# SKANError.Code.adNetworkIdMissing

The ad network identifier in the ad impression doesn’t match the value in the information property list.

```
case adNetworkIdMissing
```

## Discussion

The value you specify for your ad network identifier in your ad impresion must match the value in the `Info.plist`. ``An app that participates in ad campaigns by displaying ads must include the ad network identifiers in its `Info.plist`. For more information, see [Configuring a source app](/documentation/StoreKit/configuring-a-source-app).
