How to find business phone numbers
Describe your target market and title
Add your target market or industry and the title you want to reach. Sculptor sources matching companies and waterfalls through Clay's provider network to find a verified phone number for each.
Sculptor assembles companies and finds phone numbers
Sculptor builds a matched company list filtered by your target market or industry, then runs a waterfall through Clay's provider network to surface a verified phone number for the title you specified. Only matched rows return a phone number.
Your table: company name and verified phone number
The finished table has company name and, for matched rows, a verified phone number for the title you specified. Push to Smartlead, Instantly, or your sequencer to launch outreach.
Why Clay for finding business phone numbers
B2B company sourcing with ICP filters
Source target companies by industry, headcount, funding stage, tech stack, and location from Clay's B2B company database. Google Maps pulls also return a direct business phone number with every row, no extra step needed.
Multi-provider waterfall for phone coverage
Get verified business and direct-dial numbers for matched rows. Clay waterfalls through multiple providers in sequence and only charges credits when one returns a hit, pushing coverage well beyond what any single provider delivers.
Built-in number validation before outreach
Every phone number runs through validation via ClearoutPhone or Trestle before it reaches your team, flagging disconnected lines, landline types, and inactive numbers so reps dial only verified, active contacts.
Claygent confirms role before dialing
Claygent browses each company's LinkedIn and site to confirm the target title is still in role, then pushes verified rows to Salesforce, HubSpot, or your sequencer ready for outreach.
When one provider doesn’t have it, Clay automatically checks the next one. It really helps our inbound and outbound motions because we can leverage the best source of data. I’ve never seen a tool that was so easy to do this process.
Frequently asked questions
How does Sculptor find business phone numbers?
Sculptor queries Google Maps for your target industry and location, returning each matching business with its name, address, and listed phone number. It then routes every row through Clay's waterfall enrichment, which checks up to 10 phone data providers to locate the owner's direct number when the public listing isn't enough.
How accurate are the business phone numbers Clay returns?
Clay tested 9,806 numbers across 10 B2B phone data providers and found that 23% scored as high-propensity (P1) numbers, meaning they connect with the intended contact at least 25% of the time. Waterfall enrichment stacks multiple sources per row, so overall coverage climbs well above any single provider. The SMB-specific waterfall targets owners who rarely appear in standard B2B databases.
Can I find business phone numbers in bulk?
Yes. Paste a list of industries and locations, upload a CSV, or pipe rows from an existing Clay table to run hundreds of lookups at once. Sculptor populates every row with company name and owner phone, then you can push the finished list straight to HubSpot, Salesforce, or export as a CSV for your cold-calling team.
Is it legal to collect and call business phone numbers?
In the U.S., the TCPA allows live, manually dialed B2B cold calls to business lines without prior consent, but you must scrub against the National Do Not Call Registry every 31 days and call only between 8 AM and 9 PM local time. Automated or prerecorded calls to mobile numbers require prior express written consent. In the EU, GDPR permits B2B outreach under a legitimate interest basis, though some member states require explicit consent for personal mobile numbers.
Rules vary by state and country, so always check the regulations for your jurisdiction before dialing.
