Hello Roger, 

You can target campaigns to a specific region, which can be a geographical region based on the location targeting. Each targetable location is uniquely identified by the Criterion ID. You will have to use the CampaignCriterionService with the criterion type as Location. In the Location object, you can set the ID of the criteria (for USA, the location ID is 2840) based on the targeting table. To exclude geo targets, you can use NegativeCampaignCriterion. You may refer to this guide and the code snippet for additional guidance. You can also refer to the code sample in Java here. Code samples in other languages are available here.
