What is a UUID?
A Universally Unique Identifier (UUID) is a 128-bit number used to identify information in computer systems. Version 4 UUIDs are specifically generated from random or pseudo-random numbers. The probability of two UUIDs being the same is so astronomically small that it can be considered zero for any real-world application.
