.co domains
Originally assigned as the country-code TLD for Colombia in the early 1990s, .co was relaunched in 2010 as a global open domain by .CO Internet SAS, a subsidiary of Neustar (later acquired by GoDaddy). The relaunch positioned .co as an abbreviation for company, commerce, and community, and it quickly became one of the most adopted domain extensions worldwide. Colombia retains full use of the extension, and the registry has maintained strong investments in global marketing and brand development.
The .co domain is a globally recognized, open alternative to .com with no registration restrictions. Originally Colombia's country-code TLD, it was repositioned in 2010 as a universal domain for companies, communities, and commerce. It is especially popular with startups, tech companies, and entrepreneurs who find their preferred .com taken, and it carries enough mainstream recognition to serve as a credible primary domain for a wide range of businesses.

Naming guidance
Keep the name before .co short and easy to spell — one or two syllables work best. Avoid constructions where users need to remember the extension is .co and not .com, and invest in clear branding to minimize direct navigation drop-off. Defensive registration of the matching .com is worth considering if the budget allows.

.co vs the alternatives
When to choose a different extension instead.
Choose .com when maximum global trust and recognition are the priority and your preferred name is available.
Choose .io for a developer tool, API product, or technology startup where the .io identity resonates with a technical audience.
Choose .net for a networking, infrastructure, or internet services business that wants a traditional and widely recognized extension.
Choose .inc when emphasizing formal corporate incorporation is more important than domain brevity.
Choose .biz for a small-business site where .com alternatives are needed and a straightforward business identity is sufficient.
