NMGCO bill pay basics

New Mexico Gas Company (NMGCO) 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 NMGCO account, which processes immediately and requires no fees. You can also set up automatic payments so your bill is paid on the same date each month without you having to remember.

To pay online, you'll need your account number (found on your bill) and either a bank account or credit/debit card. Payment by phone goes through their customer service line, and mail payments should be sent to the address printed on your bill. NMGCO does not charge extra for any of these payment methods, though your bank may charge a fee if you use a credit card.

Key Takeaways

  • Online payment through NMGCO's website is free and processes the same day, making it the fastest way to pay.
  • Automatic payments remove the need to remember your due date and can be set up or cancelled anytime through your account.
  • Phone and mail payments are available but take longer — mail typically takes 7 to 10 business days to reach NMGCO.
  • Your account number appears on your bill and is required for all payment methods except in-person payments at authorized locations.
  • NMGCO does not charge fees for any payment method, but your bank may charge a fee if you pay with a credit card instead of a debit card or bank account.

Setting up online payment on the NMGCO website

Go to the NMGCO website and select "Pay My Bill" or "Online Bill Pay." You'll be asked to log in or create an account using your account number and service address. If you don't have an online account yet, you can create one in a few minutes by entering your account number and the zip code associated with your service address.

Once logged in, select the amount you want to pay and choose your payment method: bank account (ACH transfer) or debit/credit card. Bank account payments are free and process the same day if submitted before 5 p.m. Mountain Time. Card payments also process the same day but may carry a fee from your card issuer, not from NMGCO. Review the payment details, confirm the due date, and submit.

Automatic payments and how to manage them

Automatic payments let NMGCO withdraw your bill amount from your bank account or charge your card on the same date each month. To set this up, log into your online account, go to the "Autopay" or "Automatic Payment" section, and choose your payment method and preferred payment date. Most customers choose a date shortly after their bill arrives, giving them time to review the charges before payment is taken.

You can change or stop automatic payments anytime through your account without penalty. If you need to pause payments temporarily — for example, if you're disputing a charge or waiting for a billing correction — you can suspend autopay for one or more months and restart it later. Keep in mind that if you cancel autopay, you'll need to remember to pay manually each month or you may face a late fee.

Paying by phone or mail

To pay by phone, call NMGCO's customer service number listed on your bill. Have your account number and payment method ready. A representative will process your payment over the phone, and you'll receive a confirmation number. Phone payments are free and typically process within one business day, though the funds may take longer to appear on your account depending on your bank.

Mail payments should be sent to the address shown on your bill. Write your account number on the check or money order and allow 7 to 10 business days for the payment to arrive and be processed. If your payment is late by the time it arrives, you may be charged a late fee even though you mailed it on time, so mail is best used only when you have extra time before your due date. Keep a copy of your check or a photo of the money order for your records.

In-person payment locations

NMGCO accepts in-person payments at their office locations and at authorized payment centers throughout New Mexico. Payment centers are often located at grocery stores, pharmacies, or utility payment kiosks. In-person payments are processed immediately, and you'll receive a receipt on the spot. This method works well if you prefer to pay with cash or if you want a same-day confirmation.

To find a payment location near you, check the NMGCO website or call customer service. Hours vary by location, so confirm the hours before you go. In-person payments are free, and you'll need your account number or the bill itself to complete the transaction.

What to do if your payment is late

If your payment doesn't arrive by the due date shown on your bill, NMGCO will charge a late fee. The amount varies but is typically a percentage of your bill or a flat fee — check your bill or account for the exact amount. A late payment may also affect your credit report if it's reported to credit bureaus, though this usually happens only after 30 days past due.

If you're having trouble paying on time, contact NMGCO customer service to discuss your options. They may offer a payment plan, a temporary extension, or information about hardship programs that could help. Acting before your bill becomes severely overdue gives you more options and may prevent service disconnection.

Avoiding common payment mistakes

One common mistake is mailing a check without allowing enough time for it to arrive. Mail can take 7 to 10 business days, so if your due date is less than two weeks away, use online or phone payment instead. Another mistake is paying with a credit card without realizing your bank will charge a fee — using your debit card or bank account directly avoids this cost.

A third mistake is setting up automatic payments but forgetting to update them if your bank account or card changes. If your payment method expires or is closed, your autopay will fail and you'll be marked late. Check your autopay settings once a year to make sure the payment method is still active. Finally, don't assume a payment has gone through just because you submitted it — log back into your account within a day to confirm it was processed.

Frequently Asked Questions

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

NMGCO does not charge a fee for credit card payments, but your credit card issuer may charge a cash advance or convenience fee. Using your debit card or bank account (ACH transfer) avoids this fee entirely. Check with your card issuer about their specific fees before you pay.

What happens if I pay online but my payment doesn't show up on my account?

Online payments typically process the same day if submitted before 5 p.m. Mountain Time. If you don't see the payment reflected within one business day, log back into your account to check the status. If it still shows as pending, contact NMGCO customer service with your confirmation number and they can investigate.

Can I change my automatic payment date if it doesn't work with my paycheck schedule?

Yes. Log into your NMGCO account, go to the autopay settings, and select a new payment date. You can choose any date between the 1st and the 28th of the month. Changes take effect on your next billing cycle, so update it well before your current due date.

Is there a penalty for cancelling automatic payments?

No. You can cancel autopay anytime through your account without any penalty or fee. If you cancel, remember that you'll need to pay manually each month or you may be charged a late fee.

What should I do if I can't afford to pay my full bill?

Contact NMGCO customer service to discuss a payment plan or to learn about hardship programs. Many utilities offer extended payment plans or assistance programs for customers facing financial difficulty. Reaching out before your bill becomes severely overdue gives you more options.
