What It Is
A country-code top-level domain, or ccTLD, is a domain ending reserved for a specific country or territory. Each one uses a two-letter code, like .us (United States), .uk (United Kingdom) or .de (Germany). Each country sets its own rules for who can register one. Some require a local address or business, while others are open to anyone.
Why It Matters for Your Business
For a business serving customers in one country, a matching ccTLD can signal that you are local. A Chicago bakery would usually choose .com, since most Americans expect it, but a company opening a shop in Canada might add a .ca site. Some ccTLDs, like .co or .io, are popular for reasons that have nothing to do with their country, which can be handy if your .com is taken.
Good to Know
Before buying a ccTLD, read its registration rules. Some countries can change their policies or require you to keep a local presence to keep the domain. Also remember that many people outside that country may not recognize the ending, so think about where your customers actually are before you choose one as your main address.
