A UUID is a 16-octet (128-bit) number. In its canonical form, a UUID is represented by 32 hexadecimal digits, displayed in five groups separated by hyphens e.g.

5a0e8422-e29b-41d4-a716-416155440000

UUID is standardised by the Open Software Foundation (OSF) as part of the Distributed Computing Environment (DCE).
