.co
The .co domain is the country code top-level domain (ccTLD) for Colombia. It is widely marketed as a global alternative to .com and is operated commercially (registry services associated with GoDaddy Registry / .CO Internet).
Overview
Although assigned to Colombia, .co is unrestricted for global registration and is positioned as shorthand for “company” or “corporation.”
Usage
Startups and tech brands use .co when the matching .com is taken. It is more expensive than typical new gTLD promos but shorter and more brandable than many alternatives.
