Reverse lookup

Find person or company by phone (single)

Given a phone number, find the associated LinkedIn profile or company.

Mobile and home phones typically resolve to people, while front desk or business phones may resolve to companies.

Only charges 1 credit when a result is found. No charge for invalid numbers or misses.

If you have additional identifiers (name, company, email) beyond just the phone number, use the Kitchen Sink endpoint instead for better match quality.
