Marriott said the database includes identifying information for some 327 million customers, including names, phone numbers, email addresses, passport numbers, date of birth, and more. Encrypted credit card numbers were included for some customers, though Marriott doesn’t know whether the numbers were decrypted by hackers.

Marriott is sending emails to affected customers and established a call center to answer questions about the incident.
