Frequently Asked Questions

What does a UUID look like?

A standard UUID is a 36-character alphanumeric string separated by hyphens, looking like this: 123e4567-e89b-12d3-a456-426614174000.

Are these UUIDs truly unique?

Version 4 UUIDs have 122 random bits, meaning there are 2^122 possible combinations. The probability of generating a duplicate is practically zero.

What is the difference between UUID v1 and v4?

Version 1 is based on the computer's MAC address and the current time, whereas Version 4 is generated using completely random numbers.

Can I generate UUIDs without hyphens?

Currently, the tool outputs standard hyphenated UUIDs. You can easily remove them in your code using a string replace function if needed.
