How to pay ComEd: the main routes

ComEd offers several ways to pay your bill, and the fastest method depends on whether you want to pay right now or set up automatic payments. You can pay online through your ComEd account, by phone, by mail, or in person at a payment location. Each method has different timing — some clear the same day, others take several business days.

The online payment portal is the quickest if you have your account number and a checking account or debit card ready. Log into your ComEd account at comed.com, select "Pay My Bill," and follow the prompts. Payments made before 5 p.m. Central Time on a business day typically post the same day. If you pay after 5 p.m. or on a weekend, the payment posts the next business day.

If you prefer not to use the website, you can call ComEd's automated payment line at 1-800-334-7661 and pay by phone with a debit card or checking account. This also processes same-day if you call before 5 p.m. Central Time on a business day. You can also speak to a representative during business hours if you have questions about your bill before paying.

Key Takeaways

  • ComEd's online portal and phone line both process payments the same day if you pay before 5 p.m. Central Time on a business day.
  • Setting up automatic payments through your ComEd account removes the need to remember due dates and can help you avoid late fees.
  • Mailed checks take 7 to 10 business days to reach ComEd, so send them at least two weeks before your due date to avoid a late payment.
  • If you cannot pay the full amount, contact ComEd before the due date to discuss a payment plan or hardship program rather than letting the bill go unpaid.
  • Late payments trigger a reconnection fee and potential service disconnection, so paying on time saves money even if you have to use a payment plan.

Setting up automatic payments to avoid missed due dates

Automatic payments remove the risk of forgetting a due date and incurring a late fee. You can set this up through your ComEd account online or by calling 1-800-334-7661. ComEd will deduct the amount from your checking account or debit card on the date you choose — usually the due date or a few days after.

You have two options: pay the full bill amount automatically each month, or pay a fixed amount if you prefer to manage variable charges yourself. If you choose a fixed amount, make sure it covers at least your base service charge so you do not fall behind. You can change or cancel automatic payments anytime through your account or by calling ComEd.

Automatic payments do not lock you into a contract. If your bill drops significantly or you move, you can adjust the payment amount or stop the arrangement without penalty. This is the simplest way to stay current and avoid reconnection fees.

Paying by mail and understanding the timing

If you prefer to mail a check, write your account number on the check and send it to the address printed on your bill. Do not send cash through the mail. ComEd's mailing address is typically listed on the back of your bill statement.

Mailed payments take 7 to 10 business days to arrive and be processed. If your due date is fewer than 10 days away, mailing a check risks a late payment. Send it at least two weeks before the due date to be safe. If you are cutting it close, use the online portal or phone line instead — both are faster and give you proof of payment immediately.

Keep a copy of your cancelled check or a screenshot of your online payment confirmation for your records. If a payment does not appear on your account within 10 business days of mailing, contact ComEd to confirm it was received.

In-person payment locations and convenience stores

ComEd allows you to pay in person at certain locations, though this option is less common than online or phone payment. Some payment centers and authorized retailers accept ComEd payments, but availability varies by area. Call 1-800-334-7661 to find a location near you that accepts ComEd payments.

In-person payments are processed the same day if you pay before the location's closing time. Bring your account number and the bill itself, or have your account number ready. Ask for a receipt so you have proof of payment.

What happens if you miss a due date or cannot pay the full amount

If your payment is late, ComEd charges a late fee (the amount varies but is typically a percentage of your bill) and may add a reconnection fee if service is shut off. More importantly, ComEd can disconnect your service if you fall 30 days behind. Once disconnected, you must pay the full past-due balance plus a reconnection fee to restore power.

If you cannot pay the full bill by the due date, contact ComEd before the due date — not after. Explain your situation and ask about a payment plan. ComEd may allow you to split the bill into two or three payments over the next month or two. This keeps you current and avoids late fees and disconnection.

ComEd also offers hardship programs for customers facing financial difficulty. These programs may reduce your bill or offer extended payment terms. To learn whether you may be may be able to access, call 1-877-426-6331 or visit the ComEd website. Having your account number and a recent bill ready will speed up the conversation.

Understanding payment deadlines and how to avoid late fees

Your due date is printed on your bill, usually 20 to 25 days after the bill date. This is the date by which ComEd must receive your payment to avoid a late fee. If the due date falls on a weekend or holiday, ComEd typically extends the deadline to the next business day, but do not rely on this — pay by the printed date.

The key timing rule: online and phone payments clear same-day if made before 5 p.m. Central Time on a business day, mailed checks take 7 to 10 days, and in-person payments clear the same day. Plan backward from your due date. If you are paying by mail, send it at least 10 business days early. If you are paying online or by phone, you can pay up until 5 p.m. on the due date itself.

Set a reminder on your phone or calendar for a few days before the due date. This gives you time to pay without rushing and reduces the chance of an accidental late payment.

Frequently Asked Questions

Can I pay my ComEd bill with a credit card?

ComEd does not accept credit card payments directly through their portal or phone line. You can pay only with a checking account, debit card, or by mailing a check. If you want to use a credit card, you could pay your checking account with the card first, then pay ComEd from that account — but this adds a step and may incur credit card fees.

What if I pay online but the payment does not show up on my bill?

Online payments typically post within 24 hours on business days. If more than one business day has passed and the payment still does not appear, log into your account and check the payment history to confirm it was processed. If it shows as processed but your bill still shows unpaid, contact ComEd at 1-800-334-7661 with your confirmation number. Do not assume the payment failed — it may be a display delay.

Can I set up automatic payments if I do not have a checking account?

You can use a debit card for automatic payments if you do not have a checking account. You will need the card number, expiration date, and CVV. Set this up through your ComEd account online or by calling 1-800-334-7661. Make sure the card has sufficient funds on the payment date each month.

What is the reconnection fee if my service is disconnected?

The reconnection fee varies and depends on whether ComEd disconnects you for non-payment or you request reconnection after moving. Call ComEd at 1-800-334-7661 to ask about the current fee. It is typically separate from your past-due balance, so you will owe both to restore service.

Can I change my due date to match my payday?

ComEd does not allow you to change your billing cycle or due date, but you can set up automatic payments on any date you choose within the month. If your payday is the 15th and your due date is the 20th, you can schedule automatic payment for the 15th. Contact ComEd at 1-800-334-7661 to set this up.
