How old is this website?
Type any domain to see when it was registered, how many days ago that was, and who it is registered through.
Free, no account. We show registration facts only, never owner details.

What this checks
Every domain name is held in a registry, and the registry keeps a public record of it: when it was first registered, when it expires, which registrar manages it, its status codes and the name servers it points to. For decades that record was read with WHOIS, a plain-text protocol from the early internet.
Its replacement is RDAP, the Registration Data Access Protocol, which returns the same facts as structured data over HTTPS (RFC 9083). ICANN now treats RDAP as the definitive source for generic domains such as .com. We ask RDAP first and fall back to a registry's WHOIS server where it has no RDAP service.
Why other WHOIS tools go blind. Since January 2025, ICANN has let registries of generic domains switch the old WHOIS service off, and many newer extensions have. A lookup tool that still only speaks WHOIS gets nothing back, often at the exact moment a domain expires and is being deleted. We read the registry's RDAP record, so an expiring domain stays visible, with its status and estimated drop date, until the day it is released.
The age shown is counted from the registration date in that record, to today.
Why age matters for AI
A young domain is easy to dismiss as a competitor. AI assistants with web search give it no such handicap. When ChatGPT, Claude, Gemini or Perplexity searches, it reads pages it finds right now and answers from them, so a page that is indexed, clear and specific can be quoted within days of going live. The two routes, memory and live search, are explained in AI memory vs live search.
That is why we built this check. When aipozi looked at who ChatGPT recommended for its founder's own products, several of the sites it cited were two weeks to four months old, many of them built with AI tools. A registration date is the quickest way to tell whether the business an assistant just named has been around for ten years or ten days.
A young domain is not a bad sign on its own. It tells you that the competition for an AI's answer is open, and that a new rival can take your place quickly. Here is how to check whether ChatGPT recommends you, by hand or with aipozi.
Questions
About domain age, WHOIS and RDAP, and why we built this.
Is it free?
Yes. There is no account, no email and no card. Type a domain and you get its registration facts. We limit how many checks one network can run in a few minutes so the registries keep answering everyone.
Why is the owner hidden?
Since 2018, when Europe's GDPR came into force, registries and registrars have redacted the personal details of most domain owners from public records. We go further and never show owner details at all, even when a record still has them. You see the registration facts: dates, registrar, status and name servers.
What is RDAP?
RDAP, the Registration Data Access Protocol, is the modern replacement for WHOIS. It returns the same registration facts as structured data over HTTPS, and it is the official way to look up generic top-level domains such as .com. Where a country registry offers no RDAP, we fall back to its WHOIS server.
Why does domain age matter for ChatGPT?
Because it often doesn't, and that is the point. With web search on, ChatGPT and the other assistants answer from pages they find today. A site registered a few weeks ago can be read and recommended if it is indexed and answers the question clearly. aipozi has seen sites two weeks to four months old cited by ChatGPT ahead of established businesses.
Is the registration date when the website launched?
Not always. It is when the current registration began. A domain can be bought years before a site goes live, and a domain that lapsed and was bought again usually starts a new date. Treat it as the earliest the current owner could have had the site.
Why does a domain show no date, or not found?
Some country registries don't publish a creation date at all, and a domain that has never been registered, or has expired and been released, has no record to show. A brand-new registration can also take a little while to appear.
