How to Pay Your NJNG Bill Online, by Phone, or Mail

What NJNG is and where to send your payment

NJNG stands for New Jersey Natural Gas, a utility company that delivers natural gas to homes and businesses across central and southern New Jersey. If you receive a bill from NJNG, you are paying for the gas delivered to your property, not electricity or water.

NJNG bills arrive monthly and show your account number, usage, and the amount due. The bill itself lists several ways to pay — online through your account, by phone, by mail, or in person at a payment location. Each method has different timing and requirements, which matters if you are close to a due date.

The company is regulated by the New Jersey Board of Public Utilities, so rates and billing practices follow state rules. If you have questions about your bill amount or usage, NJNG customer service can explain the charges, but the payment methods themselves are straightforward.

Key Takeaways

  • NJNG bills can be paid online through your account at njng.com, by phone at 1-800-221-0051, by mail to the address on your bill, or at authorized payment locations.
  • Online and phone payments usually post within one business day; mailed payments take 7 to 10 business days depending on mail delivery and processing time.
  • Your account number appears on your bill and is required for phone and in-person payments.
  • If your payment is late, NJNG may charge a late fee and eventually disconnect your service, so paying by the due date shown on your bill matters.
  • You can set up automatic monthly payments through your online account to avoid missing a due date.

Paying online through your NJNG account

The fastest and most common way to pay is through the NJNG website. Go to njng.com and log into your account using your account number and password. If you do not have an online account yet, you can create one by entering your account number and the zip code associated with your service address.

Once logged in, select the option to make a payment. You will enter the amount you want to pay and choose a payment method — debit card, credit card, or bank account. NJNG does not charge a fee for debit or bank account payments, but credit card payments may include a processing fee. The payment posts to your account within one business day.

From your online account, you can also set up automatic payments so the same amount is deducted each month on a date you choose. This prevents missed payments and late fees. You can change or cancel automatic payments anytime through your account settings.

Paying by phone or automated system

Call NJNG customer service at 1-800-221-0051 to pay by phone. A representative can take your payment over the phone using a debit card, credit card, or bank account information. Have your account number ready. Phone payments also post within one business day.

Some utility companies offer an automated phone system where you enter your account number and payment information without speaking to a person. Ask NJNG whether this option is available when you call, or check your bill for a separate automated payment phone number.

Paying by phone is useful if you do not have internet access or prefer to speak with someone, but it takes longer than online payment because you have to wait on hold or schedule a callback.

Paying by mail

You can mail a check or money order to the address printed on your NJNG bill. Write your account number on the check or money order so the payment is matched to your account. Mail payments take 7 to 10 business days to arrive and be processed, so send your payment at least two weeks before the due date to avoid a late fee.

Include the payment stub from your bill if possible — it helps NJNG process the payment faster. If you do not have the stub, your account number on the check is enough. Never send cash through the mail.

The mailing address on your bill is the correct one to use. Do not send payment to NJNG's main office or customer service address unless the bill specifically directs you there.

In-person payment locations

NJNG has authorized payment locations where you can pay in person with cash, check, or debit card. These locations include some grocery stores, pharmacies, and check-cashing services in areas served by NJNG. Your bill or the NJNG website lists nearby payment locations.

In-person payments usually post within one business day. This option is useful if you prefer to pay with cash or do not have a bank account or credit card. Call NJNG or check their website to confirm which locations near you accept payments and their hours.

What happens if your payment is late

NJNG bills show a due date, usually 20 to 25 days after the bill is issued. If your payment does not arrive by that date, NJNG charges a late fee. The amount of the late fee is shown on your bill or in your account.

If your payment remains unpaid for 30 to 45 days after the due date, NJNG may send a disconnection notice. This means they can shut off your gas service if the bill is not paid. Once service is disconnected, you must pay the full amount owed plus a reconnection fee to restore gas.

If you cannot pay your full bill by the due date, contact NJNG when ready. They may offer a payment plan or direct you to information programs if you may have access to based on income. Calling before the due date is much better than waiting until after disconnection.

Timing and when to pay

The due date on your bill is the important date for payment to arrive at NJNG, not the day you send it. If you pay online or by phone, your payment posts within one business day, so you can pay up until the day before the due date. If you mail a check, send it at least 10 days before the due date to account for mail delivery and processing.

Weekends and holidays do not stop the clock — if the due date falls on a Saturday or Sunday, NJNG typically treats the following Monday as the due date. Check your bill to confirm.

If you set up automatic payments, the payment is deducted on the date you choose, so pick a date before your due date. If you change your mind about automatic payments, cancel through your online account or call NJNG at least three business days before the scheduled payment date.

Frequently Asked Questions

Can I pay my NJNG bill with a credit card online without a fee?

NJNG does not charge a fee for debit card or bank account payments made online or by phone. Credit card payments may include a processing fee set by the payment processor. Check the fee amount before confirming a credit card payment, or use a debit card or bank account instead to avoid the charge.

What if I pay online but my payment does not show up in my account?

Online and phone payments usually post within one business day. If more than one business day has passed and the payment does not appear, log into your account and check the payment history. If it is not there, call NJNG at 1-800-221-0051 with your confirmation number from the payment to confirm it was received.

Can I set up automatic payments for a different amount each month?

Most automatic payment systems deduct the same amount each month. If your bill varies and you want to pay the full amount due each month, you can log into your account and make a manual payment instead. Some companies offer variable automatic payments, so ask NJNG whether this option exists.

What if I do not have an online account and cannot create one?

You can pay by phone at 1-800-221-0051, by mail, or at an authorized payment location without an online account. You will need your account number, which appears on your bill. Creating an online account is optional — it just makes it easier to pay and view your bill history.

Is there a charge for setting up automatic payments?

NJNG does not charge a fee to set up or use automatic payments. The payment method you choose (debit card, credit card, or bank account) may have a fee, but the automatic payment feature itself is free.
