Frequently Asked Questions
How does the domain age checker work?
We query RDAP (Registration Data Access Protocol) and WHOIS databases to find the exact registration date, expiry date, and registrar information for any domain.
Why does domain age matter?
Domain age is a trust signal for search engines (SEO), email deliverability, and cold email outreach. Older domains tend to have better reputation scores and higher deliverability rates.
What if the registration date is not available?
Some domain registries restrict access to registration data for privacy reasons. In these cases, we show "Not available" — this is a registry limitation, not a tool issue.
What registrars can you detect?
We detect all major registrars including GoDaddy, Namecheap, Cloudflare, Google Domains, Porkbun, Hover, Name.com, and many more. If the registrar data is not exposed via RDAP/WHOIS, we show "Not available".
