Wells Fargo & Co. blames a printing error for mailing numerous Florida and South Carolina customers statement details from other people.
The San Francisco company has 487,000 customers in the state. It did not say how many were affected by the breach, which stemmed from a malfunctioning printer in Charlotte, The Post and Courier of Charleston, S.C., reported Friday.
The error led to the names, account numbers and, in some cases, Social Security numbers of affected customers being added to the statements of strangers, the article said. A bank employee told The Post and Courier that the breach affected 30,000 people, but bank spokesman Josh Dunn told the paper he could not confirm that figure.
Wells Fargo is offering a year of identity theft protection to the affected customers, Dunn told the paper.
