UUID Version Reference
| Version | Typical Use | Notes |
|---|---|---|
| UUIDv7 | Recommended default for new apps, databases, and APIs | Time-ordered and random enough for general use |
| UUIDv6 | Ordered identifiers in systems that previously used UUIDv1 | Reorders timestamp bits for better sort behavior |
| UUIDv4 | General random identifiers and older integrations | No embedded timestamp |
| UUIDv1 | Compatibility with legacy timestamp-based workflows | Includes time-based structure and older semantics |
