Which agency was established to gather identity theft complaints?

The Federal Trade Commission (FTC) is the agency that was specifically established to gather identity theft complaints. It plays a crucial role in consumer protection by collecting and analyzing data related to identity theft and fraud. The FTC also provides resources and guidance to individuals who have experienced identity theft, helping them understand how to report the crime and take steps to recover their identities.

The agency's responsibilities include educating the public about identity theft, maintaining a database of complaints, and working to develop regulations that protect consumers from various types of fraud. As a central repository for identity theft complaints, the FTC collaborates with other federal and state agencies to address issues related to identity theft on a broader scale.

Other agencies mentioned, such as the Department of Justice and the Federal Bureau of Investigation, focus on law enforcement and criminal investigations rather than specifically gathering consumer complaints about identity theft. The Consumer Financial Protection Bureau, while involved in protecting consumers in the financial sector, does not primarily focus on collecting identity theft complaints. The focus of the FTC's work in this area makes it the correct answer.
