Ads in your Google Ads campaigns are eligible to display in any location around the world. If you want your ads to appear only in specific locations, you can select the city, province, or region by specifying geo codes or postal codes and adjusting bids for the area. You can also use the geo codes and postal codes to exclude locations by city, province, region, metro code or postal code.
You can use geo codes to specify an entire country, specific regions within a country (such as a province or state), city, or US metro area. You can also target specific postal codes in the US, UK, Germany, or India.
