The fastest way to pay ComEd online is through their website or mobile app, both of which let you pay immediately without waiting for a check to arrive in the mail

ComEd offers three main online payment routes: their website at ComEd.com, their mobile app (available on iOS and Android), or by setting up automatic payments from your bank account. You can pay with a debit card, credit card, or bank account transfer. Payments made before 8 p.m. Central Time on a business day typically post the same day; payments after that or on weekends post the next business day.

You'll need your ComEd account number to get your free guide. You can find it on your paper bill, in the top right corner, or in your online account if you've already registered. If you don't have an account yet, you can create one with just your account number and zip code.

Key Takeaways

  • ComEd's website and mobile app both process payments the same day if submitted before 8 p.m. Central Time on a business day.
  • You need your account number (found on your bill) to pay online, but you don't need to create a login first.
  • Automatic payments from your bank account eliminate the need to remember to pay each month and may may have access to you for a small discount.
  • Credit card payments are accepted but may carry a processing fee, while debit cards and bank transfers typically do not.
  • If your payment doesn't post within two business days, contact ComEd directly to confirm it was received.

Paying through ComEd's website

Go to ComEd.com and look for the "Pay My Bill" button, usually on the homepage. You can pay as a guest without logging in — just enter your account number and zip code. The site will show your current balance and due date.

Select your payment method (debit card, credit card, or bank account), enter the amount you want to pay, and confirm. ComEd will show you the processing fee upfront if one applies — credit card payments typically carry a fee of 2 to 3 percent, while debit and bank transfers do not. You'll receive a confirmation number immediately and an email receipt shortly after.

Using the ComEd mobile app

Download the ComEd app from the Apple App Store or Google Play Store. Open it and tap "Pay My Bill." You can enter your account number and zip code as a guest, or log in if you have an existing account. The app works the same way as the website — you'll see your balance, choose a payment method, and get an instant confirmation.

The app also lets you set up automatic payments directly from this screen, which is useful if you want to avoid logging in each month. You can choose to pay the full balance or a fixed amount on a date you select.

Setting up automatic payments to save time

Automatic payments pull money from your bank account on a date you choose each month. You can set them up through the website, the app, or by calling ComEd at 1-877-426-6331. Most customers choose their bill due date or a few days after to avoid overdrafts.

ComEd sometimes offers a small discount (usually $0.25 to $0.50 per month) for customers on automatic bank account payments. Ask about this when you set up the payment, or check your next bill to see if the discount appears. You can change or cancel automatic payments anytime through your account.

What to do if you need to pay by phone or mail

If you prefer not to pay online, you can call ComEd's automated payment line at 1-877-426-6331 and pay with a debit or credit card over the phone. A representative can also take your payment if you call during business hours, though the automated system is faster.

Mailing a check is still an option, but it takes 7 to 10 business days to reach ComEd and post to your account. Write your account number on the check and mail it to the address on your bill. If your bill is due soon, paying online or by phone is much safer because you'll know immediately whether the payment went through.

Troubleshooting payments that don't post

If you paid online but don't see the payment on your account within two business days, log into your ComEd account and check the payment history. The payment may still be processing. If it's been longer than two business days, call ComEd at 1-877-426-6331 with your confirmation number ready.

ComEd will search their records using your confirmation number and can tell you whether the payment was received. If it was received but hasn't posted yet, they can usually force it through manually. If there's a problem with the payment method (like an expired card), they'll let you know so you can resubmit.

Avoiding late fees and service interruption

ComEd considers a payment late if it arrives after your due date. Online payments made before 8 p.m. Central Time on the due date itself will post in time, but don't wait until the last minute — if the website is slow or you run into a problem, you won't have time to call and pay by phone instead.

If you're behind on your bill, paying online right away is your fastest option. ComEd typically doesn't shut off service the same day a payment is made, but waiting until you receive a disconnection notice puts you at risk. If you're struggling to pay the full amount, contact ComEd before the due date to ask about budget billing or hardship programs.

Frequently Asked Questions

Is there a fee to pay my ComEd bill online?

Credit card payments usually carry a fee of 2 to 3 percent of the amount paid. Debit card and bank account transfers typically have no fee. The website shows the fee before you confirm, so you'll know the exact cost.

Can I pay someone else's ComEd bill online?

You can pay a bill if you have the account number and zip code, but ComEd won't let you set up automatic payments for someone else's account without their permission. If you're paying regularly for a family member, ask them to add you as an authorized user on their account.

What happens if I overpay my bill?

ComEd will credit the overpayment to your next month's bill. If you want a refund instead, contact ComEd and request one — they'll mail it to you, though it takes a few weeks. Most customers let the credit roll over to the next billing cycle.

Can I schedule a payment for a future date?

The website and app don't let you schedule a one-time payment in advance. You can only pay immediately or set up automatic payments for recurring dates. If you want to pay before your due date, you'll need to do it manually each time.

What if my debit card is declined?

ComEd will tell you immediately if the card is declined and won't charge you. Try a different payment method or contact your bank to check if there's a hold on your account. If you use a bank transfer instead, you'll have better success because it pulls directly from your checking account.
