About

UUID Version 7 includes a Unix epoch timestamp in milliseconds, making it time-ordered and sortable. It combines the benefits of time-based ordering (like v1/v6) with a more modern timestamp format. Version 7 UUIDs are excellent for use as database primary keys where you want chronological ordering without exposing MAC addresses. The format includes 48 bits of Unix timestamp, 12 bits of random data, and 62 bits of additional random data, providing both time-ordering and strong uniqueness guarantees.

Use Cases

  • •Database primary keys with chronological ordering
  • •Time-series databases and logging systems
  • •Distributed systems requiring sortable IDs
  • •Event sourcing and audit trails
  • •Modern applications needing time-ordered UUIDs
  • •Systems where MAC address exposure is a concern
