What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit label used for information in computer systems. The probability of a collision (generating the same UUID twice) is so infinitesimally small that for all practical purposes, every UUID generated is unique.
Version 4 UUIDs
This tool generates Version 4 UUIDs, which are based on random numbers. This is the most common version used in modern applications.
Format Example
