Get Carrier-Verified Mobile Phones

LinkedIn to Mobile Phone

The LinkedIn to Mobile Phone API looks up the carrier-verified mobile phone number for a LinkedIn profile, along with the date it was last verified.

Only mobile numbers are returned, no landlines or VoIP numbers, so every result is a real device. It supports single lookups (linkedin_url) and batch lookups of up to 100 profiles at once (linkedin_urls). External tokens are required for mobile phone lookups, at a cost of 10 tokens per returned result.

Use this endpoint to:

Power SMS outreach and cold calling
Enrich sales sequences with direct-dial mobile numbers
Batch-append verified phone numbers to a contact list

Fair Use Policy: This API is subject to our Fair Use Policy for Enrichment.

External Tokens: MoltSets resolves most contact data — emails, phone numbers, et al. — from its own database. For some requests, the data you’re looking for isn’t in that database, and MoltSets will make a call to a third-party data source to try to find it. Those calls cost external tokens.
