DomainTools current TLD-count snapshot for .CO.
.CO share context compared with 392.5M total domain registrations.
Total domain registrations across all TLDs in Q1 2026.
This chart compares .CO with major domain categories using Q1 2026 market data and the latest available count snapshot for the highlighted namespace.
The point for buyers is practical: choose .CO when the extension supports the brand, market, compliance needs, customer expectations, and long-term domain-management plan.
.CO is often read as company, commerce, community, or Colombia, making it useful for concise brand names.
Many startups and product teams review .CO when the matching .COM is unavailable or too expensive.
.CO can be used as a primary site, market-specific site, short redirect, campaign domain, or defensive registration.
Selected public snapshots show .CO remained a multi-million-domain namespace after its global relaunch and startup-market adoption.
Selected public .CO sales examples are shown only when a completed sale includes both an exact domain name and a confirmed amount. These examples are for market context only, not investment advice or a guarantee of future resale value.
A small business, a domain investor, a reseller platform, and a global brand team do not manage domains the same way. Choose the option that matches your situation.
Secure a relevant .CO name before campaigns, products, and customer traffic start moving.
Review availability, renewal handling, transfer status, and account control across many domains.
Connect domain registration, renewal, transfer, and DNS services through reseller APIs.
Get support before registering defensive names, local-market versions, or campaign domains.
If you already own .CO domains elsewhere, transfer decisions should not be based only on one renewal invoice. Check transfer eligibility, ownership access, billing reliability, support response time, API needs, and long-term domain management.
Paste multiple .CO names, remove duplicates, review the count, and continue to bulk registration. This is useful for domain investors, brand teams, agencies, hosting providers, and resellers.
Enter one name per line, with or without .CO. The tool removes duplicates and prepares a clean list for bulk registration.

.CO is the country-code top-level domain for Colombia. IANA lists the Ministry of Information and Communications Technologies of Colombia as the ccTLD Manager, with registration services at registry.co.
.CO can suit businesses, brand owners, agencies, hosting providers, resellers, and regional or global projects that need this namespace and are prepared to follow the applicable registry rules.

Second-level .CO domains are broadly available through accredited registrars. Customers should still provide accurate registrant information and follow registry, registrar, dispute, and acceptable-use policies.
Transfer handling depends on registry policy and the current registrar. You may need to unlock the domain, obtain the Auth Code / EPP code where available, confirm the domain is eligible for domain transfer, and ensure the registrant contact can approve transfer messages.
