Get the exact registration age of any domain in years and months, plus the creation date, expiry date, and registrar. Newly-registered domains are massively over-represented in phishing campaigns — domain age is one of the highest-signal single fields in security analysis.
The Domain Age Checker queries the authoritative WHOIS server for any domain and surfaces the age-relevant fields: exact age in years and months, creation date, last-updated date, expiry date, and registrar. The full WHOIS response (nameservers, DNSSEC, registrant data) is available via the WHOIS Lookup tool when you need it; this tool strips down to the focused question "how old is this domain?" with a clean answer.
What is different about this tool: computed age, not just dates. Most WHOIS lookups give you the Creation Date and leave the maths to you. This tool computes the age in years and months at query time so you see 3 years, 7 months instead of 2022-09-15. For phishing analysis, fraud investigation, and competitive intelligence, the age figure is the actionable signal — and seeing it pre-computed at the top of the result is the difference between a 2-second decision and a 30-second mental subtraction.
How it works under the hood
When you submit a domain, the tool extracts the registrable hostname, identifies the TLD, and queries the authoritative WHOIS server for that TLD on port 43. The response is parsed for the Creation Date, Updated Date, Registry Expiry Date, and Registrar fields. Creation Date is then converted via PHP's strtotime() and the age is computed as years + months from now.
Why the age figure matters more than the date. Phishing operators register domains, run a campaign for 1-3 days, and walk away. Fraud rings register domains in batches and burn through them at scale. The vast majority of attacker-owned domains are under 90 days old at the time they're being used against you. "Created 2024-12-08" requires you to subtract from today; "4 months" lets your brain trigger the right pattern-match instantly.
Caching and rate. Results cache for one hour via WordPress transients keyed by domain. WHOIS servers do enforce per-IP rate limits, and the cache means our infrastructure makes one query per domain per hour regardless of user volume.
What this tool does NOT do. It does not show full WHOIS data (use the WHOIS Lookup tool for nameservers, registrant org, DNSSEC, etc.). It does not query historical WHOIS to show ownership changes (paid services like SecurityTrails do that). It does not query .uk, .de, .fr or other ccTLDs that use non-standard WHOIS protocols — for those, use the registry's own lookup interface.
Five real-world use cases
Vet a suspicious domain in 5 seconds
An email arrives from a domain you don't recognise, a colleague forwards a link, or a payment request comes from an unfamiliar billing address. Run the domain through this tool. If it's under 90 days old, treat as suspicious by default — combine with the URL scanner and WHOIS to make the call. Domains under 30 days for anything claiming to be an established business are a near-certain red flag. This single check is the fastest first-pass triage in security ops.

Verify a new business is actually new (or actually established)
A vendor pitches you and claims to be "established since 2015". Check their domain age. If the domain is 8 years old, the claim is at least plausible from an infrastructure standpoint. If the domain is 3 months old, the claim is contradicted by the WHOIS record — either they re-branded (worth asking about), they migrated from a previous domain (worth verifying), or they're misrepresenting the company history. Domain age is one of the cheapest pieces of vendor due diligence.
Value a domain before purchase
Aged domains carry SEO value because Google's ranking algorithms factor in domain age (alongside content quality, backlinks, and other signals). Before paying for an aged domain, run this tool to confirm the seller's claim. A domain marketed as "15 years old" that shows 2 years in the WHOIS has been re-registered after lapsing — the SEO history is gone and the value is closer to a fresh registration. The reverse also matters: a 20-year-old domain with consistent registration is genuinely valuable for branding and search.
Bug bounty: confirm in-scope assets via age clustering
When recon expands a target's surface area, registration date clustering helps confirm what's actually owned by the target organisation. A handful of domains all registered within the same week often signals coordinated infrastructure rollout — useful for confirming in-scope assets and identifying related domains that might also be in scope. Combined with WHOIS Lookup for the full registrant data, this is fast triage during the discovery phase.
Monitor competitor product launches via domain registration
Competitive intelligence: marketing domains for upcoming products often get registered weeks or months before public announcement. Periodic checks on plausible product-name domains can give you advance warning of competitor launches. Note that registrar-side privacy redaction now hides registrant details on most domains — so creation date is usually the only useful field, but creation date alone is often enough to time your own announcements.
Common mistakes & edge cases
Confusing domain age with website age
Domain age tells you when the registration was created. Website age tells you when actual content was first served. A 10-year-old domain might have only had a real website for the last 6 months (someone bought the aged domain and built something new on it). For website-age analysis, cross-reference with the Wayback Machine — when did the domain first index with substantial content?
Treating Creation Date as immutable
A domain that lapses and gets re-registered shows the new Creation Date, not the original registration. So a domain that "existed" for 20 years on the public web but lapsed last year and was re-bought reads as 1-year-old in WHOIS. From a security perspective the new reading is correct (different registrant, no continuity), but for valuation purposes you need to check Wayback for the historical record.
Treating old age as proof of safety
Old domains can be compromised and used for phishing too — sophisticated attackers buy aged domains specifically because they bypass new-domain filters. Age is one signal among many, not a clean pass/fail. For high-stakes decisions (clicking a link, processing a payment), combine age with WHOIS, DNS posture, SSL issuer, and URL-pattern checks rather than relying on age alone.
Ignoring the Updated Date
An old Creation Date with a recent Updated Date often signals the domain changed hands or had infrastructure migration. Updated Date within the last 30 days plus suspicious DNS or content is a higher-attention combination than either signal alone. The full WHOIS Lookup surfaces this field; this tool focuses on age but the Updated field is right there in the response too.
Querying ccTLDs and getting empty results
Country-code TLDs (.uk, .de, .fr, .nl, .au, .ru, etc.) often use non-standard WHOIS protocols. The tool may return empty results for these. For .uk specifically, use Nominet's WHOIS at nominet.uk/whois/; for .de use denic.de; each registry maintains its own lookup interface.
Using age as your only filter at scale
If you build automated pipelines (like email security rules) that block all domains under 30 days, you'll get false positives — legitimate new businesses, marketing campaign domains, and ad redirect chains will all be flagged. The right pattern is friction not block: require extra verification (CAPTCHA, manual review, secondary auth) for new-domain interactions, rather than refusing them outright.
Frequently Asked Questions
Paste the domain into the checker above. The tool returns the age in years and months, plus the creation date, expiry date, and registrar. The check uses authoritative WHOIS data and takes about 2 seconds.
Phishing operators register domains, run a campaign for 1-3 days, and walk away. The vast majority of attacker-owned domains are under 90 days old at the time they're being used. Filtering inbound URLs by domain age catches a substantial fraction of phishing without any other threat intelligence.
Accurate to the day for gTLDs (.com, .net, .org, .io, etc.) where the WHOIS Creation Date field is reliable. Less reliable for ccTLDs that use non-standard WHOIS — the tool may return empty or partial data for .uk, .de, .fr, etc. For those, use the registry's own lookup interface.
Domain age is when the registration was created. Website age is when content was first served on the domain. A 10-year-old domain might have a brand-new website on it (someone bought the aged domain and built fresh content). For website history, cross-reference with the Wayback Machine.
Yes, if the domain lapses and gets re-registered. The new registration shows the new Creation Date, not the original. From a security standpoint this is correct (different registrant, no continuity), but for valuation purposes the new date understates the domain's history. Cross-check with Wayback for the full picture.
No. Sophisticated attackers buy aged domains specifically because they bypass new-domain filters. Age is one signal among many — for high-stakes decisions, combine age with WHOIS, DNS posture, SSL issuer, and URL-pattern checks rather than relying on age alone.
Under 30 days is a strong red flag for anything claiming to be an established business. Under 90 days warrants caution and additional verification. Above 90 days, domain age stops being a primary signal and other factors (content, traffic, reputation) matter more.
Partially. Aged domains carry some SEO value because Google's ranking factors include domain age. But age alone doesn't determine value — content quality, backlink profile, and consistent use over time matter much more. Use this tool to verify the seller's age claim, then cross-reference with Wayback for the content/usage history.
Country-code TLDs often use non-standard WHOIS protocols that this tool's standard port-43 query doesn't handle. For .uk use Nominet's WHOIS service; for .de use DENIC; for .fr use AFNIC. Each registry maintains its own canonical lookup interface.
DNS-level protection services like NextDNS, Cloudflare Gateway, and Cisco Umbrella all support new-domain filtering as a built-in rule. For email, Microsoft Defender, Proofpoint, and Mimecast all offer URL-age filtering. Configure once at the gateway level and the rule applies to your entire organisation without per-user setup.
