UUID 39956017-4BE7-4436-85C9-42DC6885E751

A universally unique identifier (UUID) 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. While the probability that a UUID will be duplicated is not zero, it is close enough to zero to be negligible.
