What this is
FMCSA requires every electronic logging device to be registered by its maker, and it publishes the list — along with the devices whose registration has been revoked, either by the agency or by the maker withdrawing it. The identifier above is the short code the device shows on its own compliance screen. This page is a copy of what that public list says about it, kept searchable because the list itself is free to read and almost impossible to notice.
