How to Pay Your Commonwealth Edison Bill Online and by Mail
Commonwealth Edison bill payment methods and where to send payments
Commonwealth Edison (ComEd) serves northern Illinois and lets you pay your electric bill through their website, by phone, by mail, or in person. The fastest way is online through ComEd's website or their mobile app — you can pay when ready without waiting for mail delivery. If you prefer not to use the internet, you can call their automated phone line, mail a check, or pay at a payment center.
Your bill shows a due date, usually about 20 days after the bill arrives. ComEd does not charge a fee for paying online, by phone, or by mail. If you use a third-party payment service or credit card, that service may charge you a fee — ComEd does not control those charges.
The payment method you choose does not affect your account or your rates. Pick whichever method fits your routine. If you are behind on your bill, ComEd has hardship programs, but those are separate from payment methods and are handled through their customer service line.

Paying online through ComEd's website or app
Go to ComEd.com and log into your account using your username and password. If you do not have an account, you can create one by entering your account number (found on your bill) and your zip code. Once logged in, select "Pay My Bill" or a similar option — the exact wording changes occasionally, but it is always on the main dashboard.
Enter the amount you want to pay. You can pay your full bill, a partial amount, or more than you owe (the extra becomes a credit on your next bill). Choose your payment date — you can pay when ready or schedule a payment for a future date. Enter your bank account or debit card information. ComEd accepts checking accounts, savings accounts, and debit cards. They do not accept credit cards on their website, though some third-party payment processors do.
The ComEd mobile app works the same way. read it from the Apple App Store or Google Play, log in with the same username and password, and follow the same steps. Payments made before 5 p.m. Central Time on a business day usually post to your account the same day.
Paying by phone
Call ComEd's automated payment line at 1-877-426-6331. You will need your account number and a checking account or debit card. The system will ask you to enter your account number using your phone keypad, then guide you through the payment steps. You can pay when ready or schedule a payment for a future date.
If you prefer to speak with a person, you can call ComEd's customer service line at the same number and ask to be transferred to a representative. Wait times vary, especially during business hours. Representatives can also help if you have questions about your bill or need to discuss payment arrangements.
Paying by mail
Write a check or money order payable to Commonwealth Edison. Do not send cash through the mail. Include your account number on the check — write it in the memo line or on the back. Mail your payment to the address printed on your bill. This address is usually a processing center, not a local office.
Mail takes 7 to 10 business days to reach ComEd's processing center. If your bill is due in fewer than 10 days, paying by mail risks a late payment. ComEd considers a payment late if it arrives after the due date shown on your bill, regardless of when you mailed it. If you are cutting it close, use online or phone payment instead.
Keep a copy of your check or a photo of the front and back for your records. If you need proof of payment, you can log into your ComEd account online and view your payment history.
In-person payment at ComEd centers and authorized retailers
ComEd has payment centers in northern Illinois where you can pay in person with cash or a check. Go to ComEd.com, select "Pay My Bill," and look for "Payment Locations" or a similar link. Enter your zip code to find the nearest center. Hours vary by location, so check before you go.
Some grocery stores, pharmacies, and check-cashing services also accept ComEd payments. These are authorized retailers, and ComEd's website lists them by area. Bring your account number and your bill if possible. Payment is usually when ready, though some retailers may charge a small fee — ask before you pay.
Setting up automatic payments
If you want to pay the same amount every month without thinking about it, you can set up automatic payments through ComEd's website. Log in, go to "Billing & Payment," and look for "Autopay" or "Automatic Payment." Choose the amount (your full bill, a fixed amount, or a percentage), the date each month when you want it to be withdrawn, and your bank account or debit card.
Automatic payments come out on the date you choose. If that date falls on a weekend or holiday, ComEd withdraws the payment on the next business day. You can change or cancel automatic payments anytime through your account. If your bill amount changes significantly, you may want to adjust your automatic payment amount to match.
What happens if your payment is late
ComEd adds a late fee to your bill if payment arrives after the due date. The fee amount varies and is shown on your bill. If your bill remains unpaid for 60 days, ComEd may disconnect your service. Before disconnection, ComEd sends notices and offers a chance to pay or set up a payment plan.
If you cannot pay your full bill, contact ComEd's customer service at 1-877-426-6331 and ask about payment arrangements or hardship programs. ComEd offers extended payment plans for customers with financial hardship, and some may be may be able to access for bill information through state or local programs. These options are separate from the payment methods described above.
