How to check if a domain name is available (and what to do if it's taken)

You have a name you like. Before you order signs or business cards, make sure you can get the domain. The check takes a minute and costs nothing.

Below: how to check if a domain name is available, what each result means, how to see who owns a taken name, what happens when a domain expires, how to buy one safely, and how to check many names at once with our free domain name generator.

The quick way to check domain availability: search at any registrar

A registrar is a company that sells domain names. For generic extensions like .com, registrars are accredited by ICANN, the nonprofit that coordinates the domain name system, which publishes a list of accredited registrars. GoDaddy, Namecheap and Cloudflare are three examples.

1. Go to a registrar's website and open its domain name search.
2. Type the full name with its extension, for example yourbusiness.com.
3. Read the result: available (with a price), taken, or premium.
4. If it's available and you're sure, register it now. The front running section below explains why.

Behind the search box, the registrar asks the registry that keeps the master list for that extension. IANA's root zone database shows who runs each one; for .com, it's VeriSign Global Registry Services. To ask the registry yourself, open https://rdap.verisign.com/com/v1/domain/yourbusiness.com in a browser (Verisign's free lookup). A page of data means the .com is taken; an error 404 means no one holds it.

What "available", "taken", "premium" and "parked" mean

Result	What it means	What you can do
Available	No one holds it. Released names go first come, first served.	Register it now. Check the renewal price, not just the first year.
Taken	Someone holds it, with or without a website on it.	Look up the owner, try another name or extension, or make an offer.
Premium	For sale now, at a higher price set by the registry or by an owner reselling it.	Compare first-year and renewal prices first.
Parked	Registered, but showing a holding page, ads or a "for sale" notice.	Look for a sale notice or contact the owner. Pay only through escrow.
Expired	The term has ended, but the owner can still renew or restore it for a while.	Wait. You can't register it until it's released.

Premium names sometimes renew at the premium price too, so ask before you buy. ICANN requires registrars to display their renewal fees clearly on their website.

Parked names often show pay-per-click links that earn the owner money when visitors click. Many are for sale. Some aren't, at any price.

How to see who owns a taken domain

Use ICANN Lookup, a free public service whose results come directly from registries and registrars in real time. It runs on RDAP, which replaced WHOIS and has been the definitive source for registration data in generic extensions since 28 January 2025.

You'll usually see the registrar, the creation and expiry dates, name servers, and status codes such as clientTransferProhibited, which ICANN's status code guide explains in plain words.

What you often won't see is the owner's name, address or phone. Under ICANN's Registration Data Policy, in effect since 21 August 2025, registrars hide these where the law requires it, and may in other cases. When they do, they must publish an email address or a web form link so you can still reach the owner. Some owners also use a privacy service.

Need the hidden data for a legal reason, such as a trademark dispute? ICANN's Registration Data Request Service is built for people with a legitimate interest.

What happens when a domain expires

For generic extensions like .com, ICANN's rules give the owner several chances to keep the name. Country extensions, like .uk or .ca, can set their own.

1. Reminders. The Expired Registration Recovery Policy requires renewal reminders about one month and one week before expiry, and one more within five days after.
2. Auto-renew grace period. The registrar can delete the name at once or hold it for 1 to 45 days while the owner can still renew. Depending on the registrar's terms, others may get a chance at it in this window. Before deleting, the registrar must cut off the website and email for up to eight days as a final warning, and the Expired Domain Deletion Policy has it cancel an unrenewed name by the end of this period.
3. Redemption grace period. Once deleted, the name gets 30 days in which the old owner can have it restored, often for an extra fee.
4. Pending delete. Then come 5 days of pending delete, and the name is released, first come, first served.

So a name can stay out of reach for as long as 80 days after it expires (up to 45, plus 30, plus 5), and the owner can take it back at almost every step. "Backorder" services try to catch names as they're released, but ICANN's security committee has warned that people often wrongly assume a backorder guarantees the name.

Buying a domain from its current owner

Some taken names are listed on domain marketplaces, often called the aftermarket. For others, write to the owner through the email address or web form in ICANN Lookup. Before you pay:

• Check for trademarks. Every .com registration includes ICANN's dispute policy (UDRP), which makes checking for conflicts with others' rights the owner's job. If a trademark holder proves the name is confusingly similar to their mark and was registered and used in bad faith by someone with no legitimate interest in it, a panel can cancel it or transfer it to them. Our guide on how to name your business covers trademark checks.
• Use escrow. A neutral escrow service, or the marketplace's own checkout, holds your money until the domain is in your account. Never wire money to a stranger.
• Get it into your name. The seller moves it to your account at the same registrar, or transfers it to yours with a transfer code. Some transfers have waiting periods, which ICANN's transfer FAQ explains.
• Watch for scams. Ignore unsolicited emails warning that someone is about to register "your" name, or asking you to renew through a link. ICANN says it doesn't process registrations or collect fees from registrants, and its list of registrant rights says your registrar shouldn't use deceptive notices or hidden fees. Go to your registrar directly instead.

Front running: why "search now, buy later" is risky

Some people search for a name, come back days later, find it registered and suspect the site they searched on. ICANN's Security and Stability Advisory Committee calls this domain name front running: using someone's availability check to register the name before they do.

What ICANN has said about it:

• 2008: after reviewing 120 claims, the committee had insufficient information to conclude that companies running name searches practiced it in any appreciable measure. It found other plausible explanations for every case, without ruling front running out.
• 2009: a study ICANN commissioned ran more than 600 tests on leading registration and availability-checking sites and found no evidence of front running.

The usual explanations are ordinary: people want the same popular words, and lapsed names get registered again. Still, the committee's advice holds: a search shows interest and competition for names is intense, so register the name at the time you check it.

The safe move: register a name you like right away, at a registrar you trust, such as one on ICANN's accredited list. An unused name is a small, known cost. Buying it back may not be.

Check many names at once

Checking names one by one is slow when you're still choosing. Our free domain name generator does it in one pass: type a word or two about your business, get name ideas, see which ones have the .com free, and go register the one you like.

After you register, turn on auto-renew, keep the registrar lock on, use two-step sign-in on your registrar account, and check that no one can send email pretending to be your domain.

FAQ

Is it free to check if a domain name is available?

Yes. Searching at any registrar costs nothing, and so does ICANN Lookup. You only pay when you register a name.

Can I find out who owns a domain name?

Partly. ICANN Lookup shows the registrar, the key dates and the status. The owner's name, address and phone are often redacted, but the registrar must publish an email address or a web form so you can reach them.

When will a taken domain become available?

Only if the owner stops renewing it. After it expires there can be a grace period of up to 45 days, a 30-day redemption period and 5 days of pending delete, and the owner can renew or restore it during most of that time.

Should I register a domain as soon as I find it?

If you're serious about the name, yes. ICANN's security committee suggests registering a name at the time you check it, because a search shows interest and others may want the same name.
