
MV-405 states that when the original plates cannot be surrendered because they are lost or stolen, reproduced same-number plates cannot be displayed until the validation stickers on the original plates expire. This restriction matters even if the owner wants to preserve a familiar personalized or preferred combination.
Discuss a new-number replacement and any available operating arrangement with the treasurer instead of assuming that ordering a reproduction allows immediate use. Provide accurate loss or theft information. If the plates were stolen or later appear associated with an incident, retain the agency and law-enforcement records relevant to identifying when the credentials left the owner's control.
Submit MV-405 through the county and surrender damaged items
The current form directs the applicant to mail the completed application and fee to the county treasurer in the county of registration. It includes the treasurer's approval section and the applicant's affidavit. Follow the receiving office's instructions for completing any official section rather than signing on behalf of the approving officer.
Damaged or mutilated plates must be surrendered when the new plates are received, and the form addresses surrender of the original registration and plates upon issuance. Keep a record of the replacement number and new certificate. Do not continue displaying the superseded plate on another vehicle or retain it for an unauthorized future assignment.
Route embossed and specialty replacements correctly
MV-405 expressly excludes replacement of lost, damaged, or mutilated embossed plates. Use the embossed-plate program and its MV-145 application, including the required registration copy and charge. The agency publishes a production period for these plates, so consider how the vehicle will remain properly credentialed while the request is processed.
Consult the specialty-plate overview for a design issued through a particular state program. Prestige plates also have vehicle-type, combination, county-delivery, and surrender rules that can affect a replacement. Verify the actual plate category before sending a fee calculated for a different credential or assuming an ordinary county-stock plate preserves the original combination.
Do not confuse a missing title with a missing registration
A title replacement goes through the clerk that issued the original Wyoming title. The duplicate-title application requires the specified ownership information and sworn signature, and the title fee is separate from the registration-card replacement charge. Use the county clerk directory when the original title county differs from the current registration location.
If a lender holds the ownership certificate, establish that fact before describing the document as lost. A new registration card does not release a lien, change owners, or replace a title needed for a sale. Address those issues with the clerk and secured party rather than requesting multiple credentials in the hope that one will resolve the ownership record.
Verify delivery and lawful operation before the next trip
When the replacement arrives, compare the VIN, plate number, owner, and expiration and attach the issued items as directed. The current county online-renewal instructions warn that a payment receipt is not itself renewal proof; similarly, do not assume a replacement order confirmation supplies every credential required for operation. Ask the issuing office about the specific record and travel circumstances.
Keep the application and payment evidence until the correct replacements are received. A novelty plate cannot fill the gap, and a borrowed plate creates a different registration problem. Arrange lawful transport or delay the trip if the required plates, validation, or registration evidence cannot be obtained in time for the planned road use.
Frequently Asked Questions
What is the Wyoming duplicate registration certificate fee?
The statutory charge is $4 for a duplicate registration certificate, with any additional delivery or transaction cost determined by the issuing office.
How much is a replacement annual validation sticker?
Wyoming’s miscellaneous-fee statute lists $6 for new validation stickers replacing lost, mutilated, or destroyed originals.
What is the difference between an $8 and a $30 plate replacement?
The $8 transaction issues the next available new number, while $30 reproduces an eligible prestige, specialty, or preferred-series number or combination.
Can I immediately display a same-number replacement after my plates were stolen?
MV-405 prohibits display of reproduced same-number plates until the original plates’ validation stickers expire when the lost or stolen originals cannot be surrendered.
Is MV-405 used to replace embossed plates?
Embossed replacements require the separate MV-145 application and embossed-plate procedure instead of MV-405.
Will replacing my registration card also replace a lost title?
The ownership title is a separate credential handled by the original issuing county clerk, with its own application, affidavit, and fee.
