Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. When generated according to the standard methods, UUIDs are, for practical purposes, unique. Their uniqueness does not depend on a central registration authority or coordination between the parties generating them, unlike most other numbering schemes.
What version of UUID does this online tool generate?
This tool generates Version 4 (v4) UUIDs, which are created using random or pseudo-random numbers. This is the most common type of UUID used in software development.
Is this UUID generator free to use?
Yes, this online UUID generator is completely free for developers and anyone who needs a unique identifier. You can generate and copy as many UUIDs as you need.
