The United States Postal Service (USPS) has on its web site an HTML form at C<www.usps.com/zip4/> for standardizing an address. Given a firm, urbanization, street address, city, state, and zip, it will put the address into standard form (provided the address is in their database) and display a page with the resulting address.
This Ruby module provides a programmatic interface to this service, so you can write a program to process your entire personal address book without having to manually type them all in to the form.
Because the USPS could change or remove this functionality at any time, be prepared for the possibility that this code may fail to function. In fact, as of this version, there is no error checking in place, so if they do change things, this code will most likely fail in a noisy way. If you discover that the service has changed, please email the author your findings.
BE SURE TO READ AND FOLLOW THE UNITED STATES POSTAL SERVICE TERMS OF USE PAGE (AT C<www.usps.com/homearea/docs/termsofuse.htm> AT THE TIME THIS TEXT WAS WRITTEN). IN PARTICULAR, NOTE THAT THEY DO NOT PERMIT THE USE OF THEIR WEB SITE’S FUNCTIONALITY FOR COMMERCIAL PURPOSES. DO NOT USE THIS CODE IN A WAY THAT VIOLATES THE TERMS OF USE.
