UUID Version 1 Generator

Generate single or multiple time-based UUIDs (Version 1)

Single UUID

Bulk UUID Generation

About UUID Version 1:

  • Based on timestamp and MAC address
  • Guaranteed uniqueness across space and time
  • Contains the time of generation
  • MAC address ensures uniqueness across different machines
  • Suitable for distributed systems where timestamp ordering matters

📝 Note:

UUID v1 uses the current timestamp and your computer's MAC address to generate unique identifiers. While this ensures uniqueness, it may expose timestamp and hardware information. For privacy-sensitive applications, consider using UUID v4 (random) instead.
