Generate an identifier, copy it, or use Re-generate for another value.
The UUID and GUID Generator displays an identifier you can copy for application data or tests. Select Re-generate when you need another value.
A UUID is a 128-bit identifier commonly written as 32 hexadecimal characters in hyphen-separated groups of 8-4-4-4-12. For example: f47ac10b-58cc-4372-a567-0e02b2c3d479. GUID is another name used for this identifier format.
UUID v4 is associated with random identifier generation, but the format alone does not establish how a value was generated or guarantee that it will never collide. Keep database uniqueness checks where your application requires them.
Identifiers can help label test records, requests, files, or distributed-system events. An identifier is not an authorization check. Do not rely on knowing or hiding one to control access to a resource.
The page does not show bulk generation, case options, brace options, or file downloads. If you need a .txt or .csv file, copy the values into your own document. Do not assume the output is suitable as a session secret or another security token without verifying the generation method and your application's requirements.
