Frequently Asked Questions

What is a UUID?

A universally unique identifier (128-bit) used in programming to uniquely tag records or objects, with a near-zero chance of collision even across millions of generated IDs.

Is every generated UUID guaranteed to be 100% unique?

The chance of collision between two UUID v4 values is so small it's considered practically impossible, which is why it's widely used in databases.

Can I generate more than one ID at once?

Yes, you can set any count you want (up to 100 IDs) and get them all at once, ready to copy.
