Check how old a domain is from its registration date
Find out exactly how old a domain is: its registration date, age in years, months, and days, when the record was last updated, and when it expires. Check up to 10 domains at once.
Privacy note: your query (just the domain names) is sent to our server, which asks the public RDAP directory. We don't log or store it.
A domain’s age is one of the quickest trust signals available. A shop, bank, or charity whose domain was registered last week deserves a second look — scam and phishing sites almost always run on freshly registered names. An old registration date, on the other hand, shows the name has been held continuously for years, which is useful when vetting a vendor, evaluating a domain you’re thinking of buying, or checking an expired-domain listing. The expiry date matters too: a domain close to expiry may be about to change hands.
For the complete registry record — nameservers, lock status codes, and abuse contact — use the WHOIS Lookup. To see what a domain actually serves today, check its records with the DNS Lookup, or follow where its URLs lead with the Redirect Checker.
From the domain’s registry, via RDAP (Registration Data Access Protocol) — the structured, JSON-based successor to WHOIS that ICANN requires for every generic TLD. Each RDAP record lists lifecycle events; the “registration” event is the date the current registration was created. The tool reads that date, plus the “last changed” and “expiration” events, and calculates the age from today. Because the data comes live from the registry rather than from a third-party crawl or a cached database, it reflects the official record, not an estimate based on when a site first appeared in search engines or web archives.
Domain age measures the current, continuous registration — not the history of the name. If a domain expired, was deleted, and was later re-registered by someone else, the registry resets the registration date to the new creation, even if the name hosted a website twenty years earlier. The reverse also happens: an old domain can be sold or transferred to a new owner without its registration date changing, because a transfer is not a new registration. So an old date tells you the name has been held continuously, not that the same person or business has owned it all along. For ownership history, compare archived snapshots of the site.
Some registries — mostly country-code TLDs (ccTLDs) — answer RDAP queries but leave out the registration event, often for privacy or policy reasons. When that happens the tool still shows what the registry did publish (last update, expiry, registrar) and says plainly that the age can’t be determined, rather than guessing. If a domain returns “not found” entirely, either it isn’t registered or its registry hasn’t adopted RDAP yet. For TLDs we know are missing from IANA’s RDAP bootstrap file (including .de, .ch, .io, .co, .eu, .jp, .it, .es and .us), the tool says it can’t look the domain up instead of reporting “not found”. IANA’s root zone database lists every TLD’s registry so you can check its own lookup page instead.
Not directly. Google has said repeatedly that domain age by itself is not a ranking factor — a two-year-old domain doesn’t outrank a one-year-old one because of the date. What correlates with age is everything that accumulates over time: backlinks, content, brand searches, and a track record without spam. Age is more useful as a trust signal for you: phishing and scam sites are often run from freshly registered domains, so a domain only weeks old is worth a closer look before you hand over a password or payment details. That’s why the tool flags “brand new” domains under three months old.
In whole calendar days in UTC, the timezone registries use. Years and months are counted as calendar units from the registration date, so a domain registered on 14 August is exactly one year older each 14 August. When the registration day doesn’t exist in a later month, the tool uses that month’s last day — a domain registered on 31 January is one month old on 28 February, and one registered on 29 February has its anniversary on 28 February in non-leap years. The total-days figure counts every day, including leap days, and days to expiry are measured from now to the registry’s expiration timestamp.
Your query (just the domain names) is sent to our server, which asks the public RDAP directory and returns the registry’s answer. We don’t log or store the domains you check. Responses are cached for up to an hour so repeated lookups of popular domains are fast. This differs from most of our tools, which run entirely in your browser — checking a domain’s age inherently requires asking its registry. When you check several domains, the tool sends at most two lookups at a time so it doesn’t hammer the registries.
