A country code top-level domain (ccTLD) is a two-letter domain extension assigned to a specific country or territory. It appears after the final dot in a domain name. Examples include .uk for the United Kingdom and .jp for Japan.

Detailed Explanation of ccTLDs

A country code top-level domain (ccTLD) is a domain extension that represents a specific country, sovereign state, or dependent territory. Each ccTLD consists of two letters and is derived from international ISO 3166 country codes. For example, .de represents Germany, .ca represents Canada, and .fr represents France. These domains are managed by national registries and are subject to local rules and policies. Some ccTLDs require proof of residency or a business presence in the respective country, while others are available globally. ccTLDs play a key role in local branding, search engine optimization (SEO), and geotargeting. They help users identify where a website is based or which region it serves. ccTLDs are an essential part of the Domain Name System (DNS) and are regulated by ICANN.
