Box 8699, Philadelphia, PA 19101-8699. PECO is Pennsylvania's largest electric and natural-gas utility, serving southeastern Pennsylvania, a subsidiary of Exelon.

What is PECO Energy Company's mailing address?
PECO Energy Company, 2301 Market Street, P.O. Box 8699, Philadelphia, PA 19101-8699. This is PECO Energy Company's publicly listed correspondence address. Confirm it on PECO Energy Company's official contact page before anything time-sensitive — utilities occasionally change offices and PO Boxes.
Can I mail my bill payment to this address?
Not usually. This is a correspondence address for letters, not the payment-processing address most utilities use for mailed cheques. Use the remittance address or PO Box printed on your own bill for payments, and this address for everything else — disputes, service requests, and written notices.
How do I dispute a charge or file a complaint by mail?
Write a clear, dated letter explaining the charge or issue, include your account number and any supporting documents, state what resolution you're asking for, and include your return address. Mailing it creates a dated paper record, which can help if the dispute escalates.
How do I close or transfer my account by mail?
Include your account number, the closing/transfer date, your forwarding address, and a phone number in case PECO Energy Company needs to confirm details. Most utilities also offer this online or by phone, which is often faster if you're on a tight moving deadline — mail is best for a written record or when online/phone options aren't available.
How do I mail PECO Energy Company a letter without a printer?
Write or upload your letter to PostPal with the address prefilled. We print it, add your return address, and mail it for you — no printer, stamps, or post office trip needed.
