Domain Age Checker

A domain's age is one of the cheapest signals available for triaging risk: a mass-phishing or disposable-spam campaign overwhelmingly runs on domains registered days or weeks before use, because burning a domain and re-registering a fresh one is close to free. Security tooling, spam filters, and browser-vendor reputation systems all weight "how long has this name existed" as one input among many - never the only one, since plenty of newly registered domains are legitimate new businesses or rebrands.

On the SEO side, the idea that older domains rank better circulates widely, but Google has repeatedly stated domain age itself carries little to no direct ranking weight - what correlates with age is usually a longer accumulation of backlinks, content, and user trust signals, which take time to build regardless of the registration date. Age is a proxy for those signals, not a signal on its own.

A registration date is also the fastest way to sanity-check a suspicious link. A checkout page, bank-login clone, or "urgent" support email pointing to a domain registered within the last few days is a stronger tell than most content-based heuristics - legitimate institutions rarely spin up a new domain for a login page.

A domain registry record carries (at minimum) three timestamps, and conflating them is the most common misreading of a WHOIS or RDAP result. The registration date is when the domain was first created in the registry - this is what "domain age" measures. The updated date changes on almost any administrative event: a nameserver change, a registrar transfer, a contact update, or a registrar-side auto-renewal touching the record - it is not a re-registration and does not reset the domain's age. The expiry date is when the current registration period ends; renewing a domain (commonly for one to ten years at a time) pushes this date forward without affecting either of the other two.

A domain can show a very recent "updated" date and still be fifteen years old - that combination usually means a routine renewal or a nameserver change, not a new owner. Age should always be read from the registration date specifically, never inferred from whichever date happens to be most recent in the record.

This tool reads the registration date from the domain's RDAP record - specifically the event in the registry's `events` array whose `eventAction` is `registration` (RFC 9083, the RDAP response schema). RDAP (RFC 9082 for the query protocol) is the structured JSON successor to legacy port-43 WHOIS (RFC 3912), and a client finds the right authoritative server per TLD through the IANA RDAP bootstrap registry (RFC 9224). Age here is computed purely from that one field: current date minus registration date, broken into calendar years, months and days rather than a flat day count, so a domain registered on 15 January several years ago reads as a clean number of years rather than an odd day total.

Coverage follows RDAP adoption, not a universal registry standard. Most gTLDs (.com, .net, .org, .info and the newer generic TLDs) and a growing set of ccTLDs publish RDAP directly. Some ccTLDs still only expose the legacy WHOIS text protocol, or a national web portal that is not machine-queryable at all in a standard way. Where no RDAP endpoint exists for the queried TLD, a registration date may be unavailable even though the domain is registered and live - that gap is a registry limitation, not a fault in the query.

A domain's age describes the registration record only - it says nothing about who currently controls the domain, what content the domain serves, or whether that content changed recently. A fifteen-year-old domain can be compromised, sold, or repurposed for an unrelated site without its registration date changing at all, since a change of registrant contact or nameservers updates the "updated" timestamp, not the original creation date.

It also is not a certificate age, a hosting age, or a DNS-record age. A brand-new website can run on a domain registered a decade ago (a common pattern when a company buys an aged domain for its history), and a freshly registered domain can be fronted by infrastructure that has existed for years. Treat domain age as one data point about the registry record, to be read alongside WHOIS status codes, DNS configuration, and certificate issuance dates - not as a standalone verdict on trustworthiness.
