Maybe. Depends on if the subscriber was honest when they signed up. For example, Verizon asks only for a Zip to match on prepaid accounts. The number would have to be associated with a person in our database, who has established the phone number for themselves, and used it in applying for jobs, magazine subscriptions, or utilities if it's not listed in their name with the carrier. So, yes, but it's a 50/50 chance if it is known to be prepaid.
