What Is Identity Theft? Definition & Examples

Identity theft is when someone steals personal or financial information about someone else and uses it to commit fraud.

Identity theft is one of the top concerns for consumers. In 2020, the Federal Trade Commission (FTC) received more reports of identity theft than any other form of complaint, with these reports making up nearly a third of all complaints with close to 1.5 million reports about identity theft.

Identity theft can occur when criminals steal your personal information, including your name, birthday, address, phone number, social security number, and/or financial information. This can be done in either the physical or digital world — wherever personal data is stored.
