A painstakingly collected data set for country info validation. I got quite tired of independent lists that needed reformatting and that did not have all the necessary info per data set. This is the most comprehensive object json I am aware of. I am going to be writing PHP/JS code for loading and quick data extraction but essentially all you need to do is download the JSON file (CountryData_minify.json) and load it in your scripts and your ready to go.

This data set merges 8 different independent datasets to create a single master country json object that can be used for HTML/Code validation when dealing with country specific information.

    // Two files:
    CountryData_minify.json (233k)
    CountryData_pretty.json (531k)

I now use this object to auto-build Country <select> menus which then preformat and provide validation for all other input/select fields related to that country (IE: state lists, postal/zip code, phone numbers (country code and local number formats))

This object can be used to cross reference any country specific information for:

    // Object Data Includes:
    Alpha2 code
    Alpha3 code
    short name    // (ie: United States)
    long name     // (ie: United States of America)
    isoNumber code
    ioc code      // (olympic committee)
    currency  // see "NOTE 1"
        currency code []
        currency name [] 
        currency symbol [] 
    Languages
    Phone:
        country code    // (ie: +1 (US))
        mobile_begin_with prefix codes
        Phone format lengths    // (ie: XXXYYYZZZZ (10))
    Postal:  // see "NOTE 2" 
        Postal code formats
        Permitted non-postal characters
        Included postal validation regex
        Postal lengths    // see "NOTE 3"
        character sets    // (keyboard/input types: number or text (varchar))
    Country States & State Codes    // (ie: "Alaska" : "AK" )

Sample JS calls:

  //javascript:
  var obj = { dataset } ;
  console.log(obj.country["BEL"]) ;

The above format uses lookup by the 3 character country code (IE: USA) and returns all info about that country. But you can also do quick reverse lookups to get the the 3 character code if you only have country name or country 2 digit code:

//Javascript
var obj = { dataset } ;

// extract country info with only 2 digit code
var alpha3 = obj.country[obj.alpha2_to_alpha3["BE"]] ;  
console.log(obj.country[alpha3] ;

// extract country info with only country name
var alpha3 = obj.country[obj.name_to_alpha3["Belgium"]] ;  
console.log(obj.country[alpha3] ;

Please help keep this data accurate or make contributions to it to expand the datasets. Things that could be added are known zip/postal codes PER country STATE as well as local phone prefix numbers.

NOTE 1: Currencies: Some countries have multiple codes but only one name and symbol (ie: Colombia). Others have multiple codes/multiple names but only one symbol and yet others have multiple codes, names and symbols (ie: Namibia)

NOTE 2: Postal Codes: Not all countries have postal info avaialble. To create consistent data, I analyzed those countries and came up with a default solution Description="No Data", charSet="varchar", postalLength=["7"], ValidationRegex="[a-zA-Z0-9]" for uniformity. You may find my chosen defaults do not suit you. Test for obj.country[code].postal.Description == 'No Data' to create your own defaults...if any.

NOTE 3: Postal Code Lengths: Length variations account for spaces and dashes. US ["5", "10"]. "10" = "12345-1234" or "12345 1234"
