FAQ

What is a UUID?

A UUID is a 128-bit label used to uniquely identify data. Written as 32 hex digits: 550e8400-e29b-41d4-a716-446655440000.

UUID v4 vs v1 — which should I use?

Use v4 for most cases — it is random and doesn't leak system info. Use v1 only when you need time-sortable IDs.

Can two UUIDs ever be the same?

Astronomically unlikely. UUID v4 has 2^122 possible values. Generating a collision would take longer than the age of the universe.

Is UUID the same as GUID?

Yes. GUID (Globally Unique Identifier) is Microsoft's name for the same concept. They are interchangeable.
