Online UUID generator
About UUID generator
UUID Generator is a simple and free online tool that quickly generates random UUID values. There is no warranty that the generated UUIDs are unique, though the chance is very high to be unique.
What is UUID?
A universally unique identifier (UUID) is a 128-bit number used to identify information in computer systems. The term globally unique identifier (GUID) is also used, typically in software created by Microsoft.
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. While the probability that a UUID will be duplicated is not zero, it is close enough to zero to be negligible.
Common usage of UUID
- Unique keys in database tables
- Operating System internals
