Log in to your Nicor Gas account at nicorgas.com
Go to nicorgas.com and look for the "Login" button in the top right corner of the homepage. Click it, then enter your account number (found on your paper bill) and your password. If you have never logged in before, you will need to create an account first — select "Register" instead and follow the prompts to set up a username and password.
If you forget your password, click "Forgot Password?" on the login page. Nicor will send a reset link to the email address on file. Check your spam folder if you do not see it within a few minutes. Once you reset your password, you can log in and access your account.
If you do not have an account number handy, look at any recent Nicor bill or statement. The account number is printed near the top, usually next to your name and address. You will need this number every time you log in.

Pay your bill after you log in
Once you are logged in, look for a "Pay My Bill" or "Make a Payment" button on your account dashboard. Click it and you will see your current balance and due date. Enter the amount you want to pay — you can pay the full balance or a partial amount.
Choose your payment method. Nicor accepts direct bank transfers (ACH), which have no fee and are the cheapest option. You can also pay with a credit card or debit card, though Nicor or the card processor may charge a fee for this service. The fee amount will appear on screen before you confirm the payment, so you know the total cost.
Review the payment details one more time, then click "Confirm" or "Submit Payment." You will see a confirmation number on screen — write it down or take a screenshot. Nicor will also send a confirmation email to the address on your account.
When your payment posts and what to expect
Payments made online usually post to your account within one to two business days. If you pay on a Friday evening, expect the payment to show up by Monday or Tuesday. Payments made on weekends or holidays may take longer.
Once your payment posts, your account balance will update and your next bill will reflect the payment. You can log back in anytime to check the status of a recent payment or see your payment history.
If you pay more than you owe, Nicor will hold the overpayment as a credit on your account. The credit will be applied to your next bill automatically. If you want a refund instead, contact Nicor customer service at 1-888-642-6467 and ask them to process a refund check.
Set up automatic payments to avoid missing a due date
Automatic payments mean your bill is paid on the same date each month without you having to log in. To set this up, log in to your account and look for "Autopay," "Automatic Payments," or "Recurring Payments" in the account settings or billing section.
Choose the payment date (usually between the 1st and the 28th of the month) and your payment method. Nicor will deduct the current bill amount from your bank account or card on that date each month. If your bill amount changes, the new amount will be charged the next month.
You can pause or cancel automatic payments anytime by logging back in and turning off the setting. If you cancel, you will need to pay future bills manually or by phone.
Pay by phone if you cannot access the website
Call Nicor Gas customer service at 1-888-642-6467. A representative will ask for your account number and the amount you want to pay. They will take payment over the phone using your bank account or card. This method works the same way as paying online — the payment posts within one to two business days.
Phone payments are available during business hours. Have your account number and payment method ready when you call. If you are calling outside normal hours, you may be able to leave a message, but payment will not be processed until a representative calls you back.
Pay by mail using your bill coupon
Look at your paper bill. At the bottom, you will see a payment coupon with your account number, the amount due, and the due date printed on it. Tear off this coupon and mail it with a check or money order to the address shown on the coupon.
Mail payments take longer to reach Nicor — typically five to seven business days from the time you mail it. To avoid late fees, mail your payment at least one week before the due date. Write your account number on the back of your check so Nicor can match it to your account.
Keep a copy of the coupon or take a photo of it for your records. If you lose the coupon, you can print a new one from your online account or call customer service to request one.
Frequently Asked Questions
What if I enter my account number wrong when I try to log in?
Nicor will show an error message saying the account number or password is incorrect. Double-check that you copied the number exactly as it appears on your bill — it may include letters or be longer than you expect. If you still cannot log in, call customer service at 1-888-642-6467 and they can verify your account number over the phone.
Can I pay someone else's Nicor bill using my account?
No. You can only pay the bill for the account you are logged into. If you want to pay someone else's bill, they need to log in themselves, or you can call customer service and ask them to process a payment over the phone if you have their account number and authorization.
Is there a fee to pay my bill online?
Bank account payments (ACH) have no fee. Credit card and debit card payments may carry a fee charged by Nicor or the card processor — the fee amount will show on screen before you confirm the payment. Paying by phone or mail has no fee.
What happens if I pay after the due date?
Late fees apply if your payment is not received by the due date shown on your bill. Pay as soon as you can to minimize additional charges. If you are having trouble paying, contact Nicor to ask about payment plans or hardship programs that may be available in your area.
Can I change my payment method after I set up automatic payments?
Yes. Log in to your account, go to the automatic payments settings, and update your payment method. The change will take effect on your next scheduled payment date. You can switch between bank account, credit card, and debit card anytime.
