FAQ

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. UUID v4 uses random numbers, making collisions extremely unlikely.

Is UUID v4 truly unique?

While not mathematically guaranteed, the probability of generating two identical UUID v4 values is approximately 1 in 2^122, making collisions practically impossible.
