I'm looking for a web page that will give me a zip code from a
latitude and longitude. Would be better if it was a wap page. I'd like
to be able to find out what zip code I am in from my mobile phone. It
has GPS. Is there a better group to ask this question in?
The US Census Bureau has this to say about the problem:
The Census Bureau does not have maps or digital files showing
the boundaries of U.S. Postal Service ZIP Codes. 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.
