There are three specific types of identity theft aside from the broad term. Tax-related identity theft is when a criminal uses someone else's SSN to get a tax refund or a job. Victim of this type of theft must contact the IRS. Child identity theft is when a criminal uses a child’s SSN to apply for governmental benefits, open bank accounts, or apply for a loan. Medical identity theft is when a criminal uses someone else's name or health insurance to see a doctor, get a prescription or other various medical needs.
