Domain availability checker

How this checker works

For each ending, this tool asks that domain registry’s official RDAP service whether the name exists. If the registry has no record, the name is not registered and is probably available to buy. If it’s taken, you’ll see the registrar and expiry date, with a link to the full WHOIS record.

.ca or .com for a Canadian business?

A .ca tells customers you’re Canadian, and it’s often easier to get a short, local name. To register one you must meet CIRA’s Canadian Presence Requirements, for example being a Canadian citizen or permanent resident, or a business registered in Canada.

Many businesses register both the .ca and the .com of their name and point one at the other, so customers find them either way.

Tips for choosing a name

• Keep it short, easy to spell and easy to say out loud.
• Avoid hyphens and numbers where you can, since people forget them.
• Check that the name isn’t someone else’s trademark.
• Grab the matching social media handles at the same time.

Why some endings can’t be checked

A few registries, such as those for .io and .de, don’t publish an RDAP service, so they aren’t included. The endings listed here all publish official registry data.

Frequently asked questions

How do I check if a domain name is available?

Type the name above. The checker asks each registry directly and shows whether the name is registered on .ca, .com, .net, .org and other endings.

Can I register a .ca domain if I’m not Canadian?

Only if you meet CIRA’s Canadian Presence Requirements, for example through a business registered in Canada or a registered Canadian trademark.

What does “not registered” mean?

The registry has no record of the name, so it is probably available. Reserved and premium names can still be restricted, so confirm the price with a registrar.

Where do I buy a domain once it’s available?

From any accredited registrar. For .ca domains, CIRA lists certified registrars on its website.
