WHOIS Lookup: Domain Age, Registrar and Expiry Date

How to use it

Enter a domain. Subdomains and URLs are trimmed to the registered domain.
Look up. We query the domain's registry over RDAP, and its registrar when the registry points there.
Read the record. Registrar, dates, age, status codes, nameservers and DNSSEC in one view.

WHOIS and RDAP

WHOIS has been the way to look up who registered a domain since the 1980s. Its replacement, RDAP (Registration Data Access Protocol), returns the same facts as structured data straight from the registry, and ICANN now requires it for every generic top-level domain. This tool uses RDAP, so the answers come from the source rather than a scraped copy.

What you can learn

Domain age. When the domain was first registered. Age is not a ranking factor on its own, but it is a useful sanity check on a link partner or an acquisition target.
Expiry date. When the registration runs out. Let it lapse and the site, email and every link pointing at it go with it. Turn on auto-renew.
Registrar. The company the domain is registered through, and its abuse contact for reporting phishing or spam.
Status codes. clientTransferProhibited is a normal lock that stops unauthorised transfers. redemptionPeriod or pendingDelete mean the domain has expired.
Nameservers. Who hosts the DNS. If they are not who you expect, check with whoever manages your domain.
DNSSEC. Whether the domain's DNS answers are cryptographically signed.

What you will not see

Since GDPR, registrant names, emails and addresses are redacted for almost every domain. To contact an owner, use the registrar's relay form or the contact details on the site itself.

Buying an expired or aged domain?

Check its history before you pay. Look up its current Domain Rating to see whether its backlinks still count, and its DNS records to see what is live on it now.

Some country-code registries do not publish RDAP yet. For those you will need the registry's own WHOIS service.

What you get

Domain age in years and days
Expiry date and days left

Questions

How do I find out how old a domain is?

Enter it above. The registration date comes from the registry's RDAP record, and we show the age in years and days.

How can I see who owns a domain?

For most domains you cannot: owner details are redacted for privacy. You can see the registrar, and contact the owner through the registrar's relay form or the site itself.

What is the difference between WHOIS and RDAP?

Both return domain registration data. RDAP is the modern protocol: structured JSON, served over HTTPS, with consistent fields. ICANN has made it the required service for generic TLDs.

What does clientTransferProhibited mean?

It is a registrar lock that blocks transfers to another registrar without your approval. It is normal and recommended. You remove it in your registrar's dashboard when you want to transfer.

Why is there no result for my domain?

Either the domain is not registered, or its country-code registry does not offer RDAP yet. Several ccTLDs, including some large ones, still only publish WHOIS.
