Use this as a lighter-weight fraud signal than check_carrier_identity: how many distinct business addresses and phone numbers a carrier reports across FMCSA's independent records of it (census, licensing and insurance, crash reports). Several different addresses on one carrier is a common re-registration tell. Billed whenever the USDOT number resolves.
