The motor carrier is responsible for checking that their device is registered. This includes checking both the registration and revocation list periodically. The list of registered and revoked ELDs can be found on the following link: https://3pdp.fmcsa.dot.gov/ELD/ELDList.aspx.
In the event that an ELD is removed from the registration list, FMCSA will make efforts to notify the public and affected users. Motor carriers and drivers are encouraged to sign-up for ELD Updates to receive notifications on when an ELD has been listed on the Revocation List.
