How to use the UUID Generator

  1. Choose version 4 or 7 and how many you need (up to 1,000).
  2. Optionally switch to uppercase or remove the hyphens.
  3. Select Generate, then copy or download the list.

About this tool

A UUID is a 128-bit identifier that is practically unique without needing a central registry. Version 4 is entirely random. Version 7 starts with a timestamp, so values created later sort after earlier ones, which suits database keys.

Good to know

  • Random bits come from your browser’s secure random generator.
  • Version 7 UUIDs created within the same millisecond are not guaranteed to be in order.
  • A UUID is an identifier, not a secret. Don’t use it as a password or access token.
