# documentRegion

A locale region that’s relevant to the scanned string.

```
var documentRegion: Locale.Region?
```

## Discussion

Set `documentRegion` to the region relevant to the scanned string, if any.

> Important:
> Only set this value if you know it with a high degree of confidence; otherwise, set to `nil`.
