ZIP Codes Page Shut Down by the Post Office

The US Post Office sent us a special sort of holiday greetings -- apparently their policy has changed and non-profit institutions are no longer allowed to link to their ZIP Code database for the benefit of regular people sending regular mail -- the service is now only available for companies using special postal services. As a consequence the popular ZIP Codes, Etc. page will have to have its ZIP Codes portion disabled for the foreseeable future. Apparently they would rather have people calling them on the phone asking them for ZIP Codes than simply checking online... If you would like to complain about this change in policy, you can send them a (polite, please!) message via their feedback form.
