UUID Generator

The UUID Generator creates random version-4 UUIDs (also called GUIDs) for free — one at a time or in bulk — ready to copy into your database, code or config.

What is a UUID?

A UUID is a 128-bit identifier that is practically unique, used to label records, sessions, files and API objects without a central authority. Version-4 UUIDs are randomly generated, making collisions extraordinarily unlikely.

How to use the UUID Generator

1. Choose how many UUIDs you need.
2. Click Generate.
3. Copy the UUIDs into your project.
