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). Mobile lookups spend phone tokens — an allowance set by your plan, separate from your regular token balance — at 1 phone token per returned result.

Numbers are not screened against Do Not Call registries. MoltSets does not currently return DNC status, and a returned number carries no indication of whether it is registered. last_validated_at tells you the number was active and in service on that date, nothing more. Scrubbing against the applicable DNC registries, and complying with the calling and messaging rules that apply to you, remains your responsibility.

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
