Free to start · up to 3 domains monitored free

Checking domains one at a time doesn't scale. DomainExpiryCheck lets you import a whole portfolio at once and returns each domain's expiration date, registrar, domain status and transfer-lock state using live RDAP and WHOIS data. It's the fastest way to run a bulk domain expiration check across hundreds of names - then keep monitoring them so nothing lapses.

Up to 500 domains per import

Paste a newline- or comma-separated list, or upload a CSV. We look up every domain in parallel and show the results in one dashboard.

Real WHOIS & RDAP data

Each domain is resolved against the authoritative registry via RDAP, with WHOIS fallback, for accurate expiry dates across thousands of TLDs.

Monitor after you import

Imported domains are re-checked daily. Get email and webhook alerts at 30, 14, 7, 3 and 1 days before each one expires - no more spreadsheets.

How the bulk domain checker works

1 Create a free account and open the bulk import page.

3 Review expiry dates and status, then let automatic monitoring watch them for you.

Bulk domain checker - FAQ

How many domains can I check at once?

Up to 500 domains per import. You can run multiple imports to cover larger portfolios, and every imported domain is then monitored automatically.

Is the bulk WHOIS lookup free?

Yes - you can run bulk checks for free. The free plan monitors up to 3 domains continuously; paid plans raise the monitoring limit for larger portfolios.

What formats can I upload?

Paste a plain list (one domain per line or comma-separated) or upload a CSV. We clean and de-duplicate the list automatically before running the lookups.
