# Get Country Flag using ISO Country Code

Wouldn’t it be nice to be able to easily convert a regular ISO 3166-1 alpha-2 country code to its respective Unicode emoji flag?
Here we go...


```
'GB'.toUpperCase().replace(/./g, (char) => String.fromCodePoint(char.charCodeAt(0) + 127397));
``` 

This will turn “GB” into 🇬🇧 (if it displays 🇬​🇧 instead of the British flag, your system does not support emoji flags yet).

You can now write a reusable function that every time you pass a country ISO Code, you get an emoji flag.
```js
const countryToFlag = (isoCode) =>
	isoCode
		.toUpperCase()
		.replace(/./g, (char) => String.fromCodePoint(char.charCodeAt(0) + 127397));
```

To convert from an emoji flag to the country code:


```js
'🇩🇪.replace(/../g, cp => String.fromCharCode(cp.codePointAt(0)-127397) );
``` 
NOTE: This is not supported in IE 11
