Cities, ZIP Codes and DMAs | In version 139 of our Atomx User Interface we added City, ZIP and DMA targeting and reporting. City and ZIP targeting is available worldwide. DMA is only available in the United States. For better explanation: DMA means ‘Designated Market Area’ regions, that are geographic areas in the U.S. Further information you will find here -> http://www.nielsen.com/intl-campaigns/us/dma-maps.html
