This happened at my previous house, except with an additional twist: the street name was changed to an identical streetname, less than a mile away, but within a different city.

Adding to the confusion, my address was duplicated on that other street with a commercial brokerage which often gets sued. How do I know about these lawsuits? — because several process servers showed up (over about eight years living there) to sue the other address. They never believed my factual explanation: the numbers repeat on the same road, so closely ("yeah, ok buddy").
