What is a version 4 UUID?

A version 4 UUID is a universally unique identifier generated from random numbers. The version 4 UUIDs produced here use a cryptographically secure random number generator, so they’re a safe default for database keys, request IDs, and anywhere you need a collision-resistant identifier.

UUID versions explained

Version 7 — timestamp ordered

A Unix-millisecond timestamp followed by random bits. Sortable by creation time, which makes v7 excellent as a database primary key.

Version 1 — time-based

Built from a timestamp, a clock sequence and a node. For privacy we use a random node (not your MAC address), per RFC 9562.

Nil / Empty UUID

All zeros: 00000000-0000-0000-0000-000000000000. A placeholder meaning “no UUID”.

GUID format

A GUID is the same 128-bit value, conventionally shown UPPERCASE in braces. Pick the Braces format above to produce {…}.
