Domain WHOIS / RDAP Lookup
Look up a domain's registration record: who the registrar is, when the domain was created, when it expires and what its status codes mean. Paste a domain or an email address.
Works for .com, .net, .org, .info, .xyz, .online, .shop, .app, .dev, .ai and hundreds of other endings, plus .uk, .ca, .au, .fr, .nl, .in, .is and more. Only the domain name is sent, straight to the registry.
Why is the owner's name hidden?
Since the EU's GDPR took effect in 2018, most registries and registrars no longer publish the name, address, email or phone number of the person who owns a domain. The record shows "redacted for privacy" instead. That is normal and is not a sign that anything is wrong. Some business domains still show the organisation's name and country. To contact an owner, use the registrar's contact form or the abuse contact shown in the results.
What the dates and statuses tell you
| What you see | What it means |
|---|---|
| Created less than 30 days ago | A brand-new domain. Common for legitimate new businesses, but also for spam, phishing and fake signups. On a signup or lead list, it's a red flag. |
| Expires date has passed | The domain is in a grace period or about to be deleted. Its email will stop working soon, if it hasn't already. |
client transfer prohibited | A normal lock set by the registrar to stop the domain being stolen. Most domains have it. |
redemption period or pending delete | The domain expired and is being deleted. It will soon be released for anyone to register. |
client hold or server hold | The domain has been switched off and doesn't work in DNS, often for non-payment or abuse. |
The full list of codes and what they mean is in ICANN's EPP status codes guide. The tool explains every code it finds.
WHOIS and RDAP: what's the difference?
WHOIS is the old way of looking up who registered a domain. RDAP (Registration Data Access Protocol) is its modern replacement: the same registration database, but with structured data, secure https connections and consistent dates. Since January 2025, ICANN no longer requires generic domain registries such as .com and .org to run the old WHOIS service, so RDAP is now the official source. This tool finds the right registry for each ending from IANA's RDAP list and asks it directly.
Which endings work?
Almost every generic ending (.com, .net, .org, .info, .biz, .xyz, .online, .shop, .app, .dev and hundreds more) works, because their registries must allow lookups from web pages. Country endings vary. This page can look up .uk, .ca, .au, .fr, .nl, .in, .is, .br, .no, .pl, .cz and .fi, if the registry answers browser requests. Some popular country endings, such as .de, .io, .co and .me, don't have an RDAP service listed with IANA yet, so the tool tells you where to look instead. It never guesses or makes up data.

What the WHOIS / RDAP lookup does
Every registered domain has a record in its registry's database: who sold it (the registrar), when it was created, when it expires, its status codes and its name servers. This tool reads that record over RDAP, the modern replacement for WHOIS, straight from the registry, and explains it in plain English. It also gives a quick verdict on the domain's age, which helps you judge a signup, a lead or an email from an unknown company.
Benefits
- From the sourceThe data comes straight from the registry that runs the domain ending, not from a copied database.
- Domain age at a glanceSee when the domain was created and how old it is, with a warning for brand-new domains.
- Expiry warningsExpired, expiring soon, in redemption or about to be deleted, all flagged clearly.
- Status codes explainedCodes like clientTransferProhibited and redemptionPeriod are translated into plain English.
- Registrar and abuse contactSee which company the domain was registered through and where to report abuse.
- Name servers and DNSSECSee which DNS service the domain uses and whether it is signed.
- Email address or domainPaste an address like [email protected] and the tool looks up example.co.uk.
- Honest when it can'tIf a registry has no RDAP service or doesn't answer browsers, the tool says so and links you to the registry's own record.
Who it is for
- A list owner checking whether a signup came from a domain registered last week.
- A small-business owner checking when their own domain expires.
- Someone who received an email from an unknown company and wants to know how long it has existed.
- A domain buyer checking the status and expiry date of a name they want.
How to use it
- Type a domain, or paste an email address or website link.
- Press Look up domain.
- Read the verdict, then the registrar, dates, name servers and status codes.
- Use View the raw record to see everything the registry published.
Your privacy
Your browser fetches IANA's public list of registries and then asks the registry for the domain you entered. Only the domain name is sent. ListaFix doesn't receive or store your lookups.
Frequently asked questions
Is this the WHOIS database?
It reads the same registration database that WHOIS uses, through RDAP, the official replacement for WHOIS. For generic endings like .com, RDAP is now the authoritative source.
Why can't I see who owns the domain?
Most registries and registrars hide personal contact details for privacy, as required by laws like GDPR. The record shows the registrar and dates but marks contact details as redacted. Business domains sometimes still show the organisation and country.
What does "Not registered" mean?
The registry has no record of the domain, so it is most likely available to register. Some names are reserved or sold as premium names, so check with a registrar. An email address at an unregistered domain can't work.
Why doesn't my .de, .io or .co domain work?
Those registries don't have an RDAP service listed with IANA, so there is no standard way to look them up from a browser. Use the registry's own WHOIS page (for example, DENIC for .de).
Why did the lookup fail for a country ending?
Some country registries don't send the web headers that let a browser read their answers, or limit how many lookups they answer. The tool then links to the registry's record so you can open it directly.
How can a domain's age help with my email list?
Fake signups, spam traps and scam sites often use domains registered days earlier. A very new domain on a signup or lead list is worth a second look. It doesn't prove an address is fake, so check the mailbox with Veml as well.
