I checked out some prefixes in the Columbia & Laurel areas:

596 Columbia (Laurel local service) stays in 301
792 Laurel (Baltimore-metro local service) goes into 410
776 Laurel (the "default" local service, which includes DC but not Va.)
     stays in 301
992 Columbia (the "default" local service, which includes Baltimore city
     but not all of Baltimore metro) goes into 410
