About UUID v4

A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems.

UUID v4 uses random or pseudo-random numbers. The chance of collision is extremely low:

  • Total possible UUIDs: 2122 ≈ 5.3 × 1036
  • Collision probability with 1 billion UUIDs: ~0.00000000000000000001%

Common Uses:

  • Database primary keys
  • Session identifiers
  • Unique file names
  • API request tracking
  • Distributed systems coordination
