Up to 110 million customer accounts may have been compromised by the data security breach at Target Corp.

A glance:
Information from 40 million people initially believed to have been stolen:
names
card numbers
expiration dates
verification or PIN codes
Information from 70 million now said to also have been stolen:
names
mailing addresses
phone numbers
email addresses
Though part of the same breach, it's unclear how much overlap there is between the two sets of stolen data.
