Frequently Asked Questions

Everything you need to know about Uptrue — no fluff.

What is WHOIS?
WHOIS is a protocol used to query databases that store registered users of Internet resources, including domain names. A WHOIS lookup returns information such as the domain registrar, registration and expiry dates, nameservers, and sometimes contact details (though many registrars now redact personal information under GDPR). This tool uses the modern RDAP (Registration Data Access Protocol) standard to retrieve this data.
Enter the domain name in the tool above and click "WHOIS Lookup". The results will show the registrar (the company where the domain was registered) and any available contact information. Note that under GDPR, personal contact details are often redacted for domains registered in the EU and UK.
Not always. Since GDPR came into effect in 2018, registrars must redact personal contact details for individuals. Business registrations may still show company information. Some TLDs (like .uk) also limit what is publicly available. This tool retrieves whatever is publicly available via RDAP.
Domain status codes indicate the current state of a domain. Common statuses include "clientTransferProhibited" (the domain cannot be transferred away, a normal security measure), "clientUpdateProhibited" (changes are locked), "active" (normal operation), and "pendingDelete" (the domain is scheduled for deletion). Multiple status codes can apply at once.
The expiry date is shown in the Registration Details section of the results. If the domain is expiring within 90 days, the tool will highlight this with a warning. If it has already expired, it will be shown in red. We recommend setting up automated domain expiry monitoring with Uptrue to get notified well in advance.

Never let your domain expire

Uptrue's domain expiry monitoring alerts you via email, Slack, or webhook at 90, 30, and 7 days before expiry. Pair it with WHOIS registrar monitoring to catch unexpected ownership or registrar changes the moment they happen. Set up once and forget about it.
