Google has made an update to the AdWords location extensions. It now shows up to 3 business locations in mobile search ads. When a business has several locations nearby, users will be able to see up to 3 locations in an ad.
The extensions can display street address as well as distance from the user's current location. Users can click to call or even get directions for each of the 3 locations.
Location extensions are automatically enabled to show up in the ads as a single location or in group of 2 or 3. You can learn more about the location extensions at the Help Center.Google Mobile Search Ads to Feature Multiple Business Locations!,
