NBCRightNow.com -- The state's Department of Social and Health Services' Economic Service Administration said private information of possibly 7,000 households may be in the wrong hands after a coding error caused ESA letters to be mailed to clients' previous addresses.
The ESA discovered the error in October and they said they are worried that some of the letters that went to the wrong households may contain private health information.
They also said some letters may include social security numbers, employment or earnings information, and what public assistance services the client is receiving.
All letters were sent in envelopes marked "return service requested", but the DSHS doesn't know how many letters were returned from wrong addresses.
The department is still trying to find out what caused the error; they will notify clients whose credit or identity may be at risk.
