An RFID chip in an HFC tap contains a unique identifier. The identifier is sent to a user device coupled thereto in response to a request. The user device sends the identifier to a central device,such as a CMTS, along with a traffic stream, such as an emergency 911 call. A location determination storage system coupled to the CMTS receives the emergency call and the tap's unique identifier. The determination system includes a processor and a database that contains a list of tap identifiers and associated physical locations of corresponding taps. The database may be indexed on unique identifier so the physical location of the calling user device can be retrieved based on the unique identifier of the tap that accompanies the emergency message from the user device. Based on the retrieved location of the tap,emergency personnel can be dispatched to the location of the emergency call.
