The unofficial tandem list of the former Sprint network (now defunct).
This is a list of the former Sprint long distance tandems that were used throughout the United States as of 2000. This list was provided by the late telephone researcher Mark Cuccia (1961-2014). This list is incomplete and nowhere near correct. The entire Sprint long distance network was disconnected circa 2017.
