Domain Age & Registration Date Lookup
Check the exact registration age in years and months, creation timestamp, expiry countdown, and registrar details for any domain name.
Understanding Domain Registration Age & RDAP Records
What This Tool Actually Checks
This tool queries the authoritative RDAP (Registration Data Access Protocol) endpoint for the domain you enter and parses the structured JSON response for its registration, expiration, and last-updated event timestamps. From the registration date, it computes the exact age in years, months, and days by measuring elapsed time against a 365.25-day average year and 30.4375-day average month (both standard astronomical averages that correctly account for leap years).
It also surfaces the sponsoring ICANN-accredited registrar name and the domain's current status codes (such as clientTransferProhibited), pulled directly from the registrar entity record embedded in the RDAP response.
How to Use It
- Enter a fully-qualified domain name (e.g.
example.com) without a protocol prefix. - Click Check Domain Age. The tool queries
rdap.org, which routes to the correct authoritative registry for the domain's TLD. - Read the headline age figure (years and months), then check the detailed breakdown grid for exact days, expiry countdown, and last-updated date.
- Review the registrar name and domain status codes at the bottom to confirm who currently sponsors the registration and whether transfer locks are active.
RDAP vs Legacy WHOIS
RDAP is the IETF-standardized successor to the original port-43 WHOIS protocol, which returned unstructured, registry-specific plain text that was difficult to parse reliably and had no built-in access control. RDAP responses are structured JSON served over HTTPS, with a consistent schema for events (registration, expiration, last changed), entities (registrar, registrant, technical contact), nameservers, and DNSSEC status across virtually every gTLD and most ccTLDs.
Since GDPR and ICANN's Temporary Specification took effect, personal registrant contact details are redacted by default in both protocols, but RDAP's structured event timestamps remain fully public because they are considered operational rather than personal data. That is why this tool can reliably compute exact domain age even though it cannot show you who owns the domain — for full registrar and nameserver detail, see our WHOIS Lookup Tool.
Worked Example
Suppose a domain shows the following RDAP registration event: 2016-03-14T00:00:00Z, and today's date is August 11, 2026:
- Elapsed time: approximately 3,803 days since registration
- Age calculation: 3,803 ÷ 365.25 =
10 years, with the remainder (≈ 138 days) divided by 30.4375 giving4 months - Reported result: "10 Years, 4 Months" — a domain old enough to have accumulated over a decade of crawl history, backlinks, and brand recognition.
If the expiration event shows 2027-03-14T00:00:00Z, the tool separately reports roughly 215 days until expiry — a routine renewal window, not an urgent warning on its own.
Practical Use Cases
- Vetting acquisition targets: Buyers evaluating an established website or business check domain age as part of due diligence, since older domains typically carry more accumulated search authority than a freshly registered one.
- Backlink and guest post screening: SEO teams check the age of domains offering link placements — a network of sites all registered within the same week is a common red flag for a private blog network (PBN).
- Fraud and phishing triage: Support and trust & safety teams cross-reference domain age when investigating a suspicious link reported by a user, since a large share of phishing domains are registered within 30–90 days of the attack.
- Expiry monitoring: Agencies managing client portfolios periodically check days-until-expiry across domains to catch lapses in a client's own registrar billing before they cause an outage.
Common Mistakes & Limitations
- Confusing domain age with hosting/site age: A domain can be 15 years old while the currently deployed website was only launched last month after an ownership change — domain age says nothing about content freshness.
- Not a direct Google ranking factor: Google has repeatedly stated domain age itself is not used as a ranking signal; any correlation comes from older domains having had more time to accumulate genuine backlinks and content, not the age number itself.
- RDAP coverage varies by TLD: A small number of newer or regional TLDs have incomplete RDAP support, which can cause a query to fail even for a validly registered domain.
- Registrar transfers reset "updated," not "created": Moving a domain to a new registrar changes its last-updated timestamp but never the original creation date, so age calculations remain accurate through ownership or registrar changes.
Frequently Asked Questions
Why does domain age matter for SEO and search engine trust?
While domain age itself is not a direct ranking factor, older established domains have typically accumulated historical backlinks, crawl history, and brand authority, making new content rank faster than on brand-new freshly registered domains.
What is RDAP and how does it differ from legacy WHOIS?
Registration Data Access Protocol (RDAP) is the standardized successor to legacy port-43 WHOIS. It returns structured JSON data over secure HTTPS, providing standardized timestamps and registrar metadata.
How can domain age help detect phishing and scam websites?
A large percentage of malicious phishing, fraud, and spoofed eCommerce websites are registered within the last 30 to 90 days. A domain with 10+ years of continuous registration is a strong signal of legitimacy.
Does this tool sanitize domain inputs against SSRF?
Yes. All domain queries strictly reject localhost, private IP addresses (10.x, 172.16-31.x, 192.168.x), and cloud metadata endpoints.
Why does the reported age sometimes differ from what a registrar dashboard shows?
Age is calculated from the RDAP "registration" event timestamp to the current moment, using a 365.25-day year and 30.4375-day month average to account for leap years. A registrar dashboard may instead show the date of the domain's most recent renewal or transfer, which is a different reference point than the original creation date.
Can a domain's registration date be falsified or backdated?
No. The creation timestamp is set once at the registry level (e.g. Verisign for .com, PIR for .org) at first registration and cannot be edited by the registrant or registrar afterward. This is precisely what makes domain age a comparatively reliable trust signal versus self-reported "About Us" claims.
What does "days until expiry" actually tell me, and should I worry if it's low?
It is a countdown to the domain's current expiration date, based on the registrar's auto-renewal and grace period settings. A low number is not automatically alarming — most registrars auto-renew before expiry — but it is worth confirming your registrar account has a valid payment method on file and auto-renew enabled, since a lapsed domain can be picked up by a third party.
Is domain age alone a reliable way to detect a scam website?
It is one useful signal among several, not a standalone verdict. A domain registered 90 days ago is not automatically malicious — legitimate new businesses register new domains too — and a domain registered 10 years ago can still be compromised or resold to bad actors. Combine this check with a WHOIS lookup, blacklist check, and manual review of site content before drawing conclusions.
