UUID Generator

Generate random version-4 UUIDs, one at a time or in bulk.

How to use the UUID Generator

Choose how many UUIDs you need and press generate, then copy the list. Version 4 UUIDs are random, so they suit database keys, test data and unique identifiers.

FAQ

What is a UUID?

A UUID is a 128-bit identifier written as 32 hex characters, designed to be unique without a central authority.

Can two UUIDs collide?

With version 4 the chance is so small that it is ignored in practice.
