Where to send your payment and what information you need
New Mexico Gas Company (NMGC) accepts payments through several channels: online at their website, by phone, by mail, or in person at authorized payment locations. The fastest way is online or by phone, both of which post to your account within one business day. By mail takes 7 to 10 business days, so send it early if your due date is approaching.
Before you pay, have your bill in front of you. You will need your account number (an 8 to 10 digit number printed on the front of your bill) and the amount due. If you are paying by mail, write your account number on the check or money order and mail it to the address shown on your bill — this address varies by service area, so do not use a generic company address.
If you do not have your bill, you can look up your account online using your service address and zip code, or call NMGC customer service at 1-888-694-6462 to confirm the amount and due date before paying.
Key Takeaways
- Online and phone payments post within one business day; mail payments take 7 to 10 days, so plan ahead if your due date is soon.
- You need your account number (printed on your bill) and the amount due to pay by any method.
- The mailing address for payments is printed on your bill and varies by service area — using the wrong address delays posting.
- NMGC offers automatic payment through their website, which removes the need to remember due dates each month.
- If you cannot pay the full amount by the due date, contact NMGC before the bill becomes past due to discuss payment arrangements.
Paying online through the NMGC website
Go to the New Mexico Gas Company website and select "Pay My Bill" or "Make a Payment." You will be asked to enter your account number and zip code to pull up your account. The site will show your current balance, due date, and payment history.
Enter the amount you want to pay (you can pay less than the full amount if needed, though the full amount is due by the due date). Choose your payment method: debit card, credit card, or bank account. Credit and debit card payments charge a convenience fee of around 2.5% of the payment amount; bank account payments have no fee. Review the total including any fee, then confirm the payment.
You will receive a confirmation number immediately. Write it down or take a screenshot. The payment posts to your account within one business day, and you can check the status by logging back into your account.
Paying by phone or setting up automatic payments
Call NMGC customer service at 1-888-694-6462 to pay by phone. Have your account number and payment method ready. A representative will confirm your account, the amount due, and process the payment over the phone. Phone payments accept debit cards, credit cards, and bank accounts. Like online payments, credit and debit card payments charge a convenience fee; bank account payments do not.
If you want to stop worrying about due dates, set up automatic payments (sometimes called autopay or recurring payments) through the NMGC website or by calling customer service. You authorize NMGC to withdraw the amount due from your bank account on or near your due date each month. There is no fee for automatic bank account payments. You can change or cancel automatic payments anytime through your online account or by calling customer service.
Paying by mail or at a payment location
If you prefer to mail a check or money order, write your account number on the front of the check. Include the payment stub from your bill if you have it. Mail to the address printed on your bill — do not use a general company address, as NMGC has multiple service areas with different mailing addresses. Allow 7 to 10 business days for the payment to reach NMGC and post to your account.
NMGC also accepts payments at certain authorized locations in New Mexico, such as utility payment centers and some retail stores. Call 1-888-694-6462 or check the NMGC website to find a payment location near you. Payments made in person typically post within one to two business days.
What to do if you cannot pay by the due date
If you know you cannot pay the full bill by the due date, contact NMGC before the due date passes. Call 1-888-694-6462 and explain your situation. NMGC may be able to set up a payment arrangement — a plan that lets you pay part of the bill now and the rest over a set number of weeks. Payment arrangements vary based on your account history and the amount owed.
If you do not contact NMGC before the due date, your account will be marked past due. NMGC may charge a late fee (the amount varies) and can eventually disconnect your service if the bill remains unpaid. Contacting them early gives you more options and may help you avoid late fees and disconnection.
Understanding your bill and due date
Your NMGC bill shows the amount due, the due date, and the service period (the dates the bill covers). The due date is usually 20 to 25 days after the bill is issued. If the due date falls on a weekend or holiday, NMGC typically extends it to the next business day, though you should confirm this on your bill.
The bill also shows your account number, service address, and a breakdown of charges: the cost of gas used, delivery charges, taxes, and any other fees. If you have questions about specific charges, call customer service before paying. Paying the bill does not mean you agree with every charge — you can dispute charges separately if you believe there is an error.
Frequently Asked Questions
Is there a fee to pay my NMGC bill online?
Credit and debit card payments charge a convenience fee of approximately 2.5% of the payment amount. Bank account payments have no fee. Phone and mail payments also have no fee if you use a bank account or check.
How long does it take for my payment to show up on my account?
Online and phone payments post within one business day. Mail payments take 7 to 10 business days. In-person payments at authorized locations typically post within one to two business days. Do not assume your payment has posted until you see it in your online account.
Can I pay part of my bill now and the rest later?
You can make a partial payment anytime, but the full amount is still due by the due date. If you cannot pay the full amount by the due date, contact NMGC before the due date to set up a payment arrangement, which spreads the balance over multiple weeks.
What happens if I miss the due date?
Your account becomes past due and NMGC may charge a late fee. If the bill remains unpaid, NMGC can disconnect your service. Contact customer service as soon as possible to discuss payment options or a payment arrangement.
Can I change or cancel automatic payments?
Yes. Log into your NMGC online account and adjust your autopay settings, or call customer service at 1-888-694-6462. Changes take effect within one to two billing cycles.
