How to Pay Your New Mexico Gas Bill
Where to pay your New Mexico gas bill depends on your utility company
New Mexico has two major natural gas utilities: Atmos Energy (serving central and southern New Mexico) and New Mexico Gas Company (serving northern areas). Each operates its own payment system. Before you can pay, you need to know which company serves your address — check your bill or call your utility directly to confirm.
Both utilities offer multiple payment methods: online through their websites, by phone, by mail, and in person at authorized payment locations. Some also accept automatic bank transfers. The fastest way to pay is usually online, which posts to your account within one business day. Mailed payments take 7 to 10 business days to reach the utility, so mail early if your due date is approaching.
If you are behind on your bill or facing disconnection, contact your utility's customer service line before the due date. Both companies have programs that may help you avoid service interruption, though the specifics vary by company and your situation.

Paying Atmos Energy online and by phone
Atmos Energy operates a customer portal at atmosenergy.com. Log in with your account number (on your bill) and set up online payment in minutes. You can pay once or set up automatic monthly payments. The company also accepts phone payments at 1-844-286-7621 (this number is on your bill). Have your account number and payment method ready when you call.
In-person payment locations vary by area. Atmos Energy accepts payments at many retail partners, but the list changes. Call 1-844-286-7621 or check your bill for the nearest location in your city. Mail payments to the address printed on your bill — include your account number on the check or money order.
Atmos Energy charges a fee for some payment methods. Online payments through their website are usually free, but third-party payment processors may charge a convenience fee. Phone payments may also carry a fee. Ask before you pay if you are using a method other than their website.
Paying New Mexico Gas Company online and by phone
New Mexico Gas Company operates a customer portal at nmmg.com. Create an account or log in, then pay your bill directly through their website. You can make a one-time payment or enroll in automatic monthly payments. The company also accepts phone payments at 1-888-694-6464 (this number is on your bill).
In-person payment options are limited. New Mexico Gas Company does not maintain walk-in payment centers, but you can pay by mail or phone. Mail payments to the address on your bill with your account number clearly marked. Payments sent by mail typically take 7 to 10 business days to post.
New Mexico Gas Company does not charge a fee for online payments made through their website. Phone payments may carry a fee depending on the payment method you choose. Ask the representative the cost before completing the transaction.
Setting up automatic payments and budget billing
Both Atmos Energy and New Mexico Gas Company offer automatic monthly payments, sometimes called autopay. This method deducts your bill from your bank account on a set date each month. To enroll, log into your online account or call customer service. You will need your bank account number and routing number.
Automatic payments reduce the risk of late fees and disconnection because the payment goes through even if you forget. You can change or cancel autopay at any time through your online account or by calling customer service. Most changes take effect within one to two billing cycles.
Both utilities also offer budget billing, which averages your annual gas costs and spreads them evenly across 12 months. This smooths out seasonal spikes in winter heating bills. Budget billing does not lower your total cost — it just makes payments more predictable. Ask your utility whether you are may be able to access and how to enroll.
What to do if you cannot pay by the due date
If you know you cannot pay by your due date, contact your utility before the bill becomes past due. Atmos Energy and New Mexico Gas Company both have programs designed to prevent disconnection. These programs vary, but may include payment plans, bill information, or temporary extensions. Calling early gives you more options than waiting until after disconnection.
Atmos Energy customer service: 1-844-286-7621. New Mexico Gas Company customer service: 1-888-694-6464. Have your account number ready and be prepared to discuss your situation. The utility will explain what programs you may be able to use and what documentation they need.
If you are experiencing financial hardship, ask about bill information programs. New Mexico has state and local programs that may help pay gas bills for low-income households. Your utility can refer you to these programs, or you can contact your local community action agency or 211 (dial 2-1-1 from any phone) to learn what is available in your area.
