The company said today that hackers accessed information belonging to 110 million customers, including names, addresses, phone numbers, and e-mail addresses.
Target says this is separate from the credit and debit card data stolen.
However, the retailer says it is all part of the same breach.
It was discovered as part of the investigation into the theft of card information.
You'll remember, Target had previously said 40 million shoppers had their credit and debit card information stolen in the weeks following Thanksgiving.
