All sorts of useful information about every country packaged as pretty little country objects. It includes data from ISO 3166 (countries and states/subdivisions ), ISO 4217 (currency), and E.164 (phone numbers). As a bonus it even adds a country_select helper to rails projects.

Countries is a collection of all sorts of useful information for every country in the ISO 3166 standard. It contains info for the following standards ISO3166-1 and E.164. Next release will contain ISO3166-2 and ISO4217. I will add any country based data I can get access to. I hope this to be a repository for all country based information.


The data in this gem is collected from many different sources including CommonDataHub and represents a best effort to be accurate and up to date. It is used at your own risk.


Countries is hosted on GemCutter, so simply run the following:

gem sources -a
sudo gem install countries

Use It!

Simply load a new country object using 3166 alph2 code) or the shortcut Country[iso 3166 alph2 code]. An example works best.

c ='US')
c = Country['US']

Then you have all sorts of methods on the Country object to give you info about the country.

c.number # ISO3166 numeric country code
c.alpha2 # ISO3166 alpha2 country code
c.alpha3 # ISO3166 alpha2 country code # ISO3166 name
c.names # ISO3166 alternate names
c.latitude # uuuh the latitude
c.longitude # obvious?
c.region # UN Region
c.subregion # UN SubRegion
c.country_code # E.164 Country Code
c.national_destination_code_lengths # E.164 length of national destination code
c.national_number_lengths # E.164 length of the national number
c.international_prefix # E.164 code for dialing international from country
c.national_prefix # E164 code for dialing within the country
