You can pay your AES bill online, by phone, or by mail using your account number instead of your full bill

Your account number is the fastest way to pay if you do not have your bill in front of you. AES (formerly DP&L in Ohio and Vectren in Indiana) accepts payments through multiple channels, and your account number works on all of them. You will find this number on your bill, in your online account, or by calling customer service.

The account number is usually a 7 to 10 digit code printed near the top of your bill or in the account details section of the AES website. Using it means you do not need to locate a physical bill, take a photo, or search your email — you can pay in seconds once you have the number memorized or written down.

Key Takeaways

  • Your AES account number appears on your bill, in your online account portal, or by calling 1-800-265-2633 (Ohio) or 1-800-427-2627 (Indiana).
  • Online payment through the AES website or mobile app requires your account number, name, and service address to set up a one-time or recurring payment.
  • Phone payments using your account number take about five minutes and can be made 24/7 through the automated system or a representative.
  • Mail payments should include your account number on the check or money order and be sent to the address printed on your bill.
  • AES does not charge a fee for online or phone payments made through their official channels, but third-party payment processors may add a fee.

Find your account number before you pay

Your account number is printed on every AES bill you receive. Look at the top left or top right of the first page — it is usually labeled "Account Number" or "Acct #" and appears as a series of numbers. If you have a paper bill, this is the quickest place to find it.

If you do not have a recent bill, log into your AES online account at the website for your state (aesohio.com for Ohio customers or aesindiana.com for Indiana customers). Once you sign in, your account number appears in the account summary or account details section. You can also call AES customer service: 1-800-265-2633 for Ohio or 1-800-427-2627 for Indiana. Have your name and service address ready, and a representative will provide your account number.

Pay online using your account number

The AES website and mobile app both accept payments with your account number. Go to aesohio.com or aesindiana.com, select "Pay My Bill," and choose whether you want to pay as a guest or log into your account. If you pay as a guest, you will need your account number, name, and service address.

Enter the amount you want to pay and choose your payment method: debit card, credit card, or bank account. AES does not charge a fee for payments made directly through their website or app. The payment is processed immediately, though it may take one to two business days to appear on your account. If you want to set up automatic recurring payments, log into your account and select the autopay option — this requires your account number and banking details.

Pay by phone with your account number

You can pay 24/7 using AES's automated phone system. Call 1-800-265-2633 (Ohio) or 1-800-427-2627 (Indiana) and follow the prompts to enter your account number using your phone keypad. The system will confirm your account, show your balance, and ask how much you want to pay and what payment method you prefer (debit card or bank account).

If you prefer to speak with a representative, stay on the line after the automated menu or press the option for customer service. A representative can take your payment over the phone and answer questions about your account. Phone payments are processed the same day during business hours and typically appear on your account within one to two business days. There is no fee for paying through AES's official phone line.

Mail a payment with your account number

Write a check or money order for the amount you owe and include your account number on the check itself — write it in the memo line or on the back. This helps AES match the payment to your account even if the envelope gets separated from the check. Include your account number and name on the envelope as well.

Mail your payment to the address printed on your bill under "Make Checks Payable To" or "Payment Address." Payment by mail typically takes 7 to 10 business days to reach AES and another 1 to 2 business days to post to your account, so mail payments are slower than online or phone options. If your bill is due soon, use online or phone payment instead to avoid a late fee.

What to do if you cannot find your account number

If you have lost all your bills and cannot access your online account, call AES customer service with your name and service address. They will look up your account number in their system and read it to you over the phone. This takes about five minutes. Have your driver's license or a recent utility bill from another provider ready to confirm your identity.

If you are a new customer and have not received a bill yet, you may not have an account number assigned. Call AES to confirm your service has been activated and ask for your account number. Once you have it, you can pay online or by phone immediately.

Avoid common payment mistakes

The most common error is writing down the account number incorrectly, which can cause your payment to post to the wrong account or be delayed. Double-check the number before you submit payment online or over the phone. If you are mailing a check, write the account number clearly in the memo line so there is no confusion.

Another mistake is paying through a third-party bill payment service (such as a bank's bill pay feature) and assuming there is no fee. Some banks and payment processors charge a fee to send money to utility companies, even though AES itself does not. Check with your bank before using their bill pay service, or pay directly through AES to avoid surprise charges. Also, if you set up autopay, make sure you have enough money in your account on the due date — a failed payment can result in a late fee.

Frequently Asked Questions

Can I pay my AES bill with just my account number and no other information?

Online and by phone, you will need your account number plus your name and service address to confirm your identity. By mail, your account number alone is enough if you write it clearly on the check. For guest online payments, AES requires all three pieces of information to process the transaction.

Is there a fee to pay my AES bill online or by phone?

No. AES does not charge a fee for payments made directly through their website, mobile app, or phone line. However, if you pay through your bank's bill pay service or a third-party payment processor, that service may charge a fee. Always pay directly through AES to avoid extra charges.

How long does it take for my payment to show up on my account?

Online and phone payments typically post within one to two business days. Mail payments take 7 to 10 business days to arrive at AES plus another 1 to 2 business days to post. If your bill is due soon, do not use mail — pay online or by phone instead.

What if I pay with the wrong account number by mistake?

Call AES customer service right away with your confirmation number from the payment. They can trace the payment and move it to the correct account if you provide the right account number. The sooner you call, the faster they can fix it.

Can I set up automatic payments using my account number?

Yes. Log into your AES online account, go to the autopay or recurring payment section, and enter your account number and banking details. AES will deduct the amount you choose on your due date each month. You can change or cancel autopay anytime through your account.
