UUID Generator

About UUID Generator

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.

When generated according to the standard methods, UUIDs are for practical purposes unique, without depending for their uniqueness 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.

Thus, anyone can create a UUID and use it to identify something with near certainty that the identifier does not duplicate one that has already been, or will be, created to identify something else. Information labeled with UUIDs by independent parties can therefore be later combined into a single database, or transmitted on the same channel, with a negligible probability of duplication.

This UUID generator can generate random UUIDs. By default, it generates 10 uppercase UUIDs containing hyphens and braces. You can customize whether to include hyphens, braces, and select uppercase or lowercase. You can generate up to 5000 UUIDs at a time.
