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 countries
Or you can install via Bundler if you are using Rails:
bundle add countries
Simply 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
Please 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

Please note that latitude_dec

fields have been switched decimal coordinates.

.collect_countries_with
allows to collect various countries' information using any valid method and query value:
> ISO3166::Country.collect_countries_with("VR",:subdivisions,:common_name)
=> ["Italy", "Monaco"]
> ISO3166::Country.collect_countries_with("Caribbean",:subregion,:languages_spoken).flatten.uniq
=> ["en", "fr", "es", "ht", "nl"]
> ISO3166::Country.collect_countries_with("Oceania",:region,:international_prefix).uniq

> ISO3166::Country.collect_countries_with("Antarctica",:continent,:emoji_flag)
=> ["🇦🇶", "🇬🇸", "🇧🇻", "🇹🇫", "ðŸ‡ðŸ‡²"]
> ISO3166::Country.collect_countries_with("🇸🇨",:emoji_flag,:common_name)
=> ["Seychelles"]
.collect_likely_countries_by_subdivision_name
allows to lookup all countries having the given state code or state name (in any translation)
ISO3166::Country.collect_likely_countries_by_subdivision_name("San José",:common_name)
=> ["Costa Rica", "Uruguay"]
ISO3166::Country.from_alpha3_to_alpha2('USA') # => "US"
ISO3166::Country.from_alpha2_to_alpha3('US') # => "USA"
ISO3166::Country.from_alpha2_to_alpha3('--') # => nil
To enable currencies extension please add the following to countries initializer.
ISO3166.configuration.enable_currency_extension!
Please note that it requires you to add "money" dependency to your gemfile.
gem "money", "~> 6.9"
Countries now uses the Money gem. What this means is you now get back a Money::Currency
object that gives you access to all the currency information.
c = ISO3166::Country['us']
c.currency.iso_code # => 'USD'
c.currency.name # => 'United States Dollar'
c.currency.symbol # => '$'
A template for formatting addresses is available through the address_format method. These templates are compatible with the Liquid template system.
c.address_format # => "{{recipient}}\n{{street}}\n{{city}} {{region}} {{postalcode}}\n{{country}}"
As of 2.0 you can selectively load locales to reduce memory usage in production.
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]
end
or something a bit more simple
ISO3166.configure do |config|
config.locales = [:en, :de, :fr, :es]
end
If 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: Country
Adds 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
end
