Yup, that’s possible. On the settings page there’s a google map where you can set a marker to the default location. It’s also possible to set the zoom and map type.

Postcodes aren’t required. Anything the user writes in the location field gets passed to Google and the closest location gets returned. So the more details, the more accurate the result will be. You could only write “Uzbekistan” and the location of that user will be right in the middle of it.
