Zip+4 Lookup and USPS Address Validation
Our society sends materials using a bulk mailing permit. Each addressee in such a mailing must have a zip+4 address code. Currently, we are looking these up manually as we enroll new members, a process that is cumbersome.
The USPS publishes an API which allows access to USPS zip+4 data and a means to clean addresses as well. We would like automated access to this data (i) to correct addresses submitted by new members either by mail or via online enrollment through PayPal.
There should be two means to start the process: (i) a button next to the zip code field; (ii) an additional method for the "approve button" when the application of a new member is accepted.
