Microsoft Advertising Editor makes it easy to manage location targets in bulk, using either the multiple changes tool in the Locations tab or an import file. Either way, you’ll need to use the location codes for the location targets that you’re trying to add.

Or if you were doing a file import using the Microsoft Advertising file format, the value from the Location ID column in the file should be assigned to the Target column in your import file.
Note: The ID column is the ID of your location target in Microsoft Advertising. If you want to update existing location targets, include the ID, otherwise, it should be blank if it's a new location target.
