Common Issues & Solutions

Can't Find Account Number on Bill

Look for alternative labels: "Customer Number," "Service Account," "Contract Account," or "Account ID."

Don't Confuse With Meter Number

Your meter number is different from your account number. The meter number is usually on your physical electric meter.

New Customer / Just Moved

If you just moved or are a new customer, you'll need your first bill before you can switch suppliers. This usually arrives 30-45 days after service starts.

Digital Bills

Check your email for digital bills, or search for emails from your utility company. The account number will be in the same location as paper bills.
