The names and account numbers of 58,522 California residents may have been compromised, and 18,086 additional customers in the state may have other information stolen, not including their names, according to the Los Angeles Times and other reports.

Data may include account number, the card expiration date, the date the card became effective and the four-digit code printed on the front of the card, according to a company statement.
