"Save Contact" Search

On a burner phone that you only use for investigations and skip tracing, "Save" the subject's number into your phone contacts, then give every social media platform permission to "Find your Contacts". If the number was used to create an account, it will be located.


Create an account as an Employer. With an employer account, it gives you access to a full database of resumes. You cannot search names, but you can filter High Schools, Cities, Jobs, and other keywords.
