Personally Identifiable Information (PII) is any data that can identify a specific individual, either directly or indirectly. It includes obvious details like a person’s name, email address, phone number, or home address, as well as less obvious data such as IP addresses, device IDs, or purchase history when linked to a person.
In eCommerce platforms like Amazon, PII often includes customer names, shipping details, and order information. Protecting PII is important for privacy, legal compliance (like GDPR or CCPA), and platform rules. Misusing or exposing PII can lead to penalties, account suspension, or legal consequences for businesses.
