Understanding UUIDs

What is a UUID?

UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. Version 4 UUIDs are randomly generated and have extremely low probability of collision (1 in 5.3 x 10³⁶).

Format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

Where x is any hexadecimal digit and y is one of 8, 9, A, or B

Advantages:

  • • No central authority needed
  • • Generated independently
  • • Virtually collision-free
  • • Works in distributed systems

Common Applications:

  • • Database record IDs
  • • API authentication tokens
  • • Microservice correlation IDs
  • • File system object names
