Pay by drop box

Courtesy payment drop boxes are located throughout our Northern Arizona service territory for your convenience.

When paying at a drop box location, submit a check drawn from a U.S. bank or a domestic money order only – no cash, please.

Payment processing

To prevent a delay in the posting of your payment:

  • Allow up to five business days for your drop box payment to post to your account. Use an alternate payment method if you’ve received notice that your service may be disconnected.
  • Verify that your payment is either a U.S. check or a domestic money order. Please do not deposit cash.
  • Print your UES account number on the front of your payment.
  • Enclose the payment with your bill stub in a sealed UES envelope.
  • Insert your payment into one of the drop boxes located at one of the locations listed below.
