A little about UUIDs

What is a UUID?

A UUID is a universally unique identifier: a 36-character string, including hyphens, used to distinguish records, objects, or test data. It helps give an item an identifier without needing a central numbering system.

Which version does this tool generate?

This tool generates random UUID v4 values using your browser’s built-in random UUID function. Results use lowercase letters and the standard hyphenated format, ready to paste into your project.

Can two UUIDs be the same?

Duplicates are extremely unlikely with correctly generated UUID v4 values, but absolute uniqueness is not guaranteed. This tool checks each batch and replaces any duplicate within that batch.

Are my results saved?

No. UUIDs are generated in your browser and are never uploaded or saved by this tool. Refreshing, closing the page, or switching languages clears them. Copy any results you want to keep before leaving.
