DESCRIPTION

*** THIS IS ALPHA SOFTWARE ***

This module implements the Address Standardization web service from the US Postal Service. It is a subclass of Business::US::USPS::WebTools.

lookup_city_state( KEY, VALUE, ... )

The "verify_address" method takes the following keys, which come directly from the USPS web service interface:

        FirmName        The name of the company
        Address1        The suite or apartment
        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.
