Get Country name from Country code in JavaScript

# Get Country name from Country code using JavaScript

Use the Intl.DisplayNames() constructor to get a country name from a country code.

The of() method on the returned object takes a code as a parameter and returns a string based on the provided locale.

Copied!
const regionNames = new Intl.DisplayNames(
  ['en'], {type: 'region'}
);

console.log(regionNames.of('US')); // 👉️ "United States"
console.log(regionNames.of('GB')); // 👉️ "United kingdom"
console.log(regionNames.of('DE')); // 👉️ "Germany"
console.log(regionNames.of('AU')); // 👉️ "Australia"

The Intl.DisplayNames() constructor returns an object we can use to:

• translate a region code to the country's name
• translate a language code to the language's name
• translate a currency code to the currency's display name

The second parameter is an options object.

You can read about all the properties that are available on the options object in this section of the MDN docs.

The Intl.DisplayNames.of() method takes a country code as a parameter and returns a string based on the locale and the provided parameters when instantiating the Intl.DisplayNames object.

# Getting Country names in a different language

If you need the country names in a different language, change the locale when creating the object.

Copied!
const regionNames = new Intl.DisplayNames(['de'], {
  type: 'region',
});

console.log(regionNames.of('US')); // 👉️ "Vereinigte Staaten"
console.log(regionNames.of('DE')); // 👉️ "Deutschland"
console.log(regionNames.of('KR')); // 👉️ "Südkorea"
console.log(regionNames.of('CA')); // 👉️ "Kanada"

# Get a language name from a language code

Here is an example that shows how to get a language name from a language code.

Copied!
const regionNames = new Intl.DisplayNames(['en'], {
  type: 'language',
});

console.log(regionNames.of('en-US')); // 👉️ "American English"
console.log(regionNames.of('en-GB')); // 👉️ "British English"
console.log(regionNames.of('de-DE')); // 👉️ "German (Germany)"

We changed the value of the type property in the options object and got the display names for the language codes.

# Convert a currency code to the currency's display name

You can also use this approach to convert a currency code to the currency's display name for the specific locale.

Copied!
const regionNames = new Intl.DisplayNames(['en'], {
  type: 'currency',
});

console.log(regionNames.of('USD')); // 👉️ "US Dollar"
console.log(regionNames.of('EUR')); // 👉️ "Euro"
console.log(regionNames.of('JPY')); // 👉️ "Japanese Yen"

We set the type property to currency and got the display names of the currencies based on the provided locale.
