What Does UID Mean
Definition
UID stands for Unique Identifier. It is a code, number, or string that is used to uniquely identify a person, device, or object in a system. Each UID is distinct and cannot be duplicated within the same system.
In simple terms, a UID is like a digital fingerprint that helps systems recognize and differentiate entities.

In technology, UIDs are used in databases, apps, websites, and network systems to manage and verify information without confusion.
