What is a UUID?

UUID (or GUID) is an acronym for 'Universally Unique Identifier' (or 'Globally Unique Identifier'). The term GUID is generally used by developers working with Microsoft technologies, while UUID is used everywhere else.

UUID Uniqueness

128-bits is big enough and the generation algorithm is unique enough that if 1,000,000,000 UUIDs per second were generated for 1 year the probability of a duplicate would be only 50%.

UUIDs Usage

UUIDs are used in enterprise software development in C#, Java, and C++ as database keys, component identifiers or just about anywhere else a truly unique identifier is required.
