California Air Resources Board

The In-Use Off-Road Diesel-Fueled Fleets Regulation (Off-Road Regulation) requires that all vehicles subject to the Off-Road Regulation be labeled with a unique equipment identification number (EIN).  Note that as of January 1, 2013, off-road vehicles subject to the Off-Road Regulation must have two EIN labels; one on each side.  As of June 30, 2017, equipment subject to the Large Spark-Ignition (LSI) Engine Fleet Requirements Regulation fleet average emission limit requirements must have one EIN label.

Fleet owners have a choice of how they want to label their vehicles/equipment. For example, fleets may label their vehicles/equipment with vinyl stickers or aluminum placards (either may be purchased, or created in-house), or by painting the EIN on the vehicle/equipment. The most common method is to purchase vinyl stickers. It is the fleet owner’s responsibility to comply with the Off-Road and LSI Fleet Regulations, including ensuring that the labels that are attached to their vehicles/equipment meet the label specifications, which are described in this off-road FAQ document  and in the LSI Fleet Regulation.

ARB does not supply the EIN labels themselves. As a courtesy, ARB has assembled the following list of contact information for vendors (graphics businesses) who supply EIN labels that may comply with the requirements of the Off-Road and LSI Fleet Regulations. ARB has also assembled a list of contact information for label maker vendors who  supply label makers that can fabricate labels which may comply with the requirements of the Off-Road and LSI Fleet Regulations. Fleet owners need not use a vendor from this list in order to comply with the Off-Road or LSI Fleet Regulations.

Publication of this list does not signify that the contents reflect the views and policies of ARB. Mention of vendors, trade names or commercial products does not constitute endorsement or recommendation for use by the Air Resources Board. All interested vendors are granted equal opportunity.

Vendors: To add your company to the list below, you will need to provide an example of a decal and/or placard meeting the label specifications. Please submit an example with the specifications to doors@arb.ca.gov.
