.co is a strange success story. Originally the country-code TLD for Colombia (launched 1991), it was rebooted for global use in 2010 under a marketing campaign positioning it as short for "company," "corporation," or "commerce." The launch was surprisingly successful and .co has quietly become the most credible .com alternative in the mainstream TLD hierarchy. Major startups including Angel.co (AngelList), About.co, and Overstock.co have used .co as their primary domain. While it hasn't displaced .com for mainstream use, .co has carved out a legitimate niche for founders whose preferred .com is unavailable.
Key Facts About .co
- Registry operator: .CO Internet (GoDaddy Registry)
- Launched: 1991 (relaunched globally 2010)
- Total registrations: ~3 million
- Best for: Startups wanting .com-like feel when matching .com is taken

Why .co worked when others didn't
Most alternative TLDs launched with heavy marketing and then faded (.biz, .info, .pro). .co succeeded for three reasons:
- Visual similarity to .com. Users often don't notice the missing 'm' at first glance, which can be a feature (looks familiar) or a bug (typos go to .com).
- Meaningful abbreviation. "Co" stands for "company" in most languages, giving it natural commercial association.
- Professional registry operations. Launched with strong technical infrastructure and end-user marketing, including Super Bowl ads.
Current market position
In 2025, average aftermarket .co sales reached $15,199 — about 65% of the average .com. Escrow.com's median .co sale was $3,899 vs. $4,000 for .com, showing that at the mid-market level, .co trades very close to .com value.
Growth has been steady rather than spectacular, which is actually a feature — .co has avoided the speculative boom-bust cycles that hit .xyz and others.

Frequently Asked Questions
Is .co as good as .com?
Close but not quite. For tech/startup audiences, .co is nearly equivalent. For mass-market consumer products, .com still has better trust and type-in patterns.
Will users confuse my .co with .com?
Some will. The typo problem is real but manageable — many .co sites also own the .com redirect as a defensive measure.
How much does a .co domain cost?
Registration ranges from $12 to $30 per year. Some registrars use promotional first-year pricing and higher renewals — check renewal rates before committing.
Can I use .co for any kind of business?
Yes — despite being technically Colombia's ccTLD, .co is open globally with no residency requirements.
