Domain Age Checker
Check any domain's registration date, exact age, registrar and expiry using live RDAP registry data, the modern successor to WHOIS. Free, and your browser talks straight to the registry.
Works for extensions with public RDAP service: .com, .net, .org, .io, .ai, .dev, .app and many more. Some country-code extensions publish no public registration data.
Dates come from the registry's live RDAP record. Dropped and re-registered domains show only the current registration.
How this domain age checker works
WHOIS is being replaced by RDAP, a structured, HTTPS-based protocol run by the same registries. This page sends your domain to the rdap.org bootstrap, which routes the request to the authoritative registry for that extension (Verisign for .com and .net, Public Interest Registry for .org, and so on). The registry replies with the domain's lifecycle events: registration, last update and expiration. Your browser does the lookup directly; CalcWren never sees the domains you check.
Why check a domain's age?
Domain age itself is not a Google ranking factor, but it is a useful trust signal in other contexts: vetting a domain before you buy it, judging whether a site reaching out for a link exchange is established, or sanity-checking a store you have never heard of. A brand-new registration is not proof of anything bad, but combined with other signals it helps you decide how much trust to extend. For what a site looked like historically, pair this with the Wayback Machine.
Frequently asked questions
Where does domain age data come from?
Live RDAP queries to the authoritative registry for the domain's extension, routed through the rdap.org bootstrap. RDAP is the modern successor to WHOIS.
Does domain age affect SEO?
Not directly; Google says it is not a ranking factor. Older domains often rank well because of accumulated content, links and trust, not the date itself.
Why does my domain show an error or no data?
Some country-code extensions have no public RDAP server, some registries omit dates, and unregistered or reserved domains return not found. The tool reports this instead of guessing.
Is the registration date the same as the website's age?
No. It is when the domain name was registered. The site may be much newer, and dropped domains reset the date. Check the Wayback Machine for content history.
Is this domain age checker free?
Yes. Free, no sign-up, and lookups go straight from your browser to the registry. Nothing is logged by CalcWren.
