*** THIS IS ALPHA SOFTWARE ***
This module implements the Zip Code Lookup web service from the US Postal Service. It is a subclass of Business::US::USPS::WebTools.
The lookup_zipcode method takes the following keys, which come directly from the USPS web service interface:
Address2 The street address
City The name of the city
State The two letter state abbreviation
Zip5 The 5 digit zip code
Zip4 The 4 digit extension to the zip code
It returns an anonymous hash with the same keys, but the values are the USPS's canonicalized address. If there is an error, the hash values will be the empty string, and the error flag is set. Check is with is_error:
$verifier->is_error;
See the is_error documentation in Business::US::USPS::WebTools for more details on error information.


The WebTools API is documented on the US Postal Service's website:

This source is part of a SourceForge project which always has the latest sources in CVS, as well as all of the previous releases.

If, for some reason, I disappear from the world, one of the other members of the project can shepherd this module appropriately.
