What is a UUID?

A UUID (Universally Unique Identifier), also known as a GUID (Globally Unique Identifier), is a 128-bit number used to identify information in computer systems. The main purpose of a UUID is to be unique, meaning that the chance of two generated UUIDs being the same is practically zero.

UUID Versions

  • Version 4 (Random): This is the most common version. It's generated from random or pseudo-random numbers. Due to its randomness, it's highly unlikely to be duplicated.
  • Version 1 (Timestamp-based): This version is generated using a combination of the current timestamp and the MAC address of the generating computer. While still unique, it can reveal information about when and where it was created.
