PostalCodes

A gem to provide details related to postal code(country, state, locality, calling_code, country_code).

Currently it is having data only for India and USA.I will be updating for more countries as well

Add this line to your application's Gemfile:

gem 'postal_codes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install postal_codes

To Find information of postal code(Numeric only) :

PostalCodes.find_all(110094) OR PostalCodes.find_all("110094")

To Find information of postal code(Alphanumeric) :

PostalCodes.find_all("110094")	

It will return the array of Hash:

[{"country"=>{"name"=>"India", "calling_code"=>"+91", "alpha_2_code"=>"IN", "alpha_3_code"=>"IND", "numeric_code"=>"356"}, "state"=>"DELHI", "locality"=>"Dayalpur,Khazuri Khas,Sabhapur,Gokal Puri,Johripur"}]

locality contains the comma separated list of localities which comes under given postal_code.

In rare case if a postal code present in more than one country then it will display result as follows :

[{"country"=>{"name"=>"India", "calling_code"=>"+91", "alpha_2_code"=>"IN", "alpha_3_code"=>"IND", "numeric_code"=>"356"},"state"=>"DELHI", "locality"=>"New Delhi"}, {"country"=>{"name"=>"USA","calling_code"=>"+1","alpha_2_code"=>"US", "alpha_3_code"=>"USA", "numeric_code"=>"840"},"state"=>"Alabama", "locality"=>"Moody"}]

First Load will take time to load. If using Rails, you can load the hash on app startup for production and staging.

# config/initializers/postal_codes_load.rb
