About UUID Format
A UUID (Universally Unique Identifier) is a 128-bit identifier standardized by RFC 9562. It is typically represented as 32 hexadecimal digits displayed in five groups separated by hyphens in the format xxxxxxxx-xxxx-Vxxx-xxxx-xxxxxxxxxxxx.
- UUID v4 — Random. All bits except the version (0100) and variant (10xx) are randomly generated. Ideal for most use cases where identifiers need no meaningful ordering.
- UUID v7 — Time-ordered. The first 48 bits encode a Unix timestamp in milliseconds, making values sortable by creation time. Great for database primary keys and time-series data.
