I think there's 4 BC's.
BC 820 covers Carefree, Cave Creek, Rio Verde Foothills, and Fountain Hills.
BC 830 covers the West Valley.
BC 840 covers the San Tan Valley.
BC 850 covers the East Mesa area.
I've heard 82x units (Carefree, Cave Creek and/or Rio Verde Foothills, but not Fountain Hills) sent to the West Valley to assist or cover for 833 & 837. I've not heard the other way around.
