Demand remains strong for .com and .co.countrycode domains, but many desirable short names are already registered.

As of 2026, Verisign reported 166.6 million .com domains, while Nominet reported more than 8.7 million .co.uk domains. Many other ccTLDs also have millions of registered domains. Together, these figures show the scale of familiar domain namespaces. .co.com brings together the “co” used in many country-code domains and the widely recognized .com ending.

For registrars, .co.com provides another relevant result in the customer’s existing domain search. It can help customers continue toward a name that fits when the exact .com they want is unavailable.

• When the preferred .com is already registered
• When the brand or search terms do not clearly point to a different extension
• As a relevant complementary option at checkout

69 countries offer .co.countrycode domains.

Businesses use .co.countrycode domains such as .co.uk and .co.jp to reach customers in specific markets. When a preferred name is already registered in .com or a country-code namespace, acquiring it from its current owner may mean paying an aftermarket price. If the same name is available in .co.com, customers have another option: register it through their registrar at the registrar’s regular price.

For registrars already using CentralNic, onboarding is simple, and integration follows the familiar EPP process using their existing connection and code.

• First-come, first-served registrations
• No auction process
• Flat per-year registry pricing
