John and Horace Dodge started the Dodge Brothers Motor Vehicle Company in 1914. They started with a sedan, but expanded into trucks by 1917. Dodge was sold to the Chrysler Corporation in 1928 where it remains today. Dodge trucks contain the standard 17-digit Vehicle Identification Number required for all vehicles manufactured since 1984. Each character has a specific meaning and can be used to identify an individual vehicle, just as DNA can identify and individual person. A example of a VIN for a 2005 Dodge Ram is 1D7EC12G05A12345.

The following are the specific codes: 1 – Manufactured in the US 2 – Manufactured in Canada 3 – Manufactured in Mexico 4 – Diamond Star Motors manufactured in the United States

Step 2

Find the second character. This should be the letter D for any Dodge vehicle. Other manufacturers will have other codes in this location. Find the third character. This should the be number 7 to indicate it is a truck. Other numbers and their meaning include: 4 – Multipurpose passenger 5 - Bus 6 – Incomplete

The tenth character indicates the year of manufacture. Any vehicle manufactured in 2005 should have a 5 in this location.
