faq

What is UUID v4?

It is a version of UUID generated using purely random numbers, containing 122 random bits.

Can collisions happen?

The probability is astronomically low, making it safe for nearly any scale of application.

Should I keep the hyphens?

While the standard includes them, many developers strip them to save 4 bytes in storage.
