How to check domain availability in bulk
- 1Paste up to 10 domain names, one per line, into the box above.
- 2Each one is queried live against its registry through RDAP, or WHOIS for older registries, not a cached list.
- 3Every result comes back together, available or taken, so you can shortlist names in one pass instead of checking each one separately.
Why check domains in bulk instead of one at a time
Checking one name at a time adds up fast when you're brainstorming a brand or naming a new project. This tool runs the same live registry lookup theDomain Availability Checkeruses, just for up to 10 names at once, so a whole shortlist of ideas comes back as one clear list instead of ten separate searches. It's also the fastest way to check a shortlist of available single word domain names you already have in mind, paste them all in and see which ones are still free in one pass.
Built for domain investors screening names before they buy
Domain investors rarely commit to the first name they think of, the real work is comparing several candidates and extensions before registering one. If a batch of ideas comes back mostly taken, generate fresh ones with the Domain Name Generatoror the Short Domain Name Generator, then run the new batch back through this checker.
Found a name? List it for sale on your Expiroo bio page
Once you've registered a domain, Pulse and Business plans include a public bio page at expiroo.com/u/yourname, a shareable link for your social media bio listing the domains you monitor. Mark any of them as for sale with an asking price, and buyers see a live "Monitored by Expiroo" status badge next to it, proof it's a real, working domain, not a parked page.

Frequently asked
How many domains can I check at once?
Up to 10 domains per check on the free tier without an account. Paste one domain per line.
Does this tell me if a domain is registered or who owns it?
This tool only reports available or taken. For ownership and registrar details on a taken domain, use the Whois Lookup tool.
What's the difference between this and the single Domain Availability Checker?
This tool checks up to 10 names at once and reports a simple available or taken for each. The single Domain Availability Checker checks one name at a time but shows full detail on a taken domain, including its registrar and expiration date.
Can I upload a CSV of domains instead of pasting a list?
This tool takes a pasted list, one domain per line, not a file upload. If you already own a portfolio of domains and want their expiration dates from a CSV, use the CSV Portfolio Expiry Checker instead, that's a different check.
What should I do once I find an available domain?
Register it with any registrar before someone else does, since availability can change at any moment. Once it's yours, add it to Expiroo to track its renewal date, or, if you're a domain investor planning to resell it, list it for sale on your Expiroo bio page.
Registered a domain? Don't lose it to a missed renewal.
Add it to Expiroo to track its expiration date and get renewal reminders at 90, 30, 14, 7, 3, and 1 days out, by email, Telegram, WhatsApp, or webhook.
