All vehicles subject to the in-use off-road diesel-fueled fleets regulation should be labeled with Equipment Identification Numbers (EINs) by mid-September 2009. All EINs consist of six characters - two upper case letters, one number, one upper case letter, and then two numbers (for example, "RH4M79"). The letters, I and O, and the numbers 1 and 0, are not included in EINs.

If you suspect a vehicle you observe has a fraudulent EIN, you can look up further information on the vehicle including vehicle type, and vehicle manufacturer. Enter the EIN in the box provided. Be sure to use uppercase letters
