Is your .com available?

.com is still the most trusted and most typed domain extension, which is why it's usually the first to go. This .com domain checker looks up your name against the official registry and double-checks it with DNS, so a registered domain never shows as free. If your .com is taken, you'll see which of 100+ other extensions are available, grouped by type, and every free domain links straight to registration at Namecheap.

Decades after launch, .com is still the extension people type by default, trust the most and remember best. For many businesses and creators it's the first thing to check. If your exact .com is free, register it quickly: good .com names are rarely available for long.

How our .com check works

We look up your .com against the official registry in real time, then double-check the result with DNS. That second step catches cases where a registry lookup is ambiguous, so a registered domain doesn't show up as available. Every free result links to registration at Namecheap with the domain already filled in.

When the .com is taken

You still have great options. Add a short word that keeps the name recognisable (get, try, use, hq, app), or choose a trusted alternative like .co, .io or .ai. Descriptive extensions such as .studio, .shop or .design can make a name stand out. Domain search checks 100+ extensions in groups so you can compare them in one place.

Match your .com to your socials

A .com works best when it matches your handle on Instagram, TikTok and YouTube. After checking the domain, search the same name across every platform, and claim everything on the same day so your brand is consistent everywhere.
