Can't Get Your First Choice?
If your ideal domain is taken, these strategies help you find a great alternative.
Try a different TLD
If .com is taken, check .in, .co, .io, .net, or country-specific extensions that match your audience.
Add a keyword
Prefix or suffix with your city, industry, or brand modifier — e.g. get-, my-, shop-, or -hq.
Use a hyphen sparingly
my-brand.com is often available when mybrand.com isn't, though it's slightly harder to communicate verbally.
Register variations too
Once you pick a name, register common misspellings and .net/.org/.in variants to protect your brand.
Domain Availability FAQ
Common questions about checking and registering domain names.
This tool queries the authoritative domain registry for the exact domain name you enter. If the registry returns no registration record, the domain is shown as available to register. If a record exists, the domain is taken.
Results reflect real-time data from the registry at the moment of lookup. Most generic TLDs (.com, .net, .org, .io, .co, etc.) give highly accurate results. Some country-code TLDs may not support instant lookup — for those, check availability directly through the ccTLD's official registry.
If the lookup service could not be reached (network error) or the TLD's registry doesn't support automated queries, the tool returns 'unknown'. In this case, check the domain's availability through your preferred registrar's search tool.
No. This is a read-only lookup — it does not register, hold, or reserve the domain in any way. Domains can be registered by other users within seconds of showing as available. Register immediately once you confirm your chosen name.
This tool checks one domain at a time. For bulk domain searches across multiple names and TLD variations, use the domain search tool in the HostRainbow client area.
