What is a GUID ?

GUID is an acronym which stands for 'Globally Unique Identifier'. A GUID is a 128-bit integer number and usually is used to identify resources in computer systems. The term GUID is used by software developers using Microsoft technolgies, while UUID is used in other places.

How unique is a GUID ?

The algorithm for generating a unique 128-bit integer number (GUID) is good enough so that if for example you generate 1,000,000,000 GUIDs per second for 85 years the probability of a duplicate would be only 50%. Thus the smallest number of generated GUIDs for the probability of finding a duplicate is 103 trillion and the probability is one in a billion.

About GUID Generator

GUID Generator generates a Globally Unique Identifier (GUID) which is a 128-bit number used to identify resources in computer applications. Our tool is free of charge and you can use it as much as you want.

The GUID is an implementation of the UUID (Universally Unique Identifier) standard by Microsoft.
