How to Pay Your Pepco Electric Bill Online, by Phone, or Mail

Pepco bill payment methods and where to send money

Pepco, the electric utility serving Washington DC, Maryland, and parts of Virginia, offers several ways to pay your bill: online through your account, by phone, by mail, or in person at payment centers. The method you choose depends on how quickly you need the payment posted and whether you want to set up automatic payments. Each route has different processing times, so knowing the difference matters if you are close to a due date.

Your bill arrives monthly and shows a due date — typically 21 days after the bill date. Pepco applies payments in the order they receive them, so a payment mailed on the due date may arrive after the cutoff and trigger a late fee. Understanding when each payment method actually reaches Pepco helps you avoid that.

Key Takeaways

• Online payments through your Pepco account post the same day if submitted before 5 p.m. ET on a business day, or the next business day otherwise.
• Phone payments (1-877-737-2662) process when ready and are recorded the same business day, but you will need your account number and a checking or savings account.
• Mail payments take 7 to 10 business days to reach Pepco's processing center, so sending a check on the due date will likely arrive late and incur a late fee.
• Automatic payments (autopay) withdraw money on a date you choose each month and eliminate the risk of missing a due date.
• Late payments trigger a 1.5% monthly charge on the unpaid balance, so confirming your payment method's processing time prevents unexpected fees.

Paying online through your Pepco account

Log into your account at pepco.com, select "Pay My Bill," and enter the amount you want to pay. You can pay with a checking account, savings account, or debit card. Payments submitted before 5 p.m. ET on a business day post the same day; payments submitted after 5 p.m. or on weekends and holidays post the next business day.

Online payments are free when you use a bank account (checking or savings). Paying with a debit or credit card incurs a convenience fee of roughly 2.5% of the payment amount, charged by the third-party processor, not by Pepco. If you pay $100 with a debit card, expect to pay about $2.50 extra.

You do not need to create a separate online account to pay once — you can make a one-time payment without logging in by visiting pepco.com/paybill and entering your account number and the amount. One-time payments follow the same posting schedule as account-based payments.

Paying by phone

Call Pepco's automated payment line at 1-877-737-2662 to pay by phone. The system accepts payments from a checking or savings account only — not credit or debit cards. Have your Pepco account number and bank account information ready. The payment is recorded when ready and posts the same business day.

Phone payments are free and process faster than mail, but you cannot dispute a payment once you have confirmed it to the automated system. If you make a mistake, you will need to contact Pepco to request a reversal or credit.

Paying by mail

Write a check or money order, include your account number on the back, and mail it to the address on your bill. Pepco's mailing address is typically listed in the "Payment" section of your statement. Mail payments take 7 to 10 business days to reach the processing center after you drop them in the mail.

Because of this delay, mailing a check on the due date almost always results in a late payment. Pepco records the payment date as the day it arrives at their processing center, not the day you mailed it. If your due date is the 21st and you mail a check on the 21st, it will likely arrive on the 28th or later, triggering a late fee. Mail payments only make sense if you are paying well before the due date or if you do not have online or phone access.

Setting up automatic payments (autopay)

Automatic payments withdraw money from your bank account on a date you choose each month, usually between the 1st and the 28th. Log into your Pepco account, go to "Billing & Payment," select "Autopay," and choose your bank account and payment date. Pepco processes autopay withdrawals the day you select, so if you choose the 20th and your due date is the 21st, the payment arrives on time.

Autopay is free and eliminates the risk of forgetting a payment or miscalculating mail time. You can change or cancel autopay anytime through your account, and you can make additional one-time payments in months when you want to pay more than your regular bill.

Late payments and what happens if you miss the due date

If your payment does not arrive by the due date shown on your bill, Pepco charges a late fee of 1.5% per month on the unpaid balance. On a $150 bill, a late fee adds $2.25 to what you owe. The fee compounds monthly, so if you remain unpaid for two months, the second month's fee is calculated on the original bill plus the first month's fee.

After 30 days past due, Pepco may disconnect your service. You will receive a disconnection notice before this happens, usually giving you 10 days to pay or contact Pepco to arrange a payment plan. If your service is disconnected, reconnection requires payment of the full past-due balance plus a reconnection fee.

Frequently Asked Questions

What if I pay online but my payment does not show up by the due date?

If you submitted the payment before 5 p.m. ET on a business day, it should post the same day. Check your account to confirm the payment went through. If it did not process, contact Pepco at 1-877-737-2662 to verify the payment was received. If you submitted it after 5 p.m. or on a weekend, it will post the next business day.

Can I pay my Pepco bill at a store or payment center?

Pepco does not operate payment centers, but some third-party locations may accept Pepco payments for a fee. Check pepco.com or call 1-877-737-2662 to find authorized payment locations near you. These payments typically take 1 to 2 business days to post and may carry a processing fee.

What happens if I set up autopay but want to skip a month?

You can pause or cancel autopay anytime through your online account without penalty. If you need to skip just one month, cancel autopay, make a one-time payment when you are ready, and then restart autopay for the following month.

Is there a discount for paying on time or setting up autopay?

Pepco does not offer a discount for on-time payment or autopay enrollment. However, autopay eliminates the risk of late fees, which saves you money by preventing the 1.5% monthly charge on unpaid balances.

Can I dispute a payment I made by phone?

Once you confirm a phone payment to the automated system, you cannot cancel it. If you made an error, contact Pepco at 1-877-737-2662 to request a credit or reversal. Pepco will investigate and may issue a credit to your account if the payment was made in error.
