If anyone arrives at your home or business saying they are from DTE, please ask to see a badge with photo ID. If the person refuses to show their badge, do not allow them inside. If you want to verify a worker’s identity or confirm that a vehicle is an authorized company vehicle, please immediately call DTE at 800-477-4747. If the person becomes agitated or acts in a strange manner, insisting that you let them inside, call 911.
