About the .CK domain
What is the .CK domain?
An important structural feature: it is not possible to register a domain name directly under .ck. The registrant must choose among several available second-level subdomains, with .co.ck being the most common for commercial use. The process requires submitting a Business Registration Certificate or a Trademark Certificate validating the application, and the domain name must be similar to the company name (or a recognizable abbreviation). Processing usually takes one week, the registration period is fixed at 2 years, and two-letter country codes are not allowed as domain names, nor are internationalized characters (IDN) supported.
There is no direct registration under .ck: all registration happens at the second level, mainly under .co.ck (one of 6 available subdomains). A Business Registration Certificate or Trademark Certificate is required, and the name must be similar to the company name or an abbreviation. The registration period is fixed at 2 years.
