Domain Age Checker

What is the Domain Age Checker?

The Domain Age Checker finds the registered domain behind a URL or subdomain, discovers its authoritative Registration Data Access Protocol service through the IANA bootstrap directory, and calculates its age from the registry's public registration event.

The report also organizes creation, update and expiry dates, registrar details, registry status codes, nameservers, DNSSEC state, and the exact RDAP source. Registration age is not the same as the date a website was launched, first indexed, or first archived.

How to check a domain's registration age

1. Enter a domain, subdomain, full website URL, or the domain part of an email address.
2. Choose Check Domain. International domain names are converted safely to their DNS-compatible form.
3. Review the exact age breakdown and the creation, update, and expiry timeline.
4. Open Registration for registrar and registry identifiers, or DNS & Security for nameservers, status codes, and DNSSEC.
5. Copy the plain-language report, export the same result as JSON, or open the authoritative RDAP response source.

Why use this RDAP domain age lookup?

• Uses IANA's official bootstrap directory to discover the registry's authoritative RDAP service.
• Normalizes URLs, email domains, subdomains, trailing dots, and internationalized domain names.
• Calculates calendar years, months, days, and total registered days from a published registration event.
• Explains expiry urgency and common registry status codes instead of showing an unexplained raw list.
• Keeps the visible report, copied summary, JSON export, and source link synchronized from one lookup result.
