UUID Inspector

Inspect a UUID’s version, variant and embedded timestamp where its format includes one.

Inspect a UUID

UUID Generator

Enter a valid UUID to inspect it.

What the inspector reads

It recognizes the UUID version and variant. Versions 1 and 6 contain a Gregorian-epoch timestamp; version 7 contains a Unix timestamp in milliseconds; version 4 is random and has no embedded creation time.

UUID versions at a glance

  • v1: time-based legacy format.
  • v4: random identifier.
  • v6: reordered time-based UUID for improved sortability.
  • v7: Unix-time-ordered UUID with random data.

The inspector does not validate ownership, authenticity or uniqueness. It only reads the structure of the value supplied.
