Expiring .co Domains for Sale
All .co domains are just $99. No negotiation, no hidden fees.
.co is the country code TLD for Colombia, but it has been aggressively marketed globally as a startup-friendly alternative to .com. Since its relaunch in 2010, .co has become a go-to extension for companies that can't get their preferred .com name.
Major companies like Twitter (t.co), Google (g.co), and Amazon (a.co) use .co domains. The extension benefits from its visual similarity to .com — many users won't even notice the difference.
Why .co domains hold value:
- Marketed globally as "company" or "corporation"
- Backed by major tech companies
- Short, clean, professional appearance
- Growing recognition as a legitimate business extension
- Strong aftermarket demand
Who should buy .co domains:
- Startups unable to secure their .com
- International companies
- Short-form URL services
- Companies wanting a clean, modern brand
