Domain Age Checker

See exactly how old a domain is, straight from its registry

Uses RDAP, the modern structured registry-lookup protocol — real registration data, not an estimate.

What Is a Domain Age Checker?

A domain age checker looks up when a domain was first registered and works out exactly how long it's been active — pulled directly from the domain's own registry, not guessed from indirect signals.

How to Check a Domain's Age

1

Enter a domain.

2

Press "Check Age."

3

See its exact age, registration date, expiration, and registrar.

How This Actually Works: RDAP, Not Guesswork

This queries RDAP (Registration Data Access Protocol), the standardized, JSON-based successor to WHOIS. It's the same registry data WHOIS used to expose, but structured and consistent instead of free-text formatting that varies registrar by registrar.

Does Domain Age Matter for SEO?

It's a small, disputed factor at best — there's no solid evidence that an older domain directly ranks higher purely for being older. Where it's actually useful is as a quick trust signal: a domain registered decades ago with a consistent history reads differently than one registered last week, especially when evaluating an unfamiliar site.

When You'd Use This

🔍

Vetting a website

Get a quick trust signal before buying from or trusting an unfamiliar site.

🤝

Due diligence

Check how established a company's domain actually is before a deal.

📊

Competitor research

See how long a competitor's site has actually been around.

Will This Work for Any Domain?

Most common TLDs — .com, .net, .org, .io, and many country-code domains — support RDAP and will return a result. A handful of older or smaller registries haven't adopted RDAP yet and won't have data here.

Limitations

  • Depends on the domain's registry supporting RDAP — not universal yet
  • Shows registration data, not hosting history or ownership changes
  • Domain age is a minor SEO signal, not something worth chasing on its own

Benefits of Using This Tool

  • Real registry data via RDAP, not an estimate
  • Registration, expiration, and last-updated dates in one place
  • Free, no sign-up, nothing stored

Frequently Asked Questions

How does this check a domain's age?

It queries RDAP (Registration Data Access Protocol), the modern structured replacement for WHOIS, and reads the domain's actual registration date straight from its registry — not an estimate.

Why does domain age matter for SEO?

Older domains are often associated with more established sites, though domain age itself is a small and disputed ranking factor at best. It's more useful as a quick trust signal when evaluating a site than as something to optimize for.

Will this work for every domain?

Most common TLDs (.com, .net, .org, .io, and many country codes) support RDAP and will work. A handful of older or smaller registries don't publish RDAP data yet, and won't return a result here.

Is this the same as a WHOIS lookup?

Similar data, better source. RDAP is the structured, standardized successor to WHOIS — same underlying registry data, returned as clean JSON instead of registrar-specific free-text formatting that's inconsistent to parse.

Do you store the domains I look up?

No. Each lookup is a live request to the domain's registry for that one search and isn't stored.
