What is a UUID?

A UUID (Universally Unique Identifier) is a standardized identifier used in software development to uniquely identify objects or records. Because UUIDs are generated using random numbers or timestamps, the chance of duplication is extremely small.

Common Uses of UUIDs

UUIDs are commonly used in databases, distributed systems, web applications, APIs, authentication systems, and cloud platforms. They allow developers to create unique identifiers without needing a central authority or database counter.
