Domain Age & WHOIS Checker
Look up a domain's age, registrar, and WHOIS details.
Data retrieved live over RDAP, the IETF successor to WHOIS. Availability and fields vary by TLD registry.
About Domain Age & WHOIS Checker
The Domain Age & WHOIS Checker reveals when a domain was first registered, how old it is, when it expires, who the registrar is, and which nameservers it uses. Domain age and history are useful signals when buying an expired domain, vetting a partner or backlink source, or investigating a suspicious site. The lookup runs live over RDAP — the IETF's structured, modern replacement for legacy WHOIS — so results are clean and consistent where the registry supports it. The domain you enter is sent to the responsible registry to fetch its public record; nothing else is stored. Combine it with the Domain Rating Checker to also gauge a domain's authority.
How to Use
- 1Enter a domain (for example, example.com) in the input field.
- 2Press the button to run the lookup.
- 3Read the results, fetched live from the data provider.
Common Use Cases
- Sizing up a site's authority before a link-building outreach
- Vetting a domain's age and history before buying or partnering
- Comparing your Domain Rating against competitors
- Auditing registration, expiry, and nameserver details of a domain
Frequently Asked Questions
How is domain age calculated?
It's the time elapsed since the domain's registration (creation) date in the registry's record. Note that a domain can be registered but unused for years, and that dropped-and-re-registered domains reset this date, so age is a signal, not a guarantee of continuous history.
What is RDAP and how does it differ from WHOIS?
RDAP (Registration Data Access Protocol) is the IETF successor to WHOIS. It returns the same registration data in a structured, standardized JSON format with consistent fields, which is why results are cleaner. Some ccTLDs don't yet expose public RDAP, so a few fields may be unavailable.
Why are some fields missing or redacted?
Registrars redact personal contact details under GDPR and similar privacy rules, and some TLD registries publish only limited data. This tool shows the dates, registrar, nameservers, and status that are publicly available for the domain.
Is the Domain Age Checker free?
Yes — it's free, needs no account or API key, and uses public RDAP data. Lookups are lightly rate-limited and cached to be respectful of registry servers.
Is Domain Age & WHOIS Checker free to use?
Yes. Domain Age & WHOIS Checker is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.
Is my data safe when I use Domain Age & WHOIS Checker?
Domain Age & WHOIS Checker sends only the domain you enter to a third-party data provider to fetch live results. It never asks for personal data, and the domain is not stored beyond a short cache used to speed up repeat lookups.
