How to find mobile and direct-dial phone numbers
Describe your target contacts and companies
Paste your target company list or describe the market you want to reach. Sculptor waterfalls through 150+ providers to find a verified mobile or direct-dial number for each contact.
Sculptor chains providers to find verified numbers
Sculptor searches Clay's people database for matching contacts, then waterfalls through 150+ providers in sequence, querying the next only when the previous returns no match. Only matched rows consume credits.
Verified name and phone number per matched row
The finished table has contact name and verified mobile or direct-dial number where the waterfall found a match. Push to your dialer, Outreach, or Salesloft to connect with prospects directly.
Why Clay for finding mobile / direct-dial phone
2-3x more coverage than any solo provider
Get verified mobile and direct-dial numbers for far more contacts. Clay's waterfall enrichment chains 150+ providers in sequence, querying the next only when the previous returns no match, so coverage climbs from roughly 30% to 80% or higher.
Built-in validation flags dead lines before dialing
Every matched number runs through Trestle validation, which scores phone activity, confirms line type, and flags disconnected or landline numbers, so only live, dialable mobile and direct-dial numbers reach your reps.
Credits charged only when a match is found
You pay nothing for providers that come up empty. Clay runs each provider in the waterfall for free until one returns a hit, stretching your enrichment budget further than any flat-access phone data subscription.
Push verified numbers to Outreach or Salesloft instantly
Send matched rows with verified mobile and direct-dial numbers directly to Outreach, Salesloft, or HubSpot in one click. Scheduling auto-refreshes the table daily, weekly, or monthly so your dialer lists stay current.
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 mobile and direct-dial numbers?
Sculptor runs your target company list or industry through a waterfall of up to 10 mobile data providers in sequence. If the first source misses, the next one fires, and you only pay when a number is found. The waterfall auto-adjusts provider order by region, with Forager leading on accuracy globally and ContactOut filling APAC gaps, so one workflow covers multi-region lists.
How accurate are the mobile numbers Clay returns?
Coverage jumps from roughly 30% with a single provider to 80% or higher using Clay's waterfall across 10 sources. Numbers can also pass through TitanX scoring, where P1-rated numbers carry a verified connection rate of 25% or above. That means your team dials the highest-quality numbers first and skips dead lines.
Can I find mobile numbers for a whole list at once?
Yes. Paste your list, upload a CSV, or pipe contacts from an existing Clay table. Sculptor processes every row through the same waterfall in bulk. Once numbers are verified, push them directly to your CRM or dialer, or export the full table as a CSV for your outbound team.
Is it legal to cold call B2B mobile numbers I find?
In the US, the TCPA allows live B2B cold calls to manually dialed numbers but requires you to scrub lists against the National Do Not Call Registry at least every 31 days. Autodialers to wireless numbers need prior express consent, and violations can cost $500 to $1,500 per call. In the EU, GDPR permits B2B calling under a documented legitimate interest basis, though several member states require consent for calls to personal mobiles.
State and country rules vary widely, so always check the regulations for your jurisdiction before dialing.
