Frequently asked questions

What's the difference between v1 and v4 UUIDs?

v4 UUIDs are fully random and the standard choice for most uses. v1 UUIDs are derived from a timestamp, which can leak when they were created — most modern systems default to v4 unless they specifically need time-ordering.

Can two generated UUIDs ever collide?

In practice, no. A v4 UUID has 122 random bits, making the odds of a collision low enough to be considered effectively zero for any real-world use.

Can I generate a lot of UUIDs at once?

Yes — use the bulk option to generate a batch and copy them all together.
