ccTLDs, or Country-Code TLDs, are TLDs that represent a specific geographic location. For example, .us is a ccTLD that represents the United States, while .eu is a ccTLD that represents the European Union.
Unlike gTLDs and ngTLDs, ccTLDs are governed by private or public entities/institutions who set the rules themselves for the ccTLD that they are managing, thus – they do not necessarily need to follow the typical ICANN rules.
Some of these ccTLDs have restrictions such as residency location, type of registrant (individual/business), etc. For example, the .us and .eu ccTLDs require registrants to be located within the USA and the European Union, respectively.
Due to the fact that ccTLDs do not follow the standard ICANN rules especially when it comes to renewal periods, Epik highly suggests that you enable Auto-Renewal as that will ensure that your domains renew in advance of the expiration date to be in compliance with each registry’s renewal period rules.
