A Country Code is a short series of letters or numbers that represent a specific country or territory. These codes are often used in various contexts, such as in internet domain names, where the last two letters indicate the country, like .uk for the United Kingdom or .ca for Canada. They help in identifying the origin of products, services, and online content, making it easier to navigate international communications. In addition to internet domains, country codes are also used in international dialing codes for phone numbers. For example, the code +1 is used for the United States and Canada, while +44 is for the United Kingdom. These codes simplify global connectivity by ensuring that calls and messages reach the correct destination.
