There was a Moderator's Note saying:

They were set up by different organizations, but the zip-area
directory I pointed out earlier is a correlation of these.  I must
caution, however, that it is subject to "noise" along an area code
boundary; i.e., a zipcode could cross an area code boundary (the
zip-area directory only lists the area code for some "majority" of
each zip code).
