USPS has a zip code lookup feature on their web site and seems like
they would expect a lot of people using it....

Also be advised that too many hits from one place may result in
alarms going off. It may have changes since I thought about doing
this way back when, but they offered this site as a way for the
every day user to get a zip+4, not for a commercial app to do it on
the cheap as a way to avoid paying for the zip+4 database, which
back then at least they charged you for.

The USPS appears to have extensive APIs available - looks like it

I sent this message a while back, but I suspect it got lost in the
RunRev-LiveCode changeover.
At the USPS web site (http://zip4.usps.com/zip4/) it is possible by
entering the street address, the city and the state to obtain the
9 digit
zip code for that address.
This may be naive, but is it possible to do this from within
LiveCode by
script?
