ATTENTION:
Effective 06/01/2020, MCS will begin taking walk in customers wishing to obtain permits as well as IRP and IFTA registrations. In order to meet the social distancing requirements, we will limit 2 customers in the office at a time. You may schedule an appointment to work with a License and Permit Tech by calling 406-444-6130. For time and efficiency MCS continues to encourage the use of our online License and Permit system known as ePART. See our Online Carriers page.

Diesel Fuel Users: Please be advised that the National and State Covid-19 Emergency Declaration does not include the ability to use non-taxed diesel fuel (dyed diesel) in motor vehicles traveling on public roads and highways. Using dyed diesel on Montana roadways could be result in a penalty not to exceed $1,000.00 for a first offense and $5,000.00 for a second offense.

USDOT Number updates: needed for Intrastate and Interstate carriers, this is a free service that is done by FMCSA and MCS/MDT. You will not receive calls from either entity requesting money to update this for you. If you receive a call from someone offering to do this for you for compensation, this is a scammer. To update your information, please see our FMCSA Page

A reminder to check your route for your Permits

When you begin issuing your own permits, it is important to remember your responsibility to check construction reports and load-speed restrictions to verify that the route you plan to take does not have unanticipated restrictions.

Payment Types accepted!

Electronic Checks; Visa, MasterCard, American Express, and Discover are accepted as Online payments types.

  • Electronic Checks have a $1.00 transaction fee added onto the price of the transaction.
  • The credit card fee of 2.45% + $.25 is being passed onto the carrier along with the price of the permit / credential. This will be noticed at the time of processing the payment.
  • The receipt will print out with your permit after payment has been completed and show the additional fees.
    • If the payment receipt is printed from the payment screen, please continue with the permit to finalize.

Draft Permit

The purpose behind a draft permit is to allow the customer to see if they can utilize a MT permit before paying for it. This would be beneficial such as when bidding a job to see how much a permit would cost before proceeding. (Please note the cost listed).

To get to a draft permit, the user will work up the permit until the Billing page. At the bottom on of the screen, instead of clicking Proceed to finalize the permit, the user would click the Draft Permit button.

This will bring up a copy of the permit (permit number is VOIDVOID). No amount is shown on the draft permit.

Is your federal information up-to-date?

To avoid unnecessary delays with MCS, please make sure that your information on the FMCSA Motor Carrier Unified Registration System is current. MCS does reference this information when a new account is set-up; and/or periodically as needed. Discrepancies between information provided to MCS and what shows up in the federal system, will slow down MCS processes.

If your business has changed its Company Name, USDOT number, TIN (Tax Identification number), and/or mailing or physical address, please make sure to update your forms on the FMCSA site. After this has been completed, please notify MCS at 406-444-6130 so that MCS can keep your account information updated on our MCS systems.
