A LITTLE CONTEXT

What is a UUID?

A universally unique identifier (UUID) is a 36-character value, including hyphens, used to identify records, objects, and test data. It helps different systems create IDs independently.

Which UUID version does this generate?

This tool creates random UUID v4 values using your browser’s built-in cryptographic random generator. The results use lowercase letters and the standard hyphenated format.

Can two UUIDs be the same?

A correctly generated random UUID has an extremely low chance of matching another. This tool checks for duplicates within each batch, but no random generator can promise that IDs will never repeat across all users and time.

Are my generated UUIDs saved?

No. Generation happens in your browser. This website does not upload or store your results. Refreshing the page, switching languages, or generating a new batch clears the previous list.

Do I need an account?

No account or payment is needed. Choose a quantity, generate your UUIDs, and copy the results. UUIDs are identifiers; do not use them as passwords or authentication credentials.
