Free Bulk Domain Checker lets you check domain registration dates, last updated dates, and expiry dates for multiple domains on one page. Paste your domain list, choose Check dates, and review a separate three-date card for each domain.

Free Bulk Domain Checker is a bulk domain lookup tool for reviewing registration and expiry dates across a domain list. Use it to check the recorded expiry dates of domains you manage, compare registration dates in a research shortlist, or collect domain dates for your own notes. Each result keeps the domain name next to its dates, so you can move through the list without opening a separate page for every domain.
As a domain registration date checker and domain expiry date checker, it focuses on three recorded dates. It does not determine whether a domain is available to buy or show a history of domain owners. A last updated date is a record update date; it does not tell you when the website's content last changed.
Enter a group of domains in the multiline input. The checker recognizes plain hostnames and website URLs, removes a leading www., and keeps each distinct domain once. The counter beside the input reports how many valid domains are ready. Invalid text is skipped before the lookup begins, and repeated domains do not create repeated result cards.
After you choose Check dates, the results appear progressively in Domain dates. Each domain has its own card, with a checking message until the result is ready. A completed card shows Registered, Last updated, and Expires. Dates use a readable month, day, and year format, such as Sep 10, 2026. If a date is unavailable, that field reads No date reported. A failed lookup displays Dates unavailable or Could not load domain dates in the affected card while the remaining results continue.
- Paste one domain per line into Add domains.
- Check the ready count above the field, next to Add domains.
- Choose Check dates.
- Read the three date fields in each card under Domain dates.
- Choose Clear list to remove the current input and results.
The placeholder demonstrates the intended format with example.com, openai.com, and github.com on separate lines. Replace these examples with the domains you want to check. If the ready count is lower than expected, look for duplicate entries or invalid text; the counter reports both when present. If no valid domains remain, Check dates asks you to add at least one valid domain.
You can use Clear list while a check is in progress as well as after it finishes. This clears the input and all current result cards, returning the page to its starting state for a new list.
Separate entries with new lines, spaces, commas, or semicolons. Plain domains and http:// or https:// URLs are accepted. For example, https://example.com/about becomes example.com: the domain date lookup concerns the domain, not the individual page. Uppercase names become lowercase, and a trailing dot or leading www. is removed. Consequently, EXAMPLE.COM, www.example.com, and example.com produce one card.
Subdomains such as blog.example.com remain separate entries from example.com; accepting an entry does not guarantee that dates are available for it. Invalid hostnames, single words without a domain suffix, and unsupported URL forms are skipped.
Each domain card has a small sequence number and three labeled date fields:
- Registered is the registration date supplied for the domain.
- Last updated is the supplied domain record update date.
- Expires is the recorded expiry date, when available.
Read an expiry date as the recorded date at the time of your check, not a guarantee that the domain will become available on that day. Missing dates do not establish that a domain is unregistered. A card can contain some reported dates and some No date reported fields.
Cards stay in the order of your accepted domain list. On smaller screens, the date fields stack vertically. The status line below the input reports progress during a bulk domain check, then shows how many records are ready and how many are unavailable. Use the individual cards to see which dates were actually reported.
The checker runs in your web browser and needs an internet connection to look up domain dates. It displays dates in English without a time of day. The page does not offer automatic renewal reminders or ongoing monitoring; open the checker and run a new check when you want to review a domain list again.

The page asks only for domain names needed for the lookup. It does not require an account, name, email address, password, or profile. The Clear list control removes the visible input and results from the page. No personal form fields are included in the interface.
