How do I check if a phone number has a Facebook account?
Put the numbers in a plain .txt file, one per line with the country code, for example +14155551234, and upload it to TalismanLeads. The result marks each one registered or not registered on Facebook, at $1.00 per 10,000 numbers. The owner of the number is not contacted, and files under 2,000 entries are billed as 2,000.
