CHICAGO (AP) – Personal information of nearly 9,000 Illinois families was sent by the state to the wrong mailing address in November and December last year. State officials said they’re working to ensure the error doesn’t happen again.
The Illinois Department of Central Management Services said Friday that a change of address registry from the USPS was matched with an out-of-date client file by a state employee.
A news release noted the resulting file was loaded into IES, the State’s eligibility system, and incorrectly changed the address for 8,848 [Health and Family Services] and [Illinois Department of Human Services] households.
As a result of the error, in late November and December 2020, notices were mailed to 8,848 households at incorrect addresses. Notices were sent to the right customer name at the wrong customer address.
The notices may have included names, case numbers, names of dependents, birth dates and even confidential medical information. According to the agency, of the 8,848 notices that were mailed, one notice included a complete Social Security number, and five notices included a complete bank account number.
To date, the Departments said they’re unaware of any actual or attempted misuse of personal information as a result of the incident.
