New addresses for paying Coast Guard vessel inspection user fees by check

The addresses for submitting payments by check to the Coast Guard, including for vessel inspection user fees, have changed. Payments sent to the old addresses will not be forwarded to the Coast Guard. Payments received after the due date will result in late fees and penalties.

US Coast Guard Vessel Inspection
P.O. Box 979118
St. Louis, MO 63197-9000

If using a delivery service that requires a street address, use the following address:
