Frequently Asked Questions

What version of UUID is generated?

Version 4 (random). These are the most commonly used UUIDs, generated from cryptographically secure random numbers.

Are the UUIDs guaranteed to be unique?

Practically yes. The probability of a v4 UUID collision is astronomically low — about 1 in 2^122. You would need to generate 1 billion UUIDs per second for 85 years to have a 50% chance of a collision.
