These include 621,261,858 (prefixes which use 1-301-569-xxxx for local call to 301-569). I believe 621,261,858 had 1+7D (now 1+301+7D) instead of 301+7D dialing to long-distance points within Md. Arcola, Va. (Loudoun County) is 703-327. As of now, Herndon (Va.) has 7D local calls to there AND to DC, and 301-327 is in Baltimore city, so there is no 327 in DC or Md. suburbs (the 10D local calls across NPA boundaries will make 327 available in DC). Stafford, Va. is 703-659. I know of 301-659 in Baltimore city. 659 COULD occur in DC (I don't have prefix list with me as I write this). So when Md. and Va. suburbs are removed from area code 202, you will (as is the case with an area code split) be shrinking an existing area code. However, you are not creating a new area code. I believe a way to summarize these changes is that the new 10-digit local calling scheme affects those points within the DC calling area. (Note that I did not have the info about Pentagon <--> Prince William being extended-area local when I came up with that idea.) As far as I know, if you are in Md. and local to Va. (or vice versa), you are also local to DC. (Speaking of the Pentagon: it was written a while back in this Digest that pay phones in it are in the Arlington, Va. exchange; however, I don't know if they are in the Rosslyn-area exchanges or in the Crystal City & National Airport area exchanges.) By the way, time of day is set up as a local call throughout Maryland. Prior to these DC-area changes (i.e. now) you dial 844-1212 to get Baltimore time of day, unless you are in the DC calling area, in which case you dial 844-2525 to get Washington time of day.
