As of June 26, 2004, the Crystal City area of Arlington County in Northern Virginia underwent a number of changes. Many buildings' addresses were changed on this date, and several major roads were turned into two-way streets (Crystal Drive, 20th St., 18th St., and 15th St.). Unfortunately, many people use the old building names, yet the old markings with those names are now essentially gone. That means it's not unusual for someone to send you an address that's completely unfindable when you get there.
In addition, the road "Jefferson Davis Highway" has been renamed to "Richmond Highway".
So here are the old building names, old addresses, and new addresses, so you can find the buildings in Crystal City:

All of these addresses are officially part of Arlington, VA, so that is how you send mail to them. But the locals all refer to this area as "Crystal City" (the name of the development). Note: There is no "Crystal Square 1".
Note that the "Taylor Building" (used by the Army) has the official address 2530 Crystal Drive, Arlington, VA 22202. Jefferson Plaza I is located at 1411 and 1421 Richmond Highway (Jefferson Davis Highway) and 1480 Crystal Drive (RPC# 34-024-339, -340, and -341).
This Arlington map of Crystal City lets you find buildings by name and their new address, in particular select "View buildings by name" so you can find the new address of specific named buildings (though not the old addresses). This Crystal City site plan also shows you where the buildings are (with their new addresses).
