For much the same as the reasons given here:
http://www.census.gov/geo/www/tiger/tigermap.html#ZIP

"The fact that ZIP Codes aren't required to be polygons makes them
difficult to map. They are networks of streets served by mail carriers
or just individual post offices and are a tool for mail delivery. They
also change periodically as required to meet Post Office operational
needs. Various companies have created maps by interpolating boundaries
between occurrences of ZIP Codes on the ground. However, this does not
guarantee that the U.S. Postal Service delivery routes will follow
this interpretation."
