About UUIDs

Universally Unique Identifiers (UUIDs) are 128-bit numbers used to uniquely identify information in computer systems.

UUIDs are standardized by the Open Software Foundation (OSF) and documented in RFC 4122 and RFC 9562. They are widely used in distributed systems, databases and software development.
