How to check if a domain name is available

In Chapter 9, we covered when you need a domain name and why waiting too long to register can cost you. Now that you've decided you want one, the first practical step is checking if the name you have in mind is available. Checking if a domain name is available is straightforward. But there's one part of the process that most people skip, and it can hand your name to a squatter before you ever get to the checkout page.

Here's how to do it right.

How do you check domain name availability?

The simplest way is to go directly to a reputable domain registrar and use their search tool. Type the name you want, including the extension, and the tool tells you immediately whether it's available, taken, or listed as a premium name.

That's it. The search takes seconds. You type in the name, you see the result, and you either register it or move to your next option.

The registrar's search tool checks against the central registry database in real time. If the name is available, no one else owns it right now. If it's taken, someone has already registered it and is paying to keep it active.

Most registrar search tools also show you results for multiple extensions at once. If you search for yourbrandname.com, the tool typically shows you whether .com is available and also shows the status for .net, .co, .org, and a range of other extensions in the same results. That's useful when your first choice is taken and you want to know your options quickly.

Why should you search directly through a registrar?

There are third-party domain lookup tools that let you check availability. Some are comparison sites. Some are aggregators that pull results from multiple registrars. They seem convenient, but there's a real risk to using them.

Some of these tools have been known to trigger what's called domain front-running or domain squatting. When you search for a name on one of these tools, the search is logged. In some cases, a third party monitors those search queries and registers popular names before you get a chance to. By the time you go to a registrar to buy the name you just searched, it's already taken and listed for sale at a markup.

This doesn't happen with every third-party tool, but the risk is real enough that the safest habit is to search directly through a registrar you're willing to buy from. If you search and the name is available, you're one click away from registering it. No gap. No window for someone else to swoop in.

Using a reputable registrar's search tool is also the most accurate way to check. You're querying the registry directly, so the result is current.

What do the domain name availability results mean?

When you search for a domain name, you'll see one of three results.

Available means exactly that. No one owns the name under that extension right now. You can register it. If you want it, register it immediately. Don't close the tab and come back tomorrow. Domain names can be registered by anyone at any time, and common names move fast.

Taken means the name is already registered by someone else. They are paying a yearly renewal fee to hold it. You can't register it in the normal way. You'd need to either contact the current owner, wait for it to expire, or look at alternatives. More on that below.

Premium is the third result you might see. Some domain names are listed as premium by the registry or by a domain marketplace. These are available to register, but at a significantly higher price than a standard registration. The higher price applies at registration and at renewal every year after. A premium domain is still available in the sense that no individual currently owns it, but the registry has priced it above the standard rate. If you see a name listed as premium, check the renewal price before you commit. The yearly cost will be much higher than a regular domain.

What should you do when your first choice is taken?

This is where most people either give up or make a decision they regret later. A few options are worth thinking through carefully.

The first thing to check is whether a different extension works. Your exact brand name might be available as a .co, a .net, a .us, or a country code extension like .ca or .io. Whether a different extension is the right call depends on your audience and what the extension signals. For most US brands targeting a US audience, .com is the strongest choice because it's what people default to when they type a URL. A different extension can work, but it's worth being honest about whether it creates friction. We covered the full picture of what different extensions mean in the article on domain extensions.

The second option is to adjust the name slightly. Adding a short, natural word before or after the name can open up availability. Words like "get", "use", "try", "go", "my", or "the" are commonly used. So "get[brandname].com" or "[brandname]hq.com" might be available even if "[brandname].com" isn't. Keep the addition short. The shorter the domain, the easier it is to type and remember.

Before you settle on a modified version, think about whether the adjusted name still represents your brand clearly. A domain name that confuses people or looks like a workaround might be worth skipping in favor of a cleaner name entirely. The article on whether your domain should match your brand name covers how to think through this tradeoff.

The third option is to contact the current owner and ask if they'd sell. That's where WHOIS comes in.

How do you look up who owns a domain name?

WHOIS is a public database that contains registration information for domain names. When someone registers a domain, their contact details are added to this record. A WHOIS lookup lets you see who owns a domain name, when it was registered, when it expires, and which registrar holds the registration.

You can run a WHOIS lookup through most registrar search tools. After you search for a domain name and see that it's taken, there's usually a link to view the WHOIS record. You can also search WHOIS directly through tools like ICANN's lookup service.

What you find in a WHOIS record depends on whether the owner has privacy protection enabled. Many domain owners use privacy protection, which replaces their personal contact details with the registrar's contact proxy. In that case, the record shows the registrar's information instead of the owner's. You can still reach the owner by sending a message through the proxy contact, which gets forwarded to the actual owner.

If the owner doesn't have privacy protection enabled, you'll see their name, email, and sometimes a phone number. You can contact them directly to ask if they're open to selling.

The WHOIS record also shows the expiry date. If the domain is expiring soon and hasn't been renewed, there's a chance it becomes available again. You can set a reminder to check back around the expiry date, or use a domain backorder service that automatically attempts to register the name the moment it's released.

How do you check availability across multiple extensions at once?

Most registrar search tools show results for several extensions automatically when you search. You type the name and the tool returns a table showing which extensions are available, which are taken, and which are premium.

If you want a broader view, some registrars let you filter the results to show only available options across all extensions they carry. This is useful when you're flexible about the extension and want to see the full range of what's open.

The practical approach is to decide in advance which extensions matter to you. If .com is taken but you'd consider .co or .us, run your search and check both at once. If you'd only accept .com, then the other results are just noise and you can move straight to alternatives.

How do you check if a business name is available beyond just the domain?

A domain name availability check tells you whether the web address is free. It doesn't tell you whether the name is trademarked, whether another brand is using it, or whether your social media handles are available under that name.

If you're choosing a name for a new brand, a domain check is the starting point but not the full picture. You'd also want to run a trademark search through the US Patent and Trademark Office to see if the name is protected. A brand name that someone has already trademarked in your industry can create legal problems even if the domain is technically available to register.

Social media handles are worth checking too. If the name you want is taken as a username on every platform, you'll either need to find a variation or accept that your brand will be slightly inconsistent across channels. Checking handle availability takes a few minutes on each platform and is worth doing before you register anything.

For the purpose of this article, the focus is domain availability specifically. But if you're naming a brand from scratch, treat the domain check as step one of a three-part check: domain, trademark, social handles. All three matter for building a brand that's consistent and legally clear.
