I'm working under the assumption it is no longer maintained, hence we have our own fork.

Aside from a few minor performance pieces (I see @ankane has made some improvements in his fork), it seems the the majority of PR's and forks are primarily dealing with updates to the underlying database.

This is a useful project. If the author is amenable (paging @jgv), would he consider transferring the project to the (ideally) the owners of one of the existing forks. I'm happy to volunteer if no-one else is interested.

It would be good to verify support for Ruby 2.x, dust off some of the cobwebs and perhaps think about a better process for submitting updates/addition to the underlying data.

@ckorhonen I tend to agree, transitioning ownership would be nice.

Additionally, I don't know where the actual zip code data is coming from. From my own person research it looks like some of it had been scraped from census data, but I also found an old issue that points to http://federalgovernmentzipcodes.us/ being used for data.

Worst case scenario we just create a new gem with more official data sources and a more modern ruby support.

This project is also ver similar in nature and more active: https://github.com/monterail/zip-codes
