A UUID (Universally Unique Identifier) is a 128-bit identifier used to uniquely identify information in computer systems.

What is the difference between UUID v1 and v4?

UUID v1 is timestamp-based and includes the current timestamp and a node identifier (often the MAC address). UUID v4 is random and doesn't rely on system time or MAC addresses.

How many UUIDs can I generate at once?

You can generate up to 50 UUIDs in one batch. Select the quantity from the dropdown menu before generating.

Can I validate existing UUIDs with this tool?

Yes, simply enter the UUID in the validation field, and the tool will check if it conforms to the UUID standard.

Are the generated UUIDs guaranteed to be unique?

UUIDs are designed to be globally unique, but in extremely rare cases, collisions might occur, especially with v4 (random) UUIDs. For most practical purposes, they are considered unique.
