Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. They're commonly used in databases, distributed systems, and APIs.
What version of UUID does this generate?
This tool generates UUID v4, which is based on random numbers. UUID v4 is the most common version for general use.
Are these UUIDs guaranteed to be unique?
While no UUID can be mathematically guaranteed to be unique, the probability of collision with UUID v4 is astronomically low (about 1 in 10³⁶), making them practically unique for all real-world applications.
