Manufacturer Certificate of Origin

Synonym: MSO.
A Manufacturer's Certificate of Origin (MCO), also known as a Manufacturer’s Statement of Origin (MSO), is a document certifying a manufacturer built a vehicle. For new vehicles, MCOs are required for the export or import in and out of the U.S. MVAs treat the MCO as a proof of ownership document, prior to the issuance of a title.
The elements on a MCO describe Vehicle and identify the Auto Dealer where the vehicle was shipped. The requirements for the fields needed on an MCO come from State regulations.
MCO Elements
The data on a MCO can vary by manufacturer, vehicle type and when the MCO was issued.
While most major manufacturers now use similar forms for ground vehicles (shown on the left), there are variations in how some of the fields are populated. On older forms there is more variation between the manufacturers.
Vessels are described by different elements and use a different MCO Boat form. The requirements for Boat MCOs come from the USCG.
