Business Name Availability Checker
Updated Sep 2026Enter a business or brand name to check its live domain registration status across .com, .net, and .org - the three extensions with an officially registered public lookup service - pulled directly from public domain registry data.
Domain Availability
Enter a name above and click Check Availability to see live results across .com, .net, and .org.
How It Works
Your name is checked as a domain label against .com, .net, and .org using RDAP (Registration Data Access Protocol), the public standard registries use to publish domain registration status. A live lookup runs for each extension and reports back whether it is currently registered, appears available, or could not be checked.
- Enter the business or brand name you are considering.
- Click Check Availability.
- Review the live status for .com, .net, and .org.
- For any domain marked available, confirm and purchase it directly through a domain registrar before someone else does.
Use Cases
- Checking a shortlisted business name before committing to it
- Comparing domain availability across a few name options
- A quick first check before a deeper trademark and registry search
Frequently Asked Questions
Does this check trademark status?
No. This tool only checks whether a domain name is currently registered. Trademark status is a separate legal question - search your country's trademark office database, or consult a trademark attorney, before committing to a name commercially.
Does this check if the business name is registered as a company?
No. Domain registration and business registration are entirely separate systems. Check your state, provincial, or national business registry directly to see if the name is already in use as a registered company.
Why does a domain sometimes show "Could not check"?
The live lookup to the domain registry did not respond in time or returned an unexpected result. This is not the same as "available" or "taken" - check that specific domain directly through a registrar if you need a definitive answer.
Where does this data come from?
Each check queries RDAP, the public registration-data protocol that domain registries use to publish real-time registration status. It is the same category of data a registrar's own availability checker relies on. This tool checks .com, .net, and .org - the three extensions with an RDAP server listed in IANA's official bootstrap registry - rather than every extension a registrar might offer.
