California License Plates:
Occupational License Plates

as observed by Roger M. Wilcox
Last updated 10-Sept-2025



These are license plates for vehicles that either haven't been bought yet, or are destined for the junk heap, but which still need to be transported on the road.

The license number consists of a three-letter code for the type of plate (manufacturer, distributor, dealer, dismantler, etc.), a full-sized number in all digits, and a small two-to-four-character code consisting of 1-3 digits followed by a letter. The full-sized number is assigned to the occupational entity (the dealer, the manufacturer, etc.), not to the vehicle, and does not vary over the occupational entity's lifetime. All of these characters — the three-letter entity-type code, the full-sized digits, and the small 2-4 character code — are considered part of the license plate number.

During the blue license plate era, the three-letter entity code was replaced with the full word describing the entity ("DEALER", "DISTRIBUTOR", etc.). This word appeared in small embossed type at the bottom-left of the plate, and the 2-4 character code was laid out horizontally at the bottom-right of the plate. The use of a vertically-stacked 3-letter entity-type code was resumed in the California Sunset license plate era.


Manufacturer plates

These plates are used by auto and truck manufacturers. They have the letters "MFG" on the left, in small type stacked on top of one another. There is also a two- or three-character code, with both/all characters stacked vertically. On old plates (black plate era and older), this code was on the far left, to the left of the MFG. On modern plates, this code is on the far right. Both the MFG and the three-character code are considered part of the license plate number.

    These plates are used by auto and truck dealers. They have the letters "DLR" on the left, in small type stacked on top of one another.

On modern plates, this code is on the far right. Both the DLR and the three-character code are considered part of the license plate number.
