About UUIDs

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

UUID v4 (Random)

Generated using random or pseudo-random numbers. Most commonly used. Extremely low probability of collision. Format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

UUID v5 (Name-based)

Generated using SHA-1 hash of a namespace and name. Same input always produces the same UUID. Useful for deterministic generation.

Common Use Cases
