About UUID Decoder (v1, v7)
The UUID Decoder reads version 1 and version 7 UUIDs and pulls out the data embedded in them. Paste a UUID and the tool shows its version and, for time-based versions, the timestamp it encodes, along with node information for v1.
The decoding happens in your browser, so the identifiers you paste are not sent anywhere. This is useful for finding out when a record was created from its UUID, or for confirming which version a system is generating when ordering by identifier matters.
Frequently asked questions
- What is the difference between UUID v1 and v7?
- Both embed a timestamp, but v1 also includes a node identifier, while v7 uses a time-ordered layout designed to sort well in databases.
- Can every UUID be decoded?
- Only versions that embed data, such as v1 and v7, reveal a timestamp; random versions like v4 contain no decodable information.
- Is the timestamp the creation time?
- It is the time the UUID was generated, which usually matches when the associated record was created.
