Call Nicor Gas customer service at 1-888-642-6467 to pay by phone
Nicor Gas accepts phone payments 24 hours a day, 7 days a week. When you call, have your account number ready — you'll find it on your bill or in your online account. The automated system will walk you through payment options and take your payment information directly.
Phone payments are processed immediately, though the funds may take one to two business days to appear on your account depending on your bank. If you pay after 11:59 p.m. Central Time, the payment is typically recorded as received the next business day.
Nicor Gas does not charge a fee for phone payments made through their main customer service line. Some third-party payment services charge fees, so confirm you're calling the official Nicor number before providing payment details.

What information you need before calling
Gather these details before you dial so the call moves faster. Your account number appears on your Nicor Gas bill in the upper right corner or in the account summary section. If you don't have a physical bill, log into your online account at nicorgas.com and find it there.
You'll also need the payment amount — either the full bill or a partial payment. Nicor allows you to pay any amount toward your balance, not just the full bill due. Have your checking account or debit card information ready if you plan to pay that way.
If you're calling about a past-due balance or a disconnect notice, have that notice in front of you. The customer service representative can see your account history, but having the notice helps you explain your situation quickly.
Payment methods accepted over the phone
Nicor Gas accepts checking account payments (ACH transfers) and debit card payments over the phone. Both are processed the same day you call, though the funds may take one to two business days to clear your bank account.
Credit card payments are not accepted through the phone line. If you want to pay with a credit card, use the online payment portal at nicorgas.com or call to ask about third-party payment services — though those services typically charge a convenience fee.
You cannot pay with cash or check over the phone. If you need to pay by mail or in person, Nicor provides payment locations and mailing addresses on their website and on your bill.
When your payment posts to your account
Phone payments made before 11:59 p.m. Central Time are recorded as received that same day. Payments made after 11:59 p.m. are recorded as received the next business day. The actual funds may take one to two business days to transfer from your bank to Nicor, but your account shows the payment received date immediately.
If you're trying to avoid a late fee or disconnect, the received date is what matters — not the date the money clears your bank. Calling before midnight Central Time ensures your payment is recorded on the day you call.
If you need the payment to post by a specific date because of a disconnect notice or court date, tell the customer service representative. They can note your account and may be able to work with you on timing.
What to do if you can't reach customer service
If the phone line is busy or you prefer not to call, Nicor Gas offers payment options online at nicorgas.com. Log into your account and select "Pay My Bill" to pay immediately with a checking account or debit card at no charge.
You can also set up automatic recurring payments through your online account so you don't have to call or log in each month. Choose the payment date and amount, and Nicor will withdraw the payment automatically on that date.
If you're having trouble with your account or need to discuss payment arrangements, customer service representatives are available Monday through Friday during business hours. The phone number remains 1-888-642-6467.
Common reasons the phone line may be slow
During winter months (November through March), Nicor experiences higher call volume because more customers are using gas for heating. If you reach a long wait time, try calling early in the morning or late in the evening when fewer people are calling.
The first few days after a bill is due also see heavier call traffic. If your bill isn't urgent, waiting a few days after the due date can mean shorter wait times — though you'll want to pay before any late fees apply.
If you're calling about a disconnect notice or emergency situation, tell the automated system or the representative immediately. Nicor prioritizes these calls and may move you ahead in the queue.
Frequently Asked Questions
Is there a fee to pay by phone?
No. Nicor Gas does not charge a fee when you pay through their official customer service line at 1-888-642-6467. Some third-party payment services charge convenience fees, so always confirm you're calling the official Nicor number before providing payment information.
Can I pay someone else's Nicor bill by phone?
You can pay if you have the account number and authorization from the account holder. The automated system will ask for the account number, not a name, so you don't need to be the person whose name is on the bill. However, Nicor may ask security questions to verify you're authorized to make the payment.
What happens if I pay the wrong amount by mistake?
If you overpay, Nicor will credit the extra amount to your account and apply it to your next bill. If you underpay and want to pay the rest, you can call back and make another payment. There's no penalty for making multiple payments in one month.
Can I set up a payment plan over the phone?
Customer service representatives can discuss payment arrangements if you're unable to pay your full bill. Call 1-888-642-6467 and explain your situation. Nicor may offer a payment plan, but you'll need to speak with a representative during business hours — the automated system handles payments only.
How long does a phone payment take to show up online?
Your payment appears in your online account within a few hours of calling, showing the date it was received. The actual funds may take one to two business days to transfer from your bank, but your account balance updates immediately after the call.
