Domain Availability

Find out instantly if a domain name is available to register by checking root registries.

How accurate is this check?

This tool performs a real-time query directly against the authoritative WHOIS registries. It is highly accurate and does not use cached registrar APIs which are sometimes delayed or incorrect.

Please note that highly desirable domains may be snatched up by drop-catchers or algorithms within milliseconds of becoming available if they were recently expired.

Our Domain Availability Checker queries WHOIS to determine whether a domain is registered, available, or in one of the intermediate states — expired but recoverable, reserved, or premium — that a simple available or taken answer would miss.

What is Domain Availability?

A domain is available when no registration record exists for it at the registry, meaning anyone may register it.

The binary framing is misleading, though. A domain can also be registered but expired and in its grace or redemption period, where it is unavailable now but may be released shortly. It can be reserved by the registry and never offered to the public. It can be classified as premium, technically available but priced far above standard rates. Or it can be registered and parked, with an owner who may be willing to sell.

Availability is also checked in two different ways. A WHOIS query is authoritative but slower; a DNS query is fast but only tells you whether the domain resolves, which is not the same thing at all. A registered domain with no DNS records looks available to a DNS check and is not.

Available means no registration record exists at the registry
Expired domains may become available after grace and redemption
Registry-reserved names are never offered publicly
Premium domains are available but priced above standard rates
A DNS lookup does not reliably indicate availability

Why Domain Availability Matters

For anyone launching a brand, availability across the relevant TLDs shapes the naming decision. Discovering after launch that the .com is held by a competitor, or that a typo variant is registered by someone else, is expensive to unwind.

Defensive registration is the other half. Attackers register lookalike domains — typo variants, hyphenated forms, alternative TLDs — specifically to impersonate established brands in phishing. Knowing which of those are still available lets you register the plausible ones yourself, which is far cheaper than dealing with an active impersonation campaign.

Availability across TLDs shapes brand naming decisions
Lookalike domains are registered by attackers for phishing
Defensive registration is cheaper than responding to impersonation
Expired domains carrying residual traffic are actively targeted
Checking before launch avoids costly renaming later

How This Availability Checker Works

The tool queries the authoritative WHOIS server for the TLD and interprets the response.

Validates the domain input against format and SSRF safety checks
Identifies the authoritative WHOIS server for the TLD
Queries that server for a registration record
Interprets the response, distinguishing available from expired and reserved
Reports the registration status with any relevant dates

How to Use the Availability Checker

Enter the domain name including the TLD you want to check
Run the check to query WHOIS
Review whether the domain is registered, available or in another state
For registered domains, check the expiry date to see whether it may be released
Register promptly if the domain matters — availability changes constantly

Understanding Your Availability Results

Registration status is more nuanced than available or taken:

Field / Value	Meaning
`Available`	No registration record exists. The domain can be registered now, at standard pricing unless the registry classifies it as premium.
`Registered`	An active registration exists. The WHOIS record shows the registrar and expiry date, though registrant details are often masked by privacy protection.
`Expired`	Registered but past its expiry date. It sits in grace or redemption and may be released later, or may be renewed by the current owner at any point.
`redemptionPeriod`	The original owner can still recover it for a substantial fee. Roughly 30 days, after which pending delete begins.
`pendingDelete`	The final five-day stage before release. Desirable domains are usually caught by drop-catching services within seconds of becoming available.
`Reserved`	Held by the registry and not offered publicly. Common for single-character names, geographic terms and strings reserved under registry policy.
`Premium`	Available to register but priced well above standard rates, set by the registry based on the perceived value of the string.

Common Problems & How to Fix Them

Registration and DNS are independent. A domain can be registered with no DNS records configured, no hosting, or nameservers that do not answer.

Check the nameservers and DNS records to see what is actually configured. A registered domain that does not resolve is often parked, held defensively, or abandoned but not yet expired.

The usual causes are registry reservation, premium classification, or a very recent registration that WHOIS has not yet reflected.

Check the registrar for a premium price, which can be many times the standard rate. If the registry has reserved the string, no registrar can sell it regardless of what an availability check suggests.

Most expired domains are renewed during grace or redemption. Of those that do drop, valuable ones are caught by drop-catching services within seconds of release.

Backorder services will attempt to register it the moment it drops, though there is no guarantee. For a domain you genuinely need, negotiating with the current owner is often more reliable than waiting.

Typo variants and alternative TLDs of established brands are routinely registered, sometimes speculatively and sometimes for impersonation.

Register the plausible variants you can while they are available. For those already taken and being used in bad faith, the UDRP dispute process exists, though it takes months and costs money — which is why defensive registration is the cheaper path.

Some registries rate limit queries, restrict output, or return inconsistent formats. Privacy regulation has also reduced what is published.

Try RDAP, the structured successor to WHOIS, which many registries now serve and which returns consistent JSON. For country-code TLDs, the registry own lookup page is often the only reliable source.

Best Practices

Check availability across every TLD relevant to your market before committing to a name
Register the obvious typo variants of your main domain defensively
Secure your brand in the major TLDs even if you only use one
Register promptly once you decide, since availability changes constantly
Verify with WHOIS rather than relying on whether the domain resolves
Check expiry dates on registered domains you are interested in
Keep a record of every defensive registration so none is allowed to lapse

Security Recommendations

Register plausible lookalike domains defensively, since they are the raw material of brand impersonation phishing
Monitor newly registered domains resembling your brand, as registration is the earliest warning of a campaign
Be cautious with availability checking services that may register the names you search for, a practice known as front running
Point defensive registrations at a holding page rather than leaving them unconfigured
Publish a restrictive SPF and DMARC record on defensive domains so they cannot be used to send mail
Audit your portfolio regularly, since a lapsed defensive registration becomes available to exactly the people you registered it to block

Frequently Asked Questions

Query WHOIS for the domain. If no registration record exists, it is available. Checking whether it resolves in DNS is unreliable — a registered domain with no DNS records will appear available when it is not.

It may be reserved by the registry, classified as premium with a much higher price, or registered very recently in a way WHOIS has not yet reflected. Check with a registrar for the actual price and status.

A domain the registry has classified as high value and priced well above standard rates. It is genuinely available, but the registration and often the renewal cost considerably more than an ordinary name.

After grace, redemption and pending delete — typically around 65 to 75 days after expiry, though it varies by TLD. Most are renewed before release, and valuable ones that do drop are usually caught within seconds by drop-catching services.

For an established brand, yes. Typo variants, hyphenated forms and the major alternative TLDs are cheap to register and expensive to fight over later. Attackers use exactly these variants for phishing.

The practice of registering a domain someone has just searched for, then offering it back at a higher price. Reputable registrars and lookup services do not do this, but it is a reason to register promptly once you have decided.

Only by buying it from them, or through a UDRP dispute if it was registered in bad faith against a trademark you hold. Disputes take months and cost money, which is why registering defensively in advance is usually cheaper.
