Frequently asked questions
UUID v4 or v7?
Version 4 is fully random and the most common. Version 7 starts with a timestamp, so IDs sort by creation time, which helps database indexes.
Can two UUIDs ever be the same?
In practice, no. Version 4 has 122 random bits, so a collision is astronomically unlikely.
Is a GUID the same as a UUID?
Yes. GUID is Microsoft’s name for the same 128-bit identifier.
