First Target and then Home Depot and now the United States Postal Service has had a data breach that has hit millions.

As KDVR reported, hackers have recently broke into another service that the majority of this country uses, the U.S. Postal Service.

The USPS confirmed that their computer system was breached and personal data was stolen, including Social Security numbers, for 750,000 employees and retirees.

The breach also compromised the data of 2.9 million Postal Service customers, the official said.

The personal data of the 750,000 employees and retirees included birthdates, addresses and employment codes used in the Postal Service’s payroll systems, the official briefed on the matter said.

The USPS is notifying employees and retirees Monday and will pay for credit monitoring for those affected, the official said.

USPS customers’ data affected includes names, home addresses, phone numbers and emails, the official said.
