.co is one of the Internet country code top-level domains (ccTLD) and is assigned to the country Colombia. It is regulated by .CO Internet S.A.S., a collaborative effort between Arcelandia S.A. (which has assets in many Internet-related companies) and Neustar, Inc (a world registrar offer managed DNS services for top-level domains). As of July 10, 2010, there is no signup condition for .co top-level domains; any person or company in the world can sign up a .co top-level domain. Many large companies like Twitter use .co top-level domains (e.g. t.co) for URL shortening purposes in social media.


.CO Registration Requirements

.co top-level domain names are available for registration globally through accredited registrars. .CO Internet S.A.S was appointed as the manager for the .CO Top Level Domain through an open acquirement process that happened in the beginning of 2009. .CO Internet accepted the re-appointment approval as the administrator of the .co TLD by ICANN on December 9, 2009, and received official affirmation of the request by the United States Department of Commerce on December 23, 2009. .CO Internet S.A.S. started some new domain policies that are more modern and correspond to the newest accepted practices in the world. The proposed new policies, made by communication with local and worldwide communities, created the possibility for second-level domain names such as widgets.co.
