Generate GUID

About Our GUID Generator Website

A Globally Unique Identifier (GUID) is an algorithmically generated 128-bit binary number identifier. GUIDs are primarily used in networks or systems with multiple nodes and computers. Ideally, no computer or computer cluster will generate two identical GUIDs. The total number of possible GUIDs is 2^128 (3.4×10^38), making the probability of generating two identical GUIDs extremely small, but not zero. Therefore, algorithms used to generate GUIDs typically incorporate non-random parameters (such as time) to ensure such duplication does not occur.

• Option to choose uppercase letters and whether to include hyphens
• Generate multiple GUIDs at once, with no duplicates - each one is randomly generated
• Easily copy and download generated GUIDs to local txt file
