What is UUID v4 (RFC 4122)?
UUID (Universally Unique Identifier) Version 4 is a 128-bit label formatted as 32 hexadecimal characters across 5 groups (8-4-4-4-12). It uses 122 cryptographically strong pseudo-random bits, ensuring virtually zero collision chance across distributed databases.
UUID v4 Collision Probability
UUID v4 has 2^122 (approx. 5.3 × 10^36) possible values. Generating 1 billion UUIDs per second for 100 consecutive years yields only a ~50% chance of a single collision.
