What information does the domain age checker show?

The checker displays the registered domain's age in years, months and days, registration and expiry dates, registrar, DNSSEC status, nameservers and the date the record last changed. All data comes from the public registry record.

Can I use the domain checker without an account?

Yes. The tool at /domain-age-checker is free and open to all visitors. You can search any bare domain, subdomain or full web address.

Why might a domain's age appear to start fresh?

If a domain registration lapses and is then registered again, the age counter begins from the new registration date, not the original one.

Understanding domain registration data on Seen Here First

How to read domain registration records from the public registry, what they reveal and where the information originates.

The free domain checker

Visit /domain-age-checker to search any domain at no cost, without logging in. Enter a bare domain, a subdomain or a full web address; the tool looks up the registered domain itself. You'll see the public record from the registry: domain age (in years, months and days), the date first registered, expiry date, most recent change, the registrar, DNSSEC signing status and nameservers. The page timestamps when the record was last checked.

Domain info on a listing

Each product listing displays a Domain info box among its metrics, showing the founder's registered domain using the same registry data. This includes age, registration and expiry dates, registrar name and DNSSEC status, plus a link to view the full record on the checker. The site refreshes this information roughly every week.

Where the data lives

All records come from RDAP, the registry's public successor to WHOIS. Not all registries publish this data; several country-code registries withhold it. When no data exists, the page will say so. Should a registry temporarily fail to respond, wait a few minutes and search again.

What age tells you

Domain age counts from the current registration only. If a domain lapses and is registered afresh, the counter begins from that new registration date. Registration age does not influence how listings appear on this site.
