Cummins has been incredible diesel engines for years now, and all of them have an identification number. Depending on the engine, it’ll be in a different place.
Cummins can trace its history back to 1919, when Clessie Cummins and William G. Irwin founded the Cummins diesel engine brand. Since then, it has churned out millions of engines, with each one being individually numbered. Knowing this number can come in handy for a variety of reasons. For example, it can help you find the right part for your engine more easily, or file a warranty claim if something goes wrong.
This ID number on Cummins engines is often called the EIN (Engine Identification Number) or ESN (Engine Serial Number). Since Cummins prefers the latter term, from here on out, we’ll refer to it as the ESN. In most cases, the number consists of eight digits. To find the ESN of any particular Cummins engine, you’ll need to find its dataplate.
