As of the 1960 issue, there was a distinction between New Car Dealer plates and Used Car Dealer plates.

Regular issue dealer plates used a DAA-00 numbering format, followed by the vehicle number in smaller digits.

"Dealer Courtesy" plates use a DAA 0 format (no dash) followed by the vehicle number.
