Domain age checker
Free domain age checker via RDAP: registration date, age in days/years, and expiration when published.
Domain age is estimated from RDAP registration events when registries publish them. Older domains are not automatically trustworthy, but age is a useful research signal.
How age is calculated
We read RDAP events for registration (and expiration when present), then compute days/years since creation in UTC. Some TLDs redact or omit dates — then age cannot be shown.
Use with other signals
Pair age with nameserver checks, DNS, and IP ownership when researching phishing or brand abuse. Age alone never proves legitimacy.
