Note: Google Ads location targeting doesn’t determine geographic borders.
Like dining etiquette and power outlets, location target types vary by country. Google Ads allows you to target different types of locations, including postal codes, cities, regions and more. But, keep in mind that some target types aren't available in all countries.
You can also choose to show your ads to people in places of interest, such as airports or universities.
Refer to the list of target types and relevant resources in the Google Ads Help Center.
