# CampaignTargetingCreate.CountryOrRegion

The countries or regions where a new campaign’s ads are eligible to serve.

```
object CampaignTargetingCreate.CountryOrRegion
```

## Discussion

The `countryOrRegion` field uses ISO 3166-1 alpha-2 country codes (for example, `US`, `CA`, `GB`). It’s include-only: the `exclude` array isn’t supported at the campaign level. See [`TargetingDataCreate`](/documentation/Apple-Ads-Platform-API/TargetingDataCreate) for the `include`/`exclude` shape.

Only include markets where the promoted app or brand is available. See [`CampaignTargetingCreate.SupplySource`](/documentation/Apple-Ads-Platform-API/CampaignTargetingCreate/SupplySource-data.dictionary) and [`CampaignTargetingCreate.SupplyPlacement`](/documentation/Apple-Ads-Platform-API/CampaignTargetingCreate/SupplyPlacement-data.dictionary) for the other targeting dimensions.
