A Country Code Top-Level Domain (ccTLD) is a two-letter domain extension assigned to a specific country, territory, or geographic location. Each ccTLD is designated by the ISO 3166-1 alpha-2 standard and is managed locally or by an authorized registry.
Examples include:
.au – Australia
.nz – New Zealand
.uk – United Kingdom
.cn – China
.ca – Canada
.us – United States
.lb – Lebanon
.to – Tonga
While originally intended for use by entities connected to the country, some ccTLDs (like .tv for Tuvalu or .io for the British Indian Ocean Territory) have gained global popularity due to their creative, commercial, or tech-friendly associations.
Some ccTLDs have strict local presence requirements, while others are open for anyone to register.
