Getting a Wyoming VIN inspection

Determine the reason for the inspection

A VIN inspection connects a physical vehicle with its ownership record. Wyoming requires that connection in several title transactions, including vehicles titled or registered outside the state, homemade or reconstructed vehicles, kit vehicles, and bonded-title applications. The current requirements appear in section 31-2-103 of Wyoming's motor vehicle statutes. An inspection is a particular identification step, rather than a general promise that the vehicle is mechanically sound or free of every ownership dispute.

Start with the county clerk that will process the title and describe the vehicle's history. Tell the office whether the number is readable, whether the vehicle is in Wyoming, and whether its major components came from different vehicles. A routine out-of-state title verification and an application for a new state-assigned number need different paperwork. Identifying the correct route first avoids paying for an inspection that does not answer the question the title office must resolve.

Use an authorized inspector for an ordinary title

For a vehicle physically in Wyoming, current law permits a Wyoming law enforcement officer to certify the inspected number. A licensed Wyoming dealer can also perform the specified title inspection for a vehicle in that dealer's inventory or possession, subject to the applicable dealer requirements. That authority does not mean any dealer must inspect a privately owned vehicle on demand. Arrange the visit and identify the form before bringing a vehicle to a business or police facility.

The Wyoming title and VIN inspection application provides space for the identifying information and certification. Bring the existing title or other ownership evidence so the inspector can compare documents with the physical number. Ensure the VIN is accessible and readable without unsafe dismantling. If a number differs from the paperwork, have the discrepancy documented and investigated rather than copying the title number into a form as though the physical inspection confirmed it.

Address vehicles located outside Wyoming

Section 31-2-103 provides a separate option when the vehicle is not in Wyoming. It permits certification on a department-approved form by specified authorized law enforcement officers, a commissioned officer at a federal military installation, or another person authorized by law. Submit the completed inspection to the county handling the title along with the required inspection fee. Confirm the inspector and form with that county before arranging an out-of-state appointment.

County instructions can clarify practical details. Crook County's vehicle-title page, for example, identifies the title and inspection fees and explains the documentation for incoming vehicles. Keep the receipt when an inspection fee is paid to law enforcement so the clerk can reconcile payment correctly. Do not infer that an out-of-state safety certificate or emissions test fulfills Wyoming's VIN certification requirement; the required document must establish the identifying number in the accepted form.

Recognize when a replacement number is necessary

Use WYDOT's assigned-VIN program when the actual identification problem requires a state number. The February 2026 eligibility explanation includes missing VINs, vehicles assembled with multiple VINs, and modifications that remove a numbered component or introduce a different numbered component. Homemade trailers and factory trailers whose identifying label is missing may also need this process. Describe the actual circumstances instead of selecting whichever donor VIN is easiest to read.

Some changes only require a record correction. WYDOT specifically distinguishes a body-style conversion that retains its VIN: the owner should have the clerk and treasurer update the body code rather than assume a new number is mandatory. A boat hull identification number belongs to the Game and Fish watercraft program, while a boat trailer's vehicle number belongs to the vehicle process. Keeping the boat and trailer documents separate prevents an ownership application from being attached to the wrong asset.

Prepare the state-assigned VIN application

The MV-401 assigned-number application is for Wyoming residents and requires a completed vehicle or trailer, ownership evidence, a photograph, and the $20 application fee. WYDOT's application instructions explain the sequence and the required statement of facts. The initial law enforcement inspection must record that no VIN was found or list every VIN found, with the locations and officer information. A trailer made from a pickup box has a specified exception to that initial inspection step.

Use the assigned-VIN program's inspector instructions rather than extending the ordinary dealer-inspection rule to this application. Its guidance calls for Wyoming law enforcement and requires a signed explanation when circumstances make an out-of-state law enforcement inspection necessary. Ask WYDOT about that situation before submitting an incomplete packet. Do not arrange a new number simply to avoid a disputed title, existing lien, or salvage brand; each of those issues needs its own resolution.

Establish ownership of the components

Send original titles, manufacturer's statements, or certificates of origin when the application requires them, properly assigned with liens released. For bills of sale, WYDOT directs applicants to send copies and retain the originals for the county. Receipts should connect each major component to its source. If parts were gifts or came from property already owned, a signed factual statement must still explain where, when, and from whom they were obtained.

The assigned-VIN questions and answers explains how to document missing papers and establish the year and make. A homemade trailer normally uses its completion year, while an assembled motor vehicle uses the oldest major component under the stated rules. The year cannot simply be entered as unknown. Include a photograph of the finished vehicle and any supporting evidence needed to substantiate the description. A state title search can help investigate prior records, but does not replace proof of lawful acquisition.

Stamp the assigned number and obtain verification

After approval, follow the state-assigned VIN process in order. WYDOT supplies a certificate assigning the number; it does not issue the county title. The assigned number must be marked on the vehicle in the specified manner and location. Read the instructions for the particular frame or trailer configuration rather than stamping a convenient removable panel. The characters must remain clear enough for law enforcement to verify.

A second law enforcement inspection confirms the assigned number has been applied. WYDOT lists $10 for this inspection and $15 for the subsequent title, in addition to the $20 assignment fee. The initial pickup-box exception does not eliminate the final verification of the newly marked number. Present the completed assignment certificate and original supporting ownership documents to the county clerk. The county may also request a weight slip, even though the assigned-number application itself does not require one.

Finish the related title requirements

A successful identification inspection leaves other title conditions to be addressed. For a repaired salvage vehicle, follow the separate salvage and rebuilt instructions and rebuilt decal application; the officer may need to verify both the identifying number and the installed rebuilt decal. For uncertain ownership, review the bonded-title requirements with the clerk. Neither procedure should be collapsed into a routine VIN check merely because an officer examines the vehicle during the process.

Complete the tax payment or exemption receipt required by the county vehicle-tax process, then obtain the title and proceed to the county treasurer for registration. Before leaving either office, compare the issued VIN, make, year, body type, and owner information against the approved documents. A transcription error is easier to correct with the full application packet available. Retain the inspection and assignment records with the vehicle's history for future sales, insurance questions, and ownership verification.

Frequently Asked Questions

Is a Wyoming VIN inspection a mechanical safety inspection?
The VIN process verifies identity for the transaction. It does not certify the overall condition, repair quality, or safety of the vehicle.

Can a Wyoming dealer perform my inspection?
The ordinary title-inspection statute allows licensed Wyoming dealers to inspect vehicles in their inventory or possession. The state-assigned VIN program has separate law enforcement requirements.

What if the vehicle is currently outside Wyoming?
Ask the receiving county about the approved form and inspector options under section 31-2-103 before arranging the inspection where the vehicle is located.

Will WYDOT send a title with an assigned number?
WYDOT provides the assignment certificate. After marking and verification, the county clerk issues the title upon satisfaction of the remaining requirements.

Do I need ownership evidence for parts received as gifts?
Gifted components still need a documented source. Follow MV-401 and provide the required statements and available ownership records.

Does changing a trailer body always require another VIN?
WYDOT distinguishes body-style changes that retain the original VIN. The clerk and treasurer may update the body code when the number remains valid instead of assigning a replacement.
