Frequently Asked Questions

What is a UUID?

A Universally Unique Identifier (UUID) is a 128-bit label used for information in computer systems. The risk of collision is so low it can be ignored for most applications.

Are these UUIDs really unique?

Yes, UUID v4 is based on random numbers. The probability of generating two identical UUIDs is negligible.

Can I use these for database Primary Keys?

Absolutely. UUIDs are widely used as primary keys to avoid collisions in distributed systems.
