“The Postal Service has recently learned of a cyber security intrusion into some of our information systems. We began investigating this incident as soon as we learned of it,
and we are cooperating with the investigation, which is ongoing. The investigation is being led by the Federal Bureau of Investigation and joined by other federal and postal investigatory agencies. The intrusion is limited in scope and all operations of the Postal Service are functioning normally. Information potentially compromised in the incident may include personally identifiable information about employees, including names, dates of birth, Social Security numbers,  addresses, beginning and end dates of employment, emergency contact information and  other information.  Postal Service transactional revenue systems in Post Offices as well as on usps.com
where customers pay for services with credit and debit cards have not been affected by  this incident. There is no evidence that any customer credit card information from retail  or online purchases such as Click-N-Ship, the Postal Store, PostalOne!, change of  address or other services was compromised.”
