What is a Cummins Engine Serial Number?
A Cummins engine serial number (ESN) is a unique identifier that is assigned to every Cummins engine at the time of manufacture. It is usually stamped or engraved on a metal tag or plate that is attached to the engine block or cover. The ESN can also be found on the owner's manual, warranty card, or invoice of your engine purchase.
What information does it contain?
The ESN contains several segments that provide different information about your engine, such as:
The first segment indicates the engine model and series, such as ISX, ISB, QSK, etc.
The second segment indicates the critical parts list (CPL) number, which is a code that specifies the configuration and components of your engine.
The third segment indicates the horsepower and RPM rating of your engine.
The fourth segment indicates the emission statement or certification of your engine, if applicable.
The fifth segment indicates the serial number sequence, which is a unique number that distinguishes your engine from others of the same model and CPL.
Why is it important to know?
Knowing your ESN can help you in many ways, such as:
It can help you find the right parts and service for your engine.
It can help you verify the authenticity and history of your engine.
It can help you troubleshoot and diagnose any issues or problems with your engine.
It can help you register and claim warranty for your engine.
How to Find Your Cummins Engine Serial Number?
There are two main ways to find your ESN:
Locate the dataplate on your engine
The dataplate is a metal tag or plate that is attached to your engine block or cover. It contains the ESN and other information about your engine. The location of the dataplate may vary depending on the engine model and series. Here are some common locations where you can find the dataplate on different Cummins engines:
Engine Model/SeriesDataplate Location
4BT 3.9 /6BT 5.9The long narrow metal tag that is attached to the front cover/gear housing. If you have lost the tag, look on the left side of the block, when looking from the front of the engine, above the oil cooler housing.
6CTAThe long narrow metal tag that is attached to the front cover/gear housing. If you have lost the tag, look on the left side of the block, when looking from the front of the engine, above the oil cooler housing.
ISBThe datap late is located on the driver's side of the block, just below the head.
ISCThe dataplate is located on the driver's side of the block, just below the head.
ISLThe dataplate is located on the driver's side of the block, just below the head.
ISXThe dataplate is located on the driver's side of the block, just below the head.
QSBThe dataplate is located on the driver's side of the block, just below the head.
QSCThe dataplate is located on the driver's side of the block, just below the head.
QSLThe dataplate is located on the driver's side of the block, just below the head.
QSXThe dataplate is located on the driver's side of the block, just below the head.
QSKThe dataplate is located on the top of the rocker cover or valve cover.
If you have trouble finding the dataplate on your engine, you can refer to this [guide] from Cummins for more details and illustrations.

How to Decode Your Cummins Engine Serial Number?
Once you have found your ESN, you can decode it to learn more about your engine. The ESN consists of several segments that are separated by dashes or spaces. Each segment has a specific format and meaning that can be explained as follows:
Understand the format and meaning of each segment
The first segment of the ESN indicates the engine model and series. It consists of two or three letters that represent the abbreviation of the engine name. For example, ISX stands for Interact System X, QSK stands for Quantum System K, etc. The engine model and series determine the basic design and features of your engine.
The second segment of the ESN indicates the critical parts list (CPL) number. It consists of four digits that represent a code that specifies the configuration and components of your engine. The CPL number determines the fuel system, injectors, turbochargers, pistons, camshafts, valves, and other parts that are used in your engine. The CPL number also determines the compatibility and interchangeability of parts among different engines.
The third segment of the ESN indicates the horsepower and RPM rating of your engine. It consists of four digits that represent two numbers separated by a slash. The first number indicates the horsepower rating of your engine at a certain RPM level. The second number indicates the RPM level at which the horsepower rating is measured. For example, 400/1800 means that your engine has a horsepower rating of 400 at 1800 RPM. The horsepower and RPM rating determine the performance and efficiency of your engine.
The fourth segment of the ESN indicates the emission statement or certification of your engine, if applicable. It consists of one or two letters that represent the abbreviation of the emission standard or regulation that your engine complies with. For example, E stands for EPA (Environmental Protection Agency), C stands for CARB (California Air Resources Board), U stands for EU (European Union), etc. The emission statement or certification determines the level of emissions and pollution that your engine produces.
The fifth segment of the ESN indicates the serial number sequence, which is a unique number that distinguishes your engine from others of the same model and CPL. It consists of six digits that are assigned in ascending order as the engines are manufactured. The serial number sequence determines the identity and history of your engine.
