How to find your
Special Circuit number
If the ID number is not known from your records of services with D&E, it is typically marked on the cover of the Network Interface Device (NID), the cabinet or enclosure for the device associated with the circuit, or on the device itself.
If there is a NID, it is most often a gray plastic box, approximately 8 inches by 10 inches, mounted in your telephone/equipment room, or on the outside of the building, usually near the electric meter.
If there is a device, it is likely mounted in your telephone/equipment room, and it may show lights or LED’s that differ from normal. This device may be an ADTRAN, AFC, or a device from another manufacturer. The circuit ID is usually in the form of 2 numbers/4 letters/6 numbers/2 letters, for example, 13/HCGS/123456/PA.
