Citibank may have printed your Social Security number on outside of envelope

As you may have heard, Citibank messed up. Big time. It accidentally sent out more than 600,000 mailings to customers with their Social Security numbers printed on the outside of the envelopes.

One of WalletPop's editors was one of those 600,000, and she received a letter from Citibank that read in part (entire contents at American Banking News):

"We are writing to inform you that due to a processing error the nine digits in your Social Security number, along with a string of other numbers and letters all resembling a mail routing number, were printed on the lower edge of an envelope containing a year-end tax statement that we mailed to you recently.
