List Metro Codes in Region

Why List Metro Codes In a Region?

When you are reviewing regions within a country, it can be helpful and useful to also retrieve specific metro codes within that region so you can geo-target exclusive metro regions. For example, if you would like to target audiences within the United States in the state of California, you may wish to further narrow down the geographical areas where you want ad to be served. With the Kevel API, you can use the MetroCodes query parameter within a specific Region to return a list of all metro codes within a region.



The List Metro Codes in Region endpoint is only available for United States regions.
