You have to be a little careful because Zip codes do not follow MSA
boundaries and do not even follow municipal, county or state
boundaries...always. If you look at a map of Northern Virginia
you will find that there is at least one Zip code in North
Arlington that also includes part of Fairfax. There is supposed
to be some areas out West where Zip codes don't follow state
lines. Zip codes are based on mail delivery routes, not political
Just to complicate things, I live in Fairfax county, but the post
office insists that my mailing address is Alexandria which is (as
you probably know from your address) an independent city.
Makes our work interesting.
