Identifier Generator: Choosing a Format

How to use this tool

Select an identifier style and generate values for local fixtures or interface previews. Use UUID v4 when your test specifically expects the standard UUID v4 layout.

Limits and safe use

The tool also includes compact and numeric identifier styles that are not UUIDs. Random identifiers are not a substitute for your application’s database uniqueness guarantees or security tokens.
