FAQ

What is a UUID?

UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information without requiring a central authority. It is typically represented as a string of hexadecimal characters divided by hyphens. UUIDs are widely used in databases, APIs, and distributed systems where unique identifiers must be generated independently.
