.CO is the official country code Top-Level-Domain of Colombia. .CO offers individuals and organizations exciting new options in branding their online presence. Research has shown that .CO is immediately recognizable by registrants around the world to mean "company", "corporation" and/or other types of commercial ventures.

Domain renewal

Although a .CO domain stays in your account for 44 days after a failed renewal before it gets deleted, the registry deactivates the DNS resolving for the domain during this period.

Whois Reseller Branding

The .CO registry allows registrars to insert information about their resellers into the .CO WHOIS records, on a per domain basis. For this purpose, they have introduced two new fields within the whois output, the reseller name and homepage URL, e.g.:

  Domain Name:              SOMEDOMAIN.CO
  Domain ID:                D12345-CO
  Registrar-Reseller Name:  Reseller LLC
  Registrar-Reseller URL:   http://www.resellerhomepage.com
  ...

The reseller's name and URL may be supplied as X-WHOIS-RSP and X-WHOIS-URL parameters within the API commands AddDomain and ModifyDomain.
