What to have ready before you call
Before calling Nicor Gas, gather your account number, which appears on your bill or in your online account. If you are calling about a specific charge or service issue, have the date and details in front of you. This speeds up the call and helps the representative find your information faster.
If you are calling about a service appointment or repair, know your address and the best times for a technician to reach you. Nicor Gas schedules appointments during specific windows, so having your availability ready helps you book the time that works best.
Billing and payment questions
Nicor Gas handles billing questions through the same main number. You can ask about your bill amount, payment due dates, budget billing options, or past charges. Representatives can also help you set up automatic payments or change your payment method.
If you want to pay your bill without calling, you can do so online at nicorgas.com, by mail, or by phone using an automated system. Paying online is usually fastest and gives you an when ready confirmation. Mail payments take longer to process, so send them at least 10 days before your due date to avoid a late fee.
Service outages and gas smell reports
If your gas service has stopped and you are not sure why, call the main number and select the option for outages. Nicor Gas can tell you whether the outage is in your area, when service is expected to return, and whether you need a technician to visit your home. Some outages affect entire neighborhoods; others are specific to one building or line.
If you smell gas but do not suspect a leak in your home, call the non-emergency line to report it. Nicor Gas will send a technician to check the street or outdoor lines. Do not ignore a gas smell — even a faint one can signal a problem that needs attention.
Account changes and service requests
To add or remove a name from your account, change your billing address, or update your contact information, call customer service. You can also make some of these changes online through your account portal. Service requests like installing a new meter or upgrading your line also go through the main number, and a representative will schedule a technician visit.
If you are moving and need to close your account, call at least two weeks before your move date. Nicor Gas will schedule a final meter reading and process your final bill. Closing your account early can result in charges, so ask about any fees when you call.
Nicor Gas online account management
The Nicor Gas website at nicorgas.com lets you handle many tasks without calling. You can view your bill, pay online, set up autopay, check your usage, and report an outage. Creating an online account takes a few minutes and requires your account number and service address.
The website also has a chat feature during business hours if you prefer to type rather than call. Chat is often faster than the phone line during busy times, and you get a transcript of the conversation for your records.
