What information should go into the Federal Commercial Vehicle Code (DCH) field used in the bar code?
As yet, the Federal government has not established codes for this purpose. Therefore, AAMVA recommends a solution that differs for a commercial license (CDL) and a non-commercial license. For a CDL, fill the Federal Commercial Vehicle Code field using the same data as in the Jurisdiction-Specific Vehicle Class (DCA) field. For a non-commercial license, fill the Federal Commercial Vehicle Code field with “NONE”.
