Domain name check across extensions

Type one word and see which extensions already have a registration record.

How to read the result

For each extension the tool asks the registry. If the registry has a record, the name is taken ("Taken") and the expiry date is shown. If it answers that it has no such record, the name shows as "Free?". The question mark is deliberate. A name with no registration record can still be:

  1. Reserved or blocked by the registry.
  2. Priced as a premium name by registrars.
  3. In the process of being deleted, or just registered and not yet shown.

Always confirm at a registrar before you plan a business around a name. The tool does not sell domains and has no affiliate links.

Choosing a name

  1. Keep it short and easy to say aloud.
  2. Avoid hyphens and numbers, which people mistype.
  3. Check that the name is not too close to a known brand: that can lead to a dispute.
  4. Think about the extension your visitors expect: .in for India, .com for global use.

Limits

Some registries do not offer RDAP, such as the ones for .io and .co in the IANA list on the day we read it, so they are left out. The list of extensions is a selection of common ones.

Does it register the name?

No. It only asks the registries.

Why does it ask 13 registries at once?

One question per extension. It may take a few seconds.
