ZipCodes

Simple gem to get city, state, and time zone for a given zip code. It has a yaml database bundled with it, so you need several mb of memory for the whole hash.

The gem currently supports only US zip codes. The data origin is https://download.geonames.org/export/zip/

The main maintainer is https://github.com/brodyhoskins

Add this line to your application's Gemfile:

gem 'zip-codes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install zip-codes

ZipCodes.identify('30301')
# => {:state_code=>"GA", :state_name=>"Georgia", :city=>"Atlanta", :time_zone=>"America/New_York"}
# First run will take a while, as the yaml has to be loaded

If you are using Rails, you can load the hash on app startup for production and staging.

# config/initializers/load_zip_codes.rb
ZipCodes.load unless Rails.env.development?
