There was one time when the missionaries told me that they could not find a member's home. They were using the map location (which was wrong), rather than using the street address.
In another case, a sister's street address was on South 26th Ave Cir, and another home with the same number was on South 26th Ave, about 200 feet away. So of course, the mapping location again pointed to the wrong house. She was very familiar with her packages being delivered to the other house.
For those folks who live on an acreage, you would need to decide whether to set the mapping location on the house, or on the entry of their very long driveway or access road.
