(WMBF/CNN) - Target's recent data breach was even bigger than originally believed, and the company will be offering affected customers free credit monitoring services.
The company said Friday that hackers accessed information belonging to 110 million customers, including names, addresses, phone numbers and e-mail addresses, according to the New York Times.
Target said this is separate from the credit and debit card data stolen.
However, the retailer said it is all part of the same breach.
It was discovered as part of the investigation into the theft of card information.
The new number adds the new 70 million users breached to the previous 40 million shoppers who had their credit and debit card information stolen in the weeks following Thanksgiving.
Target still has not explained how hackers accessed the data, saying it remains under investigation.
In a statement released Friday, Target explained the free credit monitoring service will include "a complimentary credit report, daily credit monitoring, identity theft insurance where available, and access to personalized assistance."
"We know this incident has been a confusing and stressful time for our guests, and for that we apologize," said Scott Kennedy, president, Finance and Retail Services, Target. "We hope this offer provides them with additional peace of mind."
The company released details on the service being offered on Monday: one year of ProtectMyID, a service provided by Experian, will be provided to Target customers.
Customers can enroll immediately, and have until April 23, 2014 to request an activation code, and must register before April 30, 2014.
