How to pay your Nicor Gas bill

Nicor Gas offers four main ways to pay your bill: online through your account, by phone, through automatic bank withdrawals, or by mailing a check. The fastest method is online payment through the Nicor Gas website or mobile app, which processes when ready and lets you see your payment history. If you prefer not to use the internet, you can call Nicor's payment line or set up autopay so the bill comes out of your bank account on a date you choose.

Your bill arrives monthly and shows your account number, the amount due, and the due date — usually about 20 days after the bill date. Paying online or by phone takes a few minutes. Mailed payments need to arrive by the due date to avoid a late fee, so plan for mail delivery time.

Key Takeaways

  • Online payment through Nicor's website or app is the fastest option and shows your payment when ready.
  • Automatic bank withdrawal (autopay) removes the need to remember to pay each month and can reduce your bill by a small amount.
  • Phone payments are available 24/7 by calling Nicor's automated line or speaking to a representative during business hours.
  • Mailed checks must arrive by the due date printed on your bill to avoid late fees.
  • Your account number appears on your bill and is required for all payment methods.

Paying online through your Nicor account

Go to nicorgas.com and sign in with your username and password. If you do not have an online account yet, you can create one by entering your account number and zip code. Once logged in, select "Pay My Bill" or "Make a Payment" — the exact wording varies slightly depending on whether you are on the website or mobile app.

Enter the amount you want to pay (you can pay the full bill or a partial amount) and choose your payment date. Nicor accepts payments from a bank account or debit card. If you use a debit card, Nicor charges a small fee (typically $2 to $4 depending on the card type); bank account payments have no fee. Review the details and confirm. Your payment processes when ready, and you will see a confirmation number on screen and receive an email receipt.

Keep your confirmation number in case you need to reference the payment later. Your online account also shows your payment history, so you can check whether previous payments went through.

Setting up automatic payments from your bank account

Autopay is the most hands-off option. You authorize Nicor to withdraw your bill amount from your bank account on a date you choose — usually a few days before the due date. To set this up, log into your Nicor account online, go to "Billing" or "Payment Options," and select "Enroll in AutoPay." You will need your bank account number and routing number.

Nicor typically offers a small discount (usually $0.50 to $1.00 per month) if you enroll in autopay. Once enrolled, you do not have to do anything each month — the payment comes out automatically. You can change the payment date or cancel autopay at any time through your online account.

If your bill amount varies significantly month to month (as gas bills often do in winter), you can set up autopay to pay a fixed amount and adjust it manually when needed, or you can let it pay the full bill each month. Check your account settings to see which option is available.

Paying by phone

Call Nicor's automated payment line at 1-888-642-6748. You will need your account number, which is on your bill. The automated system will read your current balance and ask how much you want to pay. You can pay from a bank account (no fee) or debit card (small fee applies). The system will confirm your payment and give you a confirmation number.

If you prefer to speak to a person, you can call during business hours (typically Monday through Friday, 7 a.m. to 7 p.m. Central Time) and a representative will process your payment. Phone payments process the same day if made before a certain cutoff time (usually late afternoon); payments made after hours or on weekends process the next business day.

Mailing a check or money order

Write your check or money order for the amount due and include your account number on the check. Mail it to the address shown on your bill — this address changes depending on which payment processing center handles your account, so always use the address on your current bill rather than a memorized address.

Mail your payment at least one week before the due date to account for delivery time. The due date is printed on your bill. If your payment arrives after the due date, Nicor may charge a late fee. Keep a copy of your check or the cancelled check as your receipt.

What to do if you cannot pay by the due date

If you know you cannot pay by the due date, contact Nicor before the due date passes. Call 1-888-642-6748 or log into your online account to see if a payment arrangement or extension is available. Nicor may be able to defer your payment or set up a plan to pay over time, depending on your account history and the amount owed.

If your bill goes unpaid past the due date, Nicor will charge a late fee and may eventually disconnect your service. If you are having trouble paying, Nicor also offers information about energy information programs in your area — ask when you call, or check the "information Programs" section of the Nicor website.

Understanding your bill and payment important date

Your Nicor bill shows the service period (the dates the bill covers), the amount due, and the due date. The due date is typically 20 days after the bill date. Your bill also shows your account number, which you need for any payment method except online (if you are already logged into your account).

If you pay online or by phone before the due date, your payment posts when ready and you will not be charged a late fee. If you mail a check, it must arrive by the due date. If you set up autopay, the payment comes out on the date you selected, so choose a date before the due date to be safe.
