What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. Unlike sequential IDs, UUIDs are globally unique, making them ideal for distributed systems, database primary keys, and transaction IDs. Our UUID Generator creates random v4 UUIDs that are safe and secure for any application.
