JPMorgan Chase Loses Package Containing Customers’ Sensitive Data, Warns Bank Account Info Could Be At Risk

JPMorgan Chase is disclosing a potential data breach to customers.

In a new filing with the Massachusetts state government, Chase says it’s sent a letter to a number of customers warning a package went missing a few weeks ago after leaving one of its branches in the Bay State.

“Our courier reported that a package from our branch at 441 W Broadway in South Boston, MA went missing on its way to our processing facility.

The package contained checks and other paperwork from transactions, including yours, that we processed on or around December 6, 2024. The information included your name, address, and account number.”

While Chase says there are no indications the information contained in the missing package has been used inappropriately so far, the bank is urging its customers to remain vigilant over the next 12 to 24 months.

“Please review your credit reports and account statements for any unauthorized transactions or incidents of suspected identity theft and promptly notify us of activity related to your Chase accounts.”

The largest US lender by total assets also says customers can take additional steps to protect themselves by placing a one-year fraud alert on their credit file with Equifax, Experian or TransUnion.

Customers can also place a security freeze on their credit files with the three credit reporting agencies.

A similar incident occurred in August when a courier bag containing checks and other documents went missing from a JPMorgan Chase branch in San Diego, California, on its way to a processing facility.
