What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. While the probability that a UUID will be duplicated is not zero, it is so close to zero as to be negligible. This version generates Version 4 UUIDs, which are constructed from random or pseudo-random numbers.
