An SSN tracker is a service provided by companies to protect you from identity theft. If you are signed up for the SSN tracker service and there are threats to your identity, you will be notified and may even be eligible for stolen funds reimbursement. Information monitored includes publication of your information on the dark web, changes in your credit, crimes committed in your name, data breaches involving companies you have purchased from in the past, home title monitoring, bank/investment accounts opened with your SSN, etc. You may also receive additional services protecting your identity when you’re online, such as a VPN account and other privacy monitors.
