WHOIS Domain Lookup – Registrar, Age and Expiry Date

Enter a domain to see its registrar, age, expiry date, status and name servers, straight from the registry.

About WHOIS Lookup

A WHOIS lookup answers the everyday questions about a domain: when your own domain expires, which registrar holds a name you'd like to buy, how old a competitor's site is, or whether a domain is locked before a transfer. Enter a domain or paste a full web address. Subdomains are reduced to the part you register, so blog.example.co.uk is looked up as example.co.uk.

We ask the registry over RDAP, the modern JSON version of WHOIS, using IANA's list of servers, and fall back to classic port-43 WHOIS for extensions without RDAP, such as .cn, .io and .de. You get the registrar, registration date and age, expiry date and days left, last update, each status code in plain words, name servers that open a DNS Lookup when clicked, DNSSEC, the abuse contact and the raw record. Domains that expire within 30 days, are on hold or are being deleted are flagged. Details hidden for privacy stay hidden, and a name nobody holds links to the Domain Availability Checker.

How to use WHOIS Lookup

  1. 1
    Enter the domain

    Type a domain such as example.com, or paste a web address and the WHOIS lookup keeps just the domain.

  2. 2
    Click Look up

    We ask the registry's RDAP server, or its WHOIS server when the extension has no RDAP.

  3. 3
    Read the details

    Check the expiry date, days left, status codes and name servers, and open the raw record if you need every line.

  4. 4
    Save or follow up

    Download the result as JSON, or click a name server to look up its DNS records.

FAQ

WHOIS Lookup: questions and answers

How do I find out when a domain expires?
Enter it in the WHOIS lookup. Expires shows the date and Time left counts the days, and a domain with less than 30 days left gets a warning. Your HTTPS certificate expires separately, and the SSL Certificate Checker counts its days left.
Why can't I see the domain owner's name?
Most registrars hide personal details for privacy, and many registries no longer publish them at all. We show what the registry returns, and an organization name appears only when it's public.
Does the WHOIS lookup work for .cn and other country domains?
Yes. Extensions with RDAP are read that way, and those without it, such as .cn, .io and .de, are asked over classic WHOIS on port 43. Some registries publish fewer details than others.
What does clientTransferProhibited mean?
It's the registrar's transfer lock, and it's a good sign. Nobody can move the domain to another registrar until you unlock it. Every status code in the result is explained.
Is the WHOIS lookup free, and is my search saved?
It's free, needs no sign-up and doesn't use your daily tasks, with an hourly allowance per visitor to prevent abuse. The lookup runs when you click and the result isn't stored.
