About .co
.co is the country-code TLD for Colombia. It was originally restricted to Colombian entities under the country's national academic networking authority, but in 2010 Colombia partnered with .CO Internet S.A.S. to relaunch the TLD as an unrestricted, globally available registration.
The 2010 relaunch positioned .co explicitly as a .com alternative: a two-letter TLD that reads as "company" or "commerce" and provides an option for short, brandable domains when the .com is unavailable. Twitter (then) and several other tech companies adopted t.co and similar .co domains.
.CO Internet S.A.S. was acquired by Neustar in 2014, and the registry passed to GoDaddy Registry after GoDaddy acquired Neustar's registry business in 2020. Registration is open to anyone, with no Colombian residency or business requirement.
