The images below show some of the more common locations for the Serial Number on the frame of 1939 to 1947 Dodge and Plymouth Trucks, though the number may be several inches to either side, above, or below the locations shown. Different models, and sizes of trucks in the Job Rated era got the frame number stamped in different locations, so there are images below that show several different examples of frame number locations. Detroit and California built trucks also sometimes got the numbers stamped in different locations on the same model truck, just to make things more interesting. Most of the trucks that have been checked have their numbers in the locations shown below, but other locations may have been used throughout the years.

Dodge may have used a small child with a tack hammer to strike the number die, as the stamps are often shallow, and may be hard to find. Here are a few tips to make finding the number easier.

1. Clean the area down to bare metal, a wire wheel in a drill works well for this.

2. Clean a larger area then shown in the images, the number may be in a slightly different spot.

3. Getting the area wet (water works fine for this, or some light oil) can help make some numbers easier to read.

4. If the area is rusty or the number is hard to make out, take close up digital images of the number, and enlarge them on the computer. This trick often helps make out a hard to read number.
