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. 

Identity theft is used to commit fraud. A bad actor takes this information and poses as you to steal data or money, or to gain access to privileged information or services.

To protect against identity theft, you will need to guard your personal data and practice good cyber hygiene to keep online information secure and out of the hands of fraudsters.

Identity theft definition

Identity theft is a crime where someone steals the personal data of another person and then uses it to commit fraud, typically for financial gain. The following information can be stolen during identity theft:

  • Name
  • Address
  • Phone number

  • Bank statements and/or account numbers and information
  • Credit card numbers
  • Biometric data

Identity theft can involve a thief literally sifting through discarded documents or trash to obtain personal identity information or stealing off a person directly. It can also involve cybercrime where bad actors steal information or data through scams, malware, hacks, or security breaches. 

Identity theft is usually performed in order to commit identity fraud, which is the use of another individual’s personal information without permission. Identity fraud is when one person claims to be someone else. 

Identity fraud is committed to steal information, get access to restricted resources, or for financial gain. 

Financial losses from identity theft continue to rise. In 2021, they were projected to be close to $725 billion in the United States alone.
