What does the code on the Verizon outdoor box mean?

[Jenn W]

There is a Verizon box at the back edge of my property with the letter/numbers "C 25 6" on it, along with a picture of a phone. Can anyone tell me what this code means? We are being told thay we do not have the right type of wires run for DSL or cable internet, even though the people that live at "C 25 1" have access. I hate Verizon.

The box at the edge of your property is probably an underground junction box for wires. DSL is mostly limited by your distance from the central switching office, not the underground junction box.
