UUID or ULID

💡 Versions 1, 6, and 7 (and ULIDs) embed a creation time, which is decoded above. Versions 4 are fully random and carry no timestamp. Everything is parsed in your browser.

UUID versions tips

🏷️

The version is encoded in the 13th hex digit. This tool reads it and names the format for you.

🎲

v4 is random (no metadata); v1/v6/v7 are time-based; v3/v5 are name-based hashes.

🔀

It also decodes the variant bits to confirm it's a standard RFC 4122/9562 UUID.

🔒

Parsing is local — paste production identifiers without sending them anywhere.
