.ky is the Internet country code top-level domain (ccTLD) for the Cayman Islands. Registration is limited until September 2, 2015 to residents and registered companies in the Cayman Islands, and a local address is required for the registrant. After September 2, 2015 the .ky extension is available to anyone Worldwide on a first-come first-served basis. The Cayman Islands also has the international three letter code, CYM, and has won a bid to be awarded the .cym domain name in a future expansion of the top level domain space.
In January 2015 the Cayman Islands ICTA announced a partnership with Uniregistry for the operation of the .ky name extension. Uniregistry became the first ICANN accredited registrar to retail .ky names on March 2, 2015.
