    • If the payment receipt is printed from the payment screen, please continue with the permit to finalize.

Please see ENTERING EPART PAYMENTS USING PAYZANG document for assistance in processing payments.

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.
