The domain expiration checker shows when a domain registration ends, when the domain was first registered, which registrar manages it and which name servers it uses. Enter any domain or website URL — we query the official registry of the domain zone via RDAP or WHOIS and show the answer in a clear table.
What You Get
- Expiration date and days left — with an orange warning 30 days before expiry and red when it is urgent or already expired;
- Domain age — the registration date and how many years and months the domain has existed;
- Registrar — the company where the domain is registered and where it has to be renewed;
- Name servers — where the DNS zone is hosted (your hosting provider, Cloudflare, etc.);
- Domain status — for example clientTransferProhibited or redemptionPeriod;
- Availability — if the domain is not registered, you will see that it is free.
If you enter a subdomain such as shop.example.com, the tool automatically checks the registered domain example.com. Country-code zones such as .com.ua, .co.uk or .com.au are supported.
Why the Domain Expiry Date Is Critical
When a domain expires, the website, email and all search rankings disappear at once. After a short grace period the domain can be bought by anyone — often by drop-catchers who resell it or use your traffic for spam. Recovering a lost domain is expensive, and sometimes impossible.
The domain age matters too: an older domain with a clean history usually earns trust faster, so buyers of websites and SEO specialists check it before purchasing a site or a backlink.
RDAP and WHOIS: Where the Data Comes From
RDAP is the modern replacement for WHOIS that returns structured data directly from the domain registry. Where a zone does not support RDAP yet, we use the registry's WHOIS server. Some zones hide part of the data for privacy reasons — in that case the corresponding fields will be empty.
Get a Reminder Before Your Domain Expires
A free reminder is better than a lost website. Register at Seogismo, add your site and enable Website Monitoring: we will email you 30, 14, 7 and 1 day before the domain expires and confirm when it has been renewed. The same dashboard monitors SSL, uptime every 5 minutes, robots.txt and sitemap.xml, and includes a full SEO audit, rank tracking and backlink monitoring. Try it free for 7 days.
FAQ
What happens when a domain expires?
The site and email stop working within hours or days. Most zones then have a grace and redemption period (usually 30–75 days) when only the previous owner can renew the domain, often for an extra fee. After that the domain becomes available to everyone.
How can I find out a domain's age?
Enter the domain above — the “Registration date” and “Domain age” rows show when it was first registered. Note that if a domain was dropped and registered again, the registry shows the date of the latest registration.
Why are some fields empty?
Some registries do not publish the registrar or dates because of privacy rules (GDPR). The expiry date is usually still available.
