Type in any domain name to see when it was registered, how old it is, when it expires and which registrar holds it. The answer comes straight from the registry’s live record, so it’s what the registry has on file right now.
What the checker shows
Domain age is counted from the registration date in the registry’s record. The expiry date tells you how far ahead the current owner has paid. The registrar is the company the name is registered through. Registries publish all of this through RDAP, the system that replaced old-style WHOIS, and the checker reads it directly.
Why domain age matters
If you’re buying a domain, an old registration date is a good sign. A name registered in 1998 has been renewed year after year by someone who thought it was worth keeping. That counts for something when you’re weighing a price.
For SEO it matters less than people think. Google has said that a domain’s age on its own isn’t a ranking factor. What an older domain often has is what built up over those years, like links, mentions and a track record. Age hints at that history. The history is what counts.
When the date looks wrong
When a domain expires and someone registers it again, the registry treats it as a brand-new domain and the clock starts over. So a name that was first registered in 2005 can show up here as two years old if it dropped in between. The checker only sees the current record. To find out whether the name had a life before that, look it up in the Wayback Machine at web.archive.org.
Some country-code extensions don’t publish their registration data this way, and names nobody has registered have no record at all. In both cases you’ll get a “no record found” message.
