HTML Country Codes

HTML Country Code can be defined using the attribute lang on the element <html> to specify the language's country of a web page, which is being used by search engines and browsers.

Country code can be provided as an extension to language code, so it cannot be specified without a language code.

The country codes are two-character codes that determine the language's country.

In the below example, the language code en for English and the country code US for the United States.

<html lang="en-US">
