Domain Age Checker

Calculate how long a domain has been registered using RDAP registration events — the same authoritative source as modern WHOIS. Enter a domain to see age in years and days, original registration timestamp, expiry date, and current registrar. Helpful for evaluating trust signals on unfamiliar sites, checking renewal deadlines before transfers, and comparing competitor domain longevity. Age reflects the registry's published registration date, which may differ from when a site first went live.

How to Use the Domain Age Checker

Enter a domain name to calculate its age from RDAP registration data and view key lifecycle dates.

  1. Open Domain Age Checker.
  2. Enter the domain name (example.com) without http:// or paths.
  3. Click Check age to query RDAP registration events.
  4. Read the large Domain age banner showing years, days, and total day count.
  5. Review Registered, Expires, and Registrar tiles below the banner.
  6. Compare expiry against today's date if you plan to buy or renew the domain.
  7. Use WHOIS Lookup for full status codes and nameserver details if needed.

Registration events in RDAP

Registries publish lifecycle timestamps as RDAP events — registration, last changed, and expiration. Domain age uses the registration event as the start date, matching industry-standard WHOIS age calculations.

Worked example

  • Shopping site review — a domain registered two weeks ago with heavy discounts warrants extra caution.
  • Renewal planning — expiry six weeks away suggests scheduling registrar renewal or auto-renew checks.
  • Competitive research — compare your brand domain age against competitors for SEO context only, not as a ranking guarantee.

Common mistakes

  • Entering a URL path (example.com/login) — only the hostname is used.
  • Equating domain age with business age — the company may be older than the domain.
  • Ignoring expiry — an aged domain can still lapse if not renewed.

Limitations

Depends on registry RDAP accuracy and availability. Privacy/redaction does not hide dates but some ccTLDs publish limited events. Not legal proof of trademark or business registration.

FAQ

How is domain age calculated?

The tool reads the registration event date from RDAP and computes the elapsed time to today in days and a human-readable years-and-days label.

Why might age differ from archive.org first capture?

Registration date is when the registry recorded the name. A website may launch later, or the domain may have changed owners while keeping the same registration period.

What if registration date is not available?

Some TLDs or redacted RDAP responses omit events. The tool shows an error when Created is missing rather than guessing.

Does old domain age guarantee a site is trustworthy?

No. Age is one signal among many. Compromised, expired-then-reregistered, or parked domains can have misleading histories.

Can I check any TLD?

Any domain with RDAP coverage via the public bootstrap should work. Unsupported or very new TLDs may fail with a not-found error.

Is expiry date shown?

Yes — when the registry publishes an expiration event, it appears alongside registration date and registrar.

Does a recent registration always mean a scam?

Not necessarily — new businesses legitimately register new domains daily. Combine age with HTTPS, reputation, and content review.

Where does the data come from?

Public RDAP via rdap.org, the same protocol used by the WHOIS Lookup tool on this site.

Can I check domain age in bulk?

This interface checks one domain at a time. Export JSON from the result if you need to record findings manually.

Is transferred domain age reset?

Usually not — registration events typically reflect the original creation date, but registry policy varies. Treat edge cases with WHOIS Lookup for full event history.
