What Is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit value typically written as 32 hexadecimal digits in 5 groups, e.g. f47ac10b-58cc-4372-a567-0e02b2c3d479. Version 4 UUIDs are generated using random numbers, giving an astronomically low chance of collision even across distributed systems with no central coordination.
Common Uses
- Primary keys for database records.
- Unique request, session, or trace IDs in logs.
- Generating test fixtures or mock data.
