Company name to domain: find the website for a list of companies
A company name to domain finder turns a list of company names into website domains. Paste up to 50 names, or 250 after a Google sign-in, and each gets its likely domain with a confidence level and the reason: the official website Wikidata lists for it, or a guessed domain whose home page names the company. Guesses are labelled as guesses.
Sample result
Acme Corporation is at acme.example: its home page names the company. Globex Holdings wasn't found.

How do I find the domains for a list of company names?
- Paste up to 50 company names, one per line (250 when signed in with Google), or upload a CSV with a column headed company or name.
- Press Find domains. Each name is looked up on Wikidata; when that gives no clear answer, guessed domains such as name.com and name.io are checked in DNS and their home pages are read.
- Read each row: the domain, its confidence (high, medium or low) and where the answer came from. Open other candidates when a name is shared by several companies.
- Tick Hide low-confidence guesses, then download the CSV with every domain, reason and candidate.
Example
- You enter
- Two company names pasted one per line:
Acme CorporationandGlobex Holdings. - You get
Acme Corporationcomes backacme.examplewith medium confidence: it isn't on Wikidata, but the guessed domain resolves and its home page is titled Acme Corporation.Globex Holdingscomes back Not found, because no Wikidata item lists a website for it and no guessed domain names it. Download the domains, reasons and candidates as CSV.- Limits
- Up to 50 names a run without an account and 250 when signed in with Google. Guessed domains are name.com, name.io, name.co and the-name.com only, and each home page is requested once.
How do I find a company's domain from its name?
The finder looks the name up on Wikidata, the open knowledge base behind Wikipedia, and reads the item's official website (property P856). When the name matches the item's label or an alias exactly, and the domain resolves in DNS, the answer is high confidence.
When Wikidata has no match, the finder guesses: the name joined up with .com, .io and .co, and with hyphens on .com. A guess only counts when the domain resolves and its home page title or og:site_name contains the company's name. A guess that resolves but doesn't name the company is shown as low confidence, so you can check it yourself.
What do high, medium and low confidence mean?
High: Wikidata lists the domain as the official website of a company with exactly that name and the domain resolves, or several Wikidata items share the name and the best-known one's home page names the company too.
Medium: either several companies share the name (the best known is shown, the others are listed as candidates), or the company isn't on Wikidata and a guessed domain's home page names it. Low: a guess. The domain resolves, or Wikidata's closest match isn't an exact name match, and nothing confirms it. Not found means no credible domain turned up.
Why does a company show no domain?
Most small and local businesses aren't on Wikidata, and many use a domain that can't be guessed from the name, such as a town or a trade added to it. The finder doesn't search Google or scrape other sites, so it can't find those. Try the name as the company writes it on its own site, or a shorter form.
Common words are hard too. A name like Delta or Linear matches many things; the finder prefers items Wikidata describes as companies or organisations, says when the match isn't exact, and lists the rest as candidates.
What should I do with the domains?
A domain is the starting point for outreach, not the end. Build likely addresses for a contact with the bulk email permutator, see who hosts the company's mail with the bulk email provider lookup, then verify the addresses before you send, because a guessed address that bounces costs your domain its reputation.
How is this different from searching each name by hand?
| This finder | Searching by hand | |
|---|---|---|
| Names per run | 50, or 250 signed in | One at a time |
| Where answers come from | Wikidata's official website listing, DNS and the home page | Search results, ads and directories |
| Confidence | High, medium or low with the reason on every row | Your judgement |
| Small local businesses | Often not found | Usually findable |
Who uses this tool, and for what?
- Sales teams
- Turn a list of target accounts into domains, then find and verify the contacts at each one.
- Recruiters
- Get the company domain for each employer on a candidate list before you look up addresses.
- Data teams
- Fill in a missing website column in a CRM export, with the confidence and reason kept beside each value.
- Researchers
- Match a list of organisations to their official websites, citing the Wikidata item for each.
What can’t this tool tell you?
- Only companies on Wikidata, or with a guessable domain whose home page names them, are found. Most small local businesses aren't.
- Names shared by several organisations can return the wrong one; check medium and low rows and the candidates.
- Wikidata is edited by volunteers, so a listed website can be out of date.
- Up to 50 names a run without an account, 250 signed in. Guessed domains that don't answer within a few seconds are skipped.
Common questions
- How do I find a company's website from its name?
- Paste the name into a company name to domain finder like this one. It reads the official website from Wikidata, and when there isn't one it checks guessed domains in DNS and confirms them against the home page title.
- Is there a free Clearbit name-to-domain alternative?
- This free tool does the same job for a list: up to 50 names a run without an account and 250 signed in. It uses Wikidata and DNS rather than a private database, so well-known companies are found and small local ones often aren't.
- Does it search Google?
- No. It uses Wikidata's public API, DNS and one request to each guessed domain's home page. Nothing is scraped from search engines.
- How accurate is it?
- Each row says how sure it is and why. High-confidence rows come from Wikidata's official website listing or a home page that names the company. Low-confidence rows are guesses and should be checked by hand.
- Can it find the domain of a small local business?
- Only when the business uses an obvious domain, such as its name plus .com, and its home page names it. Local businesses are rarely on Wikidata.
- Can I upload a CSV?
- Yes. Upload a CSV with a column headed company, company name, name or organization, and that column is read. A pasted list is read one name per line, so names with commas such as HubSpot, Inc. stay whole.

A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
