UUID v6 Generator

Generate UUID v6 values and compare this time-ordered format with UUID v1 and UUID v7.

What is UUID v6?

UUID v6 is a time-ordered version related to UUID v1. It rearranges timestamp bits so values sort more naturally by creation time.

Like UUID v1, UUID v6 needs careful handling of node and sequence fields. This browser generator uses random node bytes.

UUID v6 vs UUID v7

UUID v7 is usually the better modern choice for time-ordered IDs because it uses Unix epoch milliseconds plus random data.

Use UUID v6 mainly when you need compatibility with systems that specifically understand v6.

FAQ

Is UUID v6 time ordered?+

Yes. UUID v6 is designed so generated values sort more naturally by timestamp than UUID v1.

Should I use UUID v6 or UUID v7?+

Prefer UUID v7 for most modern time-ordered use cases unless your system specifically requires v6.

Does this UUID v6 generator expose a MAC address?+

No. It uses a random node identifier in the browser.
