I don't know of any N0X/N1X prefixes currently in use in Maryland,
but an earlier posting by me mentioned new 202-915 (Washington, DC).
The long-distance dialing instructions for Md., DC, and Va. were changed
late last year (local calls are still made with just the 7 digit number,
with exceptions I noted near Severn, Md.):
OLD--in DC and all but outermost Md. and Va. suburbs, use areacode + number,
even if within Md. or 703 area in Va.; elsewhere in Md. and Va. use 1+areacode
+number.
NEW--in Md., DC, and 703 area in Va., use 1+areacode+number. (In DC area, the 1+
is new requirement; elsewhere in Md. and 703, use of areacode within one's own
area is new requirement.)
