Frequently asked questions
Can two UUIDs ever be the same?
In theory yes, in practice no. You would have to generate billions per second for many years to have a realistic chance of a duplicate.
What is the difference between UUID and GUID?
They are the same thing. GUID is the name Microsoft uses; UUID is the standard name.
When should I use UUID v7 instead of v4?
Version 7 starts with a timestamp, so new IDs sort in creation order. That helps database indexes, while v4 is fully random and reveals nothing.
Can I use uppercase or remove the hyphens?
UUIDs are case insensitive, so both are valid. If a system expects a specific form, adjust the case and hyphens after copying.
Is UUID generator free?
Yes. UUID generator on Toolipedia is free to use, with no sign-up and no watermark.
