Cummins Engine Serial Number Locations

The easiest way to find your Cummins engine serial number is by consulting your owner’s manual. If you don’t have the original manual, have no fear. Cummins makes it relatively easy for you to find the data you require.

The good news is you can identify your Cummins engine serial number location and other vital information such as RPM rating, horsepower and a Critical Parts List (Cummins CPL lookup) by checking the data plate. However, finding the Cummins engine data plate can be difficult because they are frequently located in different positions depending on the model and year.
