# Is valid UUID

> Checks if the value is a valid UUID.

Checks whether the incoming value is a valid UUID, the long unique identifier written as five groups of hexadecimal characters separated by dashes, such as `f47ac10b-58cc-4372-a567-0e02b2c3d479`. Use this to confirm an identifier field holds a properly shaped UUID before you use it as a key or pass it to another system, or to route records with a missing or malformed identifier down a different path. By default any valid UUID format is accepted; set a Version to require a specific kind of UUID.

This documentation describes: [Schema](/schemas/condition/format-uuid)

## Fields

<FormField property="version" label="Version">
  The kind of UUID you want to require. UUIDs come in several flavours that differ in how they are generated, and the kind is encoded inside the identifier itself. Choose **Any valid format** to accept any well-formed UUID, **NIL** to accept only the special all-zeros UUID, or one of **V1**, **V2**, **V3**, **V4**, or **V5** to accept only that specific kind. Most integrations use **Any valid format** unless the system you are working with mandates a particular version.
</FormField>

## Sample data

The condition was run against an identifier field with no version set, so any valid UUID format is accepted.

| Incoming value                         | Result         |
| -------------------------------------- | -------------- |
| `f47ac10b-58cc-4372-a567-0e02b2c3d479` | Matches        |
| `12345`                                | Does not match |
