Presently in area 301: Laurel 725,776,490,etc. is local to Washington (and the Pentagon in Va.) and the Md. suburbs in between, but not to other Virginia points. Exceptions for Laurel: 792 (etc.?) available for Baltimore metro service, and 621 & 953 (etc.?) for Washington metro service. (621 is called "Bowie-Glenn Dale service" and 953 is called "Berwyn service".) The next exchange up the U.S.1/I-95 corridor from Laurel going toward Baltimore is 799 Waterloo, which is part of the Baltimore metro exchanges. From what I have read (only here in Telecom), I assume that the 301/410 line will pass between Laurel and Waterloo.
