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 (countries), ISO3166-2 (states/subdivisions), ISO4217 (currency) and E.164 (phone numbers).
The data used in this gem is also available as git submodules in YAML and JSON files.
gem install countriesOr you can install via Bundler if you are using Rails:
bundle add countriesSimply load a new country object using Country.new(alpha2) or the shortcut Country[alpha2]. An example works best.
c = ISO3166::Country.new('US')Get all country codes (alpha2).
ISO3166::Country.codes
# ["TJ", "JM", "HT",...]Some apps might not want to constantly call ISO3166::Country this gem has a
helper that can provide a Country class
# With global Country Helper
c = Country['US']This will conflict with any existing Country constant
To Use
gem 'countries', require: 'countries/global'Release 4.2.0 introduced changes to name attributes and finders and deprecated several methods to resolve some existing confusion regardign official ISO country names vs. the "common names" that are commonly used.
The 5.0 release removed these deprecated methods and also removed support for Ruby 2.5 and 2.6
Plase see UPGRADE.md for more information
You can lookup a country or an array of countries using any of the data attributes via the find_country_by_attribute dynamic methods:
c = ISO3166::Country.find_country_by_iso_short_name('italy')
c = ISO3166::Country.find_country_by_any_name('united states')
h = ISO3166::Country.find_all_by(:translated_names, 'França')
list = ISO3166::Country.find_all_countries_by_region('Americas')
c = ISO3166::Country.find_country_by_alpha2("FR")For a list of available attributes please see ISO3166::DEFAULT_COUNTRY_HASH.
Note: searches are case insensitive and ignore accents.
Please note that find_by_name, find_by_names, find_*_by_name and find_*_by_names methods were removed in 5.0. See UPGRADE.md for more information

By default we load I18n.available_locales if I18n is present, otherwise only [:en]. This means almost any Rails environment will only bring in its supported translations.
You can add all the locales like this.
ISO3166.configure do |config|
config.locales = [:af, :am, :ar, :as, :az, :be, :bg, :bn, :br, :bs, :ca, :cs, :cy, :da, :de, :dz, :el, :en, :eo, :es, :et, :eu, :fa, :fi, :fo, :fr, :ga, :gl, :gu, :he, :hi, :hr, :hu, :hy, :ia, :id, :is, :it, :ja, :ka, :kk, :km, :kn, :ko, :ku, :lt, :lv, :mi, :mk, :ml, :mn, :mr, :ms, :mt, :nb, :ne, :nl, :nn, :oc, :or, :pa, :pl, :ps, :pt, :"pt-BR", :ro, :ru, :rw, :si, :sk, :sl, :so, :sq, :sr, :sv, :sw, :ta, :te, :th, :ti, :tk, :tl, :tr, :tt, :ug, :uk, :ve, :vi, :wa, :wo, :xh, :"zh-cn", :"zh-tw", :zu]
endor something a bit more simple
ISO3166.configure do |config|
config.locales = [:en, :de, :fr, :es]
endIf you change the value of ISO3166.configuration.locales after initialization, you should call ISO3166::Data.reset to reset the data cache, or you may end up with inconsistently loaded locales.
As of 5.1.1, subdivision translations also respect this and will only load the selected locales.
As of 2.0 countries supports loading custom countries / overriding data in its data set, though if you choose to do this please contribute back to the upstream repo!
Any country registered this way will have its data available for searching etc... If you are overriding an existing country, for cultural reasons, our code uses a simple merge, not a deep merge so you will need to bring in all data you wish to be available. Bringing in an existing country will also remove it from the internal management of translations, all registered countries will remain in memory.
ISO3166::Data.register(
alpha2: 'LOL',
iso_short_name: 'Happy Country',
translations: {
'en' => 'Happy Country',
'de' => 'glückliches Land'
}
)
ISO3166::Country.new('LOL').iso_short_name == 'Happy Country'Mongoid support has been added. It is required automatically if Mongoid is defined in your project.
Use native country fields in your model:
field :country, type: CountryAdds native support for searching/saving by a country object or alpha2 code.
Searching:
# By alpha2
spanish_things = Things.where(country: 'ES')
spanish_things.first.country.iso_short_name # => "Spain"
# By object
spanish_things = Things.where(country: Country.find_by_iso_short_name('Spain')[1])
spanish_things.first.country.iso_short_name # => "Spain"Saving:
# By alpha2
spanish_things = Thing.new(country: 'ES')
spanish_things.save!
spanish_things.country.iso_short_name # => "Spain"
# By object
spanish_things = Thing.new(country: Country.find_by_iso_short_name('Spain')[1])
spanish_things.save!
spanish_things.country.iso_short_name # => "Spain"Note that the database stores only the alpha2 code and rebuilds the object when queried. To return the country name by default you can override the reader method in your model:
def country
super.iso_short_name
