Common Questions about .co

What is a .co domain?
.co is a country-code top-level domain (ccTLD) officially assigned to Colombia. Since 2010, it has been marketed globally as a generic alternative to .com, reading naturally as "Company" or "Corporation." Major startups and tech companies worldwide use .co domains as a memorable, short alternative when their preferred .com is unavailable or expensive.
How much does a .co domain cost?
.co domains typically cost $25–$30 per year at standard renewal pricing. Promotional first-year pricing is often significantly discounted—Namecheap's current offer provides up to 67% off. Prices vary slightly by registrar, but .co is generally more affordable than premium TLDs while maintaining strong brand credibility.
Do I need to live in Colombia to register a .co domain?
No. There is no residency or citizenship requirement for .co domains. Unlike some country-code TLDs, .co is open for registration by anyone worldwide—individuals, startups, companies, and organizations regardless of location. This openness is why .co has become so popular for international businesses.
What if my .co domain is already taken?
If your first-choice .co name is taken, try common variations: add a prefix like "get", "try", or "use" (e.g., getyourapp.co), append "app", "hq", or "io" (e.g., yourapp-hq.co), or use an abbreviated version. You can also run a full name search on Namecheckly to check availability across multiple domains and social handles instantly.
Should I also register the .com version of my .co domain?
Yes, if available. Register both .co and .com to protect your brand and avoid confusion. Many users default to .com by habit, and competitors could register it. Namecheap makes managing multiple domain extensions simple under one account, and stacking both extensions signals confidence in your brand.
Is .co good for SEO?
Yes. Search engines treat .co the same as any other TLD—there is no SEO penalty for using .co over .com. What matters most for SEO is your site quality, content, and backlinks. A great site on .co will rank just as well as one on .com. Many successful startups rank highly with .co domains.
