Once you’ve signed into Google Ads, navigate over to Ad Extensions. From the drop-down menu, select Location extensions.
Next, select your Google My Business account and double check your location to see if everything is okay. Once you’re done, click on Finish. Now that you’ve set up your location extension, navigate over to Call extensions. This setting will enable users to access your phone number and call your business.
Target & Bid by Specific Locations

Here, select one or more locations and adjust your bids next to Bid adjustment. For more details on how to do that, here is a support link from Google.
