JPMorgan Chase & Co has been hit with a proposed class action lawsuit accusing it of printing Social Security numbers on the outsides of form letters mailed to customers to tell them about the bank's efforts to protect their private information.
Filed on Thursday in federal court in Chicago, the lawsuit accused the largest bank in the United States of violating federal and state laws and subjecting its customers to increased risk of identity theft.
A JPMorgan spokeswoman declined comment.
The allegations are another embarrassment for the financial company amid a rash of civil and criminal probes, ranging from the massive "London Whale" trading scandal to possible bribery in China.
On Thursday, it disclosed $1 billion in payouts to settle four civil regulatory probes.
The new lawsuit was filed on behalf of Alexander Furman, a Buffalo Grove, Illinois resident, who said JPMorgan twice mailed him preprinted forms with his name, address and Social Security number on the outsides, and failed to follow up on his complaints.
