Where and how to pay your Northern Indiana Public Service Company bill
NIPSCO offers several ways to pay your bill: online through their website, by phone, by mail, or in person at payment centers. The fastest and most convenient method is online payment through your NIPSCO account, which processes immediately and requires no fees. If you prefer not to use the internet, you can call their automated phone line, mail a check, or visit a local payment location.
Each payment method has different processing times and requirements. Knowing which option works best for your situation — and when to use it if your bill is due soon — helps you avoid late fees and service interruption.
Key Takeaways
- Online payment through your NIPSCO account is free, immediate, and the fastest way to pay.
- Phone payments are available 24/7 through NIPSCO's automated system, but you will need your account number and a payment method ready.
- Mail payments take 7 to 10 business days to reach NIPSCO, so send them well before your due date to avoid late fees.
- NIPSCO accepts payments at authorized payment centers and retail locations, though you should confirm the location near you is still open before going.
- Setting up automatic payments removes the need to remember due dates and reduces the risk of missed or late payments.
Paying online through your NIPSCO account
Log in to your account at nipsco.com using your account number and password. If you do not have an online account yet, you can create one by selecting "Register" on the login page and providing your account number, email address, and a password. The registration process takes a few minutes and gives you access to your bill history, usage information, and payment options.
Once logged in, select "Pay My Bill" or a similar option (the exact wording may vary slightly). Enter the amount you want to pay — you can pay the full balance, a partial amount, or set up a one-time payment for a future date. Choose your payment method: debit card, credit card, or bank account. NIPSCO does not charge a fee for debit or bank account payments, but credit card payments may include a processing fee. Review the details and confirm the payment. The transaction processes immediately, and you will receive a confirmation number.
Keep your confirmation number for your records. You can also view your payment history in your online account at any time, which is useful if you need to verify that a payment went through or if you are disputing a charge.
Paying by phone 24 hours a day
Call NIPSCO's automated payment line at 1-800-634-3524. You will need your account number (found on your bill) and a payment method ready — either a debit card, credit card, or bank account information. The system will guide you through the payment process step by step.
Phone payments process immediately, just like online payments. You will receive a confirmation number at the end of the call; write it down or note it in your records. If you prefer to speak with a representative instead of using the automated system, you can call during business hours (typically 7 a.m. to 7 p.m. Monday through Friday) and ask to be transferred to a customer service representative who can process your payment manually.
Phone payments may include a processing fee depending on your payment method, similar to online credit card payments. Ask the automated system or the representative about any fees before you complete the transaction.
Mailing a check or money order
Write your check or money order payable to NIPSCO and include your account number on the memo line. Mail it to the address shown on your bill — this address is the payment processing center, not a local office, so sending it to any other address will delay processing.
Mail payments typically take 7 to 10 business days to arrive and be processed. If your bill is due in fewer than 10 days, mailing a check risks a late payment and late fee. For bills due soon, use online payment, phone payment, or an in-person payment center instead. Keep a copy of your check or the front and back of your money order for your records.
Do not include any other documents or correspondence in the envelope with your payment, as this can slow down processing. If you need to include a note about your account, call NIPSCO directly instead.
Paying in person at authorized locations
NIPSCO accepts in-person payments at authorized payment centers and retail locations throughout their service area. Common payment locations include certain grocery stores, pharmacies, and utility payment centers. Visit nipsco.com and use their payment location finder, or call 1-800-634-3524 to confirm which locations near you accept NIPSCO payments and their hours of operation.
Bring your bill or account number and your payment method — cash, check, debit card, or credit card. The payment center will process your payment on the spot and give you a receipt. Keep the receipt as proof of payment. Processing times vary by location, but most in-person payments are recorded within one business day.
Payment centers may charge a convenience fee for accepting your payment, especially if you are paying with a credit card. Ask about any fees before you hand over your payment method.
Setting up automatic payments to avoid missed due dates
Automatic payments remove the need to remember your due date each month. Log into your NIPSCO account online and look for an option labeled "Autopay," "Automatic Payment," or "Recurring Payment." Select this option and choose whether you want to pay the full bill amount or a set dollar amount each month.
Provide your bank account information or debit card details. Choose the date each month when you want the payment to be withdrawn — typically a few days after your bill is issued, or on a date that aligns with your paycheck. Confirm the setup and keep the confirmation number.
You can change or cancel automatic payments at any time through your online account. If your bill amount varies significantly from month to month (which is common with heating or cooling seasons), you may want to set a fixed payment amount rather than paying the full balance, so you can adjust it manually when needed.
What to do if your payment does not show up on your account
If you made a payment but do not see it reflected in your account within the expected timeframe, first check your confirmation number and the payment method you used. Online and phone payments should appear within 24 hours; mail payments take 7 to 10 business days; in-person payments typically appear within one business day.
If the payment is overdue and still missing, call NIPSCO customer service at 1-800-634-3524 during business hours. Have your confirmation number, the date you made the payment, and the amount ready. A representative can look up the payment in their system and tell you whether it has been received and processed, or whether there was an error. If the payment was lost or misdirected, NIPSCO can reissue it or process a replacement payment.
Do not make a second payment until you have confirmed with NIPSCO that the first one did not go through. Making duplicate payments can result in a credit balance on your account, which you will then need to request back.
Frequently Asked Questions
Can I pay my NIPSCO bill with a credit card online without a fee?
No. NIPSCO does not charge a fee for debit card or bank account payments made online or by phone, but credit card payments include a processing fee. The fee amount varies and is shown before you confirm the payment. If you want to avoid the fee, use a debit card or bank account instead.
What happens if I pay after my due date?
NIPSCO will charge a late fee if your payment arrives after the due date shown on your bill. The late fee amount is listed on your bill. If you are more than 30 days late, NIPSCO may disconnect your service. If you know you will be late, call customer service to discuss payment options or a payment plan.
Can I set up automatic payments if I do not have an online account?
You need an online account to set up automatic payments through NIPSCO's website. You can create one for free at nipsco.com. If you do not want to use the website, call 1-800-634-3524 and ask whether a customer service representative can set up automatic payments over the phone.
Is there a way to pay my bill without giving my bank account or card information online?
Yes. You can mail a check, pay in person at an authorized payment center, or call the automated phone line and provide your payment information verbally. Each method has different processing times and possible fees, so choose based on when your bill is due and your comfort level with each option.
What if I overpay my NIPSCO bill?
If you pay more than you owe, the extra amount becomes a credit on your account. You can use the credit toward future bills, or you can request a refund by calling NIPSCO customer service. Refunds typically take one to two billing cycles to process.
