Is this free to use?
Yes. It uses public RDAP registration data, so there are no paid APIs or keys involved.
Check a domain's registration date, age, expiry date, and registrar using free public RDAP registration records.

Domain age itself is not a Google ranking factor - Google has repeatedly stated this directly. The correlation people notice between older domains and better rankings runs through what those domains have accumulated over time (backlinks, content, established history), not the age number itself.
That makes domain age a useful research and diligence signal rather than an SEO ranking signal: checking how long a competitor's domain has existed, verifying a domain's registration history before buying it, or getting quick context during due diligence. This tool queries live RDAP records to answer that research question directly.
This tool looks up a domain's registration record using RDAP (the modern, structured successor to WHOIS) - first resolving which registry endpoint handles the domain's TLD via IANA's public RDAP directory, then querying that registry directly for the actual record. It returns the registration date, calculated age (in years, months, and days), expiry date, registrar, and last-updated date, when the registry provides them.
Provide the public domain you want to inspect.
The tool resolves the correct registry endpoint and runs a live registration lookup.
Review registration date, domain age, expiry, and last update details.
Copy or download the result for audits, sales checks, or SEO research.
Type the public domain you want to check.
The tool resolves the correct registry endpoint for that domain's TLD via IANA's bootstrap directory, then queries it live.
See the registration date, calculated age, expiry date, registrar, last-updated date, and status codes.

Input
Domain: example.comResult
Registration Date (e.g., 1995-08-14), Domain Age (e.g., "30y 11m 8d"), Expiry Date, Registrar name, Last Updated date, and the RDAP server URL that answeredDomain Age is calculated precisely in years, months, and days from the registration date to today - not just a rounded year count.
Confirm how long a domain has actually been registered and when it's due to expire.
Look up how long a competitor's or vendor's domain has existed as one input in broader diligence.
Check the Expiry Date field to see if a domain might become available soon.
Problem
Solution
Google has stated domain age is not a ranking factor - the real correlation runs through what an older domain has accumulated (links, content, history), not the age number.
Problem
Solution
This tool queries RDAP, the structured, modern successor to WHOIS - there's no WHOIS text-protocol lookup or fallback anywhere in it.
Problem
Solution
Some registries simply don't expose a creation date via RDAP - the tool reports "Not available" rather than guessing, and that's expected for some TLDs and registrars.
Problem
Solution
A domain's registration date isn't necessarily when its current website launched - a domain can be re-registered after expiring, carrying an old-looking date with entirely new content.
Problem
Solution
The tool looks up one domain per request - there's no batch mode.
If you need to know when a domain's current content actually launched (not just when it was registered), check a tool like the Wayback Machine alongside this lookup.
An old domain with little real history is not inherently more trustworthy to Google than a new one - look at actual content and links instead.
RDAP status codes (like "active" or "pending delete") can tell you more about a domain's current state than the age alone.
Privacy rules (like GDPR) commonly redact personal registrant contact details in RDAP responses - registration and expiry dates are generally still exposed even when registrant details aren't.
This tool provides research and diligence data, not an SEO trust or ranking score - domain age itself does not affect Google rankings.
If a domain's TLD isn't covered by RDAP or its registry doesn't respond, the lookup fails outright - there's no WHOIS text-protocol fallback.
Not every registry exposes a creation date, expiry date, or registrar name via RDAP - missing fields show as "Not available" rather than an estimate.
A domain can be re-registered after expiring - its RDAP creation date reflects the current registration, not necessarily when its present content first went live.
One domain per request - there's no way to check multiple domains at once.
The tool doesn't show past ownership records or website history - it reports the current live RDAP record only.
Each lookup is a one-time live result - previous domain checks aren't saved between visits.
Both look up domain registration data, but RDAP is the newer, structured protocol this tool actually uses.
| RDAP (what this tool uses) | Traditional WHOIS | |
|---|---|---|
| Data format | Structured JSON, consistent field names across registries | Free-text output that varies by registry, harder to parse reliably |
| Endpoint discovery | A public bootstrap directory (IANA) points to the correct registry server | No standardized discovery - tools often hardcode server lists |
| Status | The modern, ICANN-endorsed successor protocol | Being phased out in favor of RDAP for many TLDs |
Which should you use?
This tool relies entirely on RDAP for accuracy and consistency - domains whose registries haven't adopted RDAP, or that don't expose certain fields through it, will show "Not available" for those fields rather than a WHOIS-sourced guess.
The most common question is whether domain age affects search rankings. It doesn't, directly - Google has stated repeatedly that domain age itself is not a ranking factor. What actually correlates with rankings is what an older domain has accumulated over time: backlinks, content, and history. Use this tool for research and diligence (how old is this domain, when does it expire, who's the registrar), not as an SEO scoring signal. The FAQ below covers missing data, RDAP vs. WHOIS, and what's checked.
Yes. It uses public RDAP registration data, so there are no paid APIs or keys involved.
Most public TLDs should work, but some registries expose limited registration fields or omit creation and expiry events.
That usually means the registry did not return a creation date in its RDAP response, so the tool cannot calculate the age reliably.
