What is a UUID version 4?

A Universally Unique Identifier (UUID) is a 128-bit label used for database identifiers, primary keys, and unique transaction handles. Version 4 UUIDs are completely randomized, meaning the probability of identifier collisions is virtually zero.

How the UUID Generator Works

This generator conforms to RFC 4122 specifications, utilizing cryptographically random seeds to build 32 hexadecimal values separated by hyphens (8-4-4-4-12 pattern). You can instantly generate unique keys to use in database schema migrations, testing mocks, or API development.
