What to know first

In this scam, criminals combine real stolen details, such as your Social Security or ID number, with fake information to create a synthetic identity used to open accounts and credit that can affect you.

Identity theft uses stolen personal data, from phishing, data breaches, or mail theft, to open accounts, claim benefits, or take over existing accounts in your name. It can go undetected for months, which is why early monitoring and credit freezes matter.

The core pattern to watch for is clear: Accounts, credit, or records appearing under your ID number that you did not create. Check your credit report and consider a credit freeze or fraud alert.
