A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. Our generator creates Version 4 UUIDs, which are generated using random numbers, making them ideal for use as database keys, transaction IDs, or any scenario where a unique identifier is required.
This tool leverages the browser's built-in cryptographic functions to ensure a high degree of randomness and uniqueness. Simply click the button to generate a new UUID, ready to be copied and used in your applications.

Frequently Asked Questions
What is the difference between a UUID and a GUID?
Functionally, UUID and GUID (Globally Unique Identifier) are the same. GUID is Microsoft's implementation of the UUID standard. Version 4 UUIDs are the most common type and are based on random numbers.
Are these UUIDs truly unique?
The probability of a collision (generating the same UUID twice) is astronomically low, making them unique for all practical purposes. The total number of possible v4 UUIDs is 2^122, an incredibly large number.
