The following is a summary of the paperwork that must be filed with the UIIA in order to participate in the Uniform Intermodal Interchange and Facilities Access Agreement.

All Motor Carriers must also provide their USDOT Number and Federal Tax ID on Form 2. In addition, a Motor Carrier Operating Authority Number (MC Number) will be required if applicable to your business operations. New UIIA applications will not be approved until the Motor Carrier’s USDOT and MC Number (if applicable) are showing active on the Department of Transportation’s SAFER website at

If you are paying your Annual Administrative Service Fee by VISA, MasterCard, or American Express, you will need to complete the payment information portion of the Annual Fee Schedule. If you are paying your Annual Administrative Service Fee by check, simply fax a copy of the check to our office along with your paperwork. (We must receive the original check within seven to 10 days.)

Existing UIIA Motor Carriers — If mailing a check to remit payment of a renewal, please make sure to send the check to UIIA, P.O. Box 79445, Baltimore, MD 21279-0445.

Instructions to your insurance agent — You will need to complete Form 5C (Equipment Provider Checklist) of the insurance instructions by checking off the Equipment Providers that your company does business with.  After completing Form 5C, please forward the entire insurance instruction packet to your insurance agent for completion.
