What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. Version 4 UUIDs are randomly generated and have an extremely low probability of collision, making them ideal for database primary keys, session tokens, and distributed systems.
