If you’re annoyed by nuisance calls, take charge! Customer Originate Trace enables you to initiate a trace on your last incoming call. Traced information will be provided to law enforcement officials if you choose to prosecute.

To use Customer Originate Trace:

  1. When you get a nuisance call, press and quickly release the switchhook. Listen for a special dial tone. If you’ve already hung up, just lift the handset again and listen for a normal dial tone.

  2. Press *57 (On a rotary phone, dial 1157). After you press *57, you’ll hear an announcement telling you whether or not the call can be traced. Just follow the voice instructions to dial an additional code, and the call will be traced.

  3. Listen for a confirmation announcement that the last call has been traced. Hang up.

  4. The number you traced will be recorded at Norvado.


  • This feature will not work with calls originating from an area or long distance carrier not providing Caller Identification service, toll free numbers, some 700 and 900 numbers, international calls and some cellular calls.

  • Customer Originate Trace must be used immediately after you hang up on the call you want traced. If you get another call, or hear a Call Waiting tone first, you will trace the wrong call.

  • If the call is traceable, call your local law enforcement agency and report the information to have a case opened.

  • After a case number has been assigned, call Norvado at 715.798.3000 and they will follow the appropriate steps to have the call traced.

  • The proper authorities will contact you in regards to any information collected.

If you have additional questions please contact our service department at 855.330.1143.
