WYDOT Motor Vehicle Services in Cheyenne issues Wyoming apportioned plates. A first-time registrant applies by mail or in person with proof of a Wyoming established place of business or residency; later transactions and quarterly-staggered renewals run through the Commercial Carriers of Wyoming System (CCOWS). Fees are apportioned by the fleet's distance in each jurisdiction, and Wyoming's own share is a county fee on factory price plus a weight-based state fee.
Wyoming IRP administration
- Process
- New accounts apply by mail or in person with the Wyoming IRP application (CC-111) and Schedule A/C; WYDOT encourages mailing so it can check the packet. Credentials cannot issue until every required document is in and the billing notice is paid in full.
- Fee structure
- Each jurisdiction's full-year fee is multiplied by the fleet's share of distance there, using actual distance from the reporting period (the 12 months before July 1 of the preceding year) or, for a new fleet, the Average Per Vehicle Distance Chart.
- Fees: wyoming share
- The Wyoming portion is a county fee of 15 dollars plus 3 percent of factory price and special equipment, multiplied by 0.60 in the first year of service, stepping down to 0.15 from the sixth year, plus a state fee by gross weight (for example 907.50 dollars at 78,001 to 80,000 pounds). Trailers are not apportioned: Wyoming-based trailers pay a yearly county plate fee on value and age.
- Fees: payment
- Pay by cash, check, money order, credit card (3.5 percent processing fee) or e-check (2.00 dollar fee), payable to WYDOT-IRP.
- Fees: refunds
- No refunds unless paid by mistake (W.S. 31-18-406(d)); apportioned fees may be transferred to a replacement vehicle on sale, destruction, lease termination or ownership transfer, within the same registration year.
- Cab card
- The cab card is the registration and authority to operate in each jurisdiction and must be carried in the power unit at all times. Under Full Reciprocity every IRP jurisdiction is listed on every Wyoming cab card, so apportioned vehicles do not need trip permits.
- Cab card: check on receipt
- Verify VIN, weights by jurisdiction, name, expiration, USDOT number (including the carrier responsible for safety if leased), and that the plate number matches; report errors to the IRP Section at 307-777-4829.
- Process: system
- Commercial Carriers of Wyoming System (CCOWS), https://ccows.dot.state.wy.us/WYEnterprise/
- Process: documents
- Proof of a valid EIN (no SSN), Secretary of State good standing for an LLC or corporation, an active USDOT number with interstate authority and an MCS-150 updated within two years, the three annual forms (Proof of Established Place of Business or Residency, Agreement to Prepare and Maintain Records, Safety Regulations), Wyoming Schedule B distance form if previously apportioned, a power of attorney for any service provider, Schedule A/C, IRS Form 2290 for vehicles of 55,000 pounds or more, proof of insurance, a title copy for each vehicle, and lease agreements if running under another carrier's USDOT number.
To work through your mileage inputs, calculate each jurisdiction’s share of your fleet miles. The estimator apportions any full-year fees you enter; it does not contain state fee schedules or issue an official quote.
More Wyoming IRP rules
- Temporary credentials: summary
- A temporary tag (Temporary Registration Authority) can be issued for 45 days on a private-party purchase or 60 days on a dealer purchase, only for accounts in good standing; the full year's fee is owed even if the sale falls through, and Wyoming issues no temporary tags for trailers. A 96-hour registration trip permit for a vehicle not apportioned costs 20 dollars per single unit or 40 dollars per combination (W.S. 31-18-201(s)), sold at ports of entry. An unladen permit for an owner-operator leaving a lease is 20 dollars and valid 10 days.

Base jurisdiction, renewal, and audit in detail
The rules that decide whether Wyoming can be your base jurisdiction, what qualifies, and what happens at renewal and audit. Each one is sourced.
- Base jurisdiction rules: Summary
- An applicant must have an established place of business in Wyoming or prove Wyoming residency. Effective October 1, 2025, the established place of business is an owned or leased physical structure in Wyoming with a lease of at least 12 months, company signage and posted hours, staffed at least 20 hours per week by a permanent employee managing the trucking business; virtual and shared offices do not qualify.
- Base jurisdiction rules: Business premises
- Owned or leased structure, clear signage, posted hours, open for business.
- Base jurisdiction rules: Evidence
- Business: lease or property tax proof, photos of signage, utility bill in the business name, pay stubs and job description, business tax return with a Wyoming address. Residency: Wyoming driver license (the individual owner's or a principal owner's) plus at least two of a utility bill, a Wyoming-registered personal vehicle, a residence property tax bill, a lease, or a Wyoming-address income tax return.
- Qualifying vehicles: Summary
- A power unit used in two or more member jurisdictions that carries persons for hire or is designed for property, with two axles and over 26,000 pounds, three or more axles regardless of weight, or a combination over 26,000 pounds. Recreational vehicles, restricted-plate vehicles, SUVs, passenger vans and government vehicles are not apportionable; lighter power units and charter buses may register at the registrant's option.
- Renewal: Summary
- Renewals are staggered quarterly, with the period set when the account opens. Renewal packets are emailed six to eight weeks before expiration; the renewal must be received at least 30 days before the current registration expires, fees are billed afterward and must be paid in full before credentials issue, and same-day service is not available for renewals.
- Reciprocity: Summary
- Apportioned registration covers any type of operation except where intrastate authority is required: a Wyoming-registered vehicle may not run in intrastate commerce without intrastate authority from WYDOT (W.S. 31-18-201(m)). See the state intrastate authority page.
- Audit: Summary
- Keep distance records for the current and past three registration years. Failing to keep or produce records within 30 days brings an assessment of 20 percent of apportionable fees for a first offense, 50 percent for a second, and 100 percent for a third. Sums due on audit carry interest of 1.75 percent per month, plus 1 percent per month for deliberate evasion (W.S. 31-18-201(r)).
What the Wyoming share of the fee is built from
An IRP bill is the base jurisdiction's own registration fee for the vehicle, apportioned by mileage, plus the same for every other jurisdiction on the cab card. These are the Wyoming inputs to that calculation, each with its official source.
- Wyoming share
- The Wyoming portion is a county fee of 15 dollars plus 3 percent of factory price and special equipment, multiplied by 0.60 in the first year of service, stepping down to 0.15 from the sixth year, plus a state fee by gross weight (for example 907.50 dollars at 78,001 to 80,000 pounds). Trailers are not apportioned: Wyoming-based trailers pay a yearly county plate fee on value and age.
Who needs apportioned plates
A power unit that runs in two or more member jurisdictions and carries people for hire or is built for property qualifies when it is a heavy two-axle truck, has three or more axles, or runs in a heavy combination. Recreational, restricted-plate, and government vehicles are not apportionable, and lighter units may apportion by choice. Trailers are not apportioned in Wyoming.
The Wyoming base rules
You need an established place of business in Wyoming or proof of Wyoming residency. The business rule calls for an owned or leased physical office with a lease of a set minimum term, signage, posted hours, and a permanent employee on site for a set number of hours each week. Virtual and shared offices do not count. Residency proof starts with a Wyoming driver license plus other documents.
Opening an account
Send the IRP application and Schedule A/C with the checklist documents: EIN proof, good standing for an LLC or corporation, an active USDOT number with interstate authority and a current MCS-150, the annual certification forms, heavy vehicle use tax proof for the heaviest trucks, insurance, titles, and any leases. First-year fees use Wyoming's average distance chart, and credentials issue only after every document is in and the bill is paid.
Fees and the cab card
Each jurisdiction's full-year fee is multiplied by the fleet's share of distance there. Wyoming's own share combines a county fee based on factory price that steps down with the vehicle's age and a state fee by gross weight. Refunds are limited to fees paid by mistake, though fees can transfer to a replacement vehicle within the year.
The cab card lists every IRP jurisdiction under full reciprocity and must ride in the power unit. Check the VIN, weights, name, dates, USDOT number, and plate when it arrives.
Renewals, temporary tags, and audits
Renewals are staggered by quarter, packets arrive by email ahead of expiration, and the renewal must reach WYDOT a set time before the plates expire. Temporary authority covers a newly bought truck on an account in good standing. Keep distance records for the current and past registration years, because missing records bring an assessment that grows with each offense, and audit balances carry interest.
Reach the Wyoming IRP office
Account problems, supplement filings and credential replacements all route through the office that holds the account. Everything below is the agency's own published channel; where it publishes no phone line, the note says so rather than pointing at a permit vendor's number.

- Notes
- The phone line is the one printed on WYDOT's own IRP page ("For more information call (307)777-4829") and repeated in the IRP checklist, application and manual. It is the IRP unit, not a permit desk: 307-777-4827 is the IFTA Section, 307-777-4850 is Operating Authority, and the Highway Patrol port of entry and Overweight Loads Office numbers (307-777-4376) handle trip and oversize permits. Office hours are 8:00 a.m. to 4:30 p.m. Monday through Friday, and new applications are not processed after 3:00 p.m.
What pairs with IRP
The same interstate operation that needs apportioned plates almost always needs an IFTA license through Wyoming, and heavy power units owe the federal Form 2290 heavy vehicle use tax before plates renew. To compare how other states run IRP, see the national IRP registration table.
