Frequently Asked Questions
What UUID versions are supported?
This validator detects standard UUID versions v1 through v5 when format and variant bits are valid.
Can I validate multiple UUIDs at once?
Yes. Paste one UUID per line and the tool validates each line independently.
Is this the same as checking uniqueness?
No. The tool validates format and version bits, but it cannot guarantee global uniqueness.
