Paste the string into a browser-based UUID validator and it tells you whether the value is a valid UUID and, if so, which version and variant it is. The check runs on your device with no account needed.
A UUID is 32 hexadecimal digits arranged in five groups separated by hyphens, and certain positions encode its version and variant. A string that is the wrong length, has stray characters, or has invalid version bits is not a real UUID even if it looks close. A validator parses the string against these rules and reports whether it passes.
Beyond a simple pass or fail, a good validator tells you which version the UUID is, from 1 through 8, and which variant, which is useful when debugging why one system rejects an id another accepts. The check happens in your browser, so the value you paste is never uploaded. It is free and needs no sign-up.
It must be 32 hex digits in five hyphen-separated groups with valid version and variant bits.
Yes. A valid UUID is reported with its version number and variant.
No. The check runs in your browser, so nothing is sent to a server.
