UUID Decoder

Back to Web Tools

A Universally Unique Identifier, commonly referred to as a UUID or GUID, is a method of generating a moderately sized, unique identification value. Commonly used in registration systems of various types, these identifiers actually have multiple standards and can even contain data, despite appearing random.
This tool supports all variants of Versions 0 through 5 of the UUID standard, as well as "Version 6" by Bradley Peabody. For details on these versions, see the ITEF RFC Whitepaper or the Wikipedia article.
Note: UUID numbers are not easily traced back to a source - if you're trying to find, for example, a bluetooth device by a UUID, you probably won't have any luck. In such cases, check if the unknown device only appears in certain areas - often, smart hardware such as lights, TVs, and other appliances will have a bluetooth connection available to initiate pairing, if they're having network connection problems, or if there's been a recent update to their firmware.

Enter your UUID and press the button to decode.

Notes:
•  When decoding version 3 or version 5 UUIDs, two unknown nibbles will be marked with question marks in the Hash data. The first nibble is always completely unknown, but only the first two bits of the second nibble are unknown. The second two bits of the second unknown nibble will be listed above as "Second Nibble".
•  When decoding version 2 UUIDs, the Generated date value may be off by up to seven minutes.
