Customer service records: The notes, tickets and transcripts support staff created about you: problems you reported, verification details you gave, refunds, account changes and sometimes internal comments.
Dates of birth: Your full birth date, day, month and year, collected at signup for age checks, identity verification, insurance quotes, birthday offers or government services.
Driver's licenses: Your driver's license or licence number, often with the card number, expiry, address, date of birth and photo, and sometimes a scan of the front and back of the card.
Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.

Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
