Southwest Gas phone numbers by state and service type

Southwest Gas operates in Arizona, Nevada, and New Mexico. The phone number you need depends on which state you live in and what you're calling about. The company handles billing questions, service requests, emergencies, and account changes through different lines.

For Arizona customers, call 602-221-7700 for general service and billing. For Nevada customers, call 702-709-4700. For New Mexico customers, call 505-529-2711. These numbers handle routine account questions, payment arrangements, and service requests during business hours.

If you have a gas leak or smell gas, do not call the regular customer service line. Hang up and call 911 when ready, then call the emergency line for your state. Arizona emergency: 602-221-7700 (press option for emergency). Nevada emergency: 702-709-4700 (press option for emergency). New Mexico emergency: 505-529-2711 (press option for emergency). These lines operate 24 hours a day.

  • Southwest Gas also offers online account management through their website if you prefer not to call.

What you can handle online instead of calling

Southwest Gas lets you manage many account tasks through their website without waiting on hold. You can view your bill, make a one-time payment, set up automatic payments, report a service outage, and update your contact information online. If you have an account with them, log in at swgas.com to access these options.

The online portal also shows your usage history and lets you set up budget billing, which spreads your annual gas costs evenly across 12 months. This can help you predict your winter heating bills. You can also enroll in paperless billing and receive your statements by email instead.

When you need to speak to someone right away

If you call during business hours (typically 7 a.m. to 6 p.m. Monday through Friday), you will reach a representative faster than during evening or weekend hours. Have your account number ready — it appears on your bill and speeds up the call. If you do not have your account number, the representative can look up your account using your phone number or service address.

For payment arrangements or questions about a past-due bill, calling is often faster than email because the representative can discuss options when ready and sometimes adjust your account on the spot. If you are calling about a service outage, the system will tell you how many customers are affected and when power is expected to be restored.

Billing and payment questions

If your bill is higher than usual, the representative can walk you through what changed — seasonal heating use, a rate adjustment, or a meter reading issue. They can also discuss payment plans if you cannot pay the full amount. Southwest Gas offers several options, including extended payment arrangements for customers facing hardship.

You can also ask about budget billing during a call, which locks in an average monthly payment based on your usage history. This means your winter bills will be lower and your summer bills higher, but the total stays roughly the same year-round. The representative can enroll you when ready if you meet the program requirements.

Service requests and outages

If your gas is not working or you smell gas but it is not an emergency, call your state's main number and describe the problem. The representative will determine whether you need an emergency visit or a scheduled appointment. For non-emergency issues like a pilot light that will not stay lit or low pressure, appointments are usually available within a few days.

If there is a widespread outage in your area, the automated system will tell you how many customers are affected and provide an estimated restoration time. You can also report an outage online through the website, which sometimes updates faster than the phone system during large events.

Account changes and new service

If you are moving to a new address within Southwest Gas's service area, call to set a disconnect date at your old address and a connect date at your new one. The representative will coordinate the timing so you do not have a gap in service. If you are moving outside the service area, they will also walk you through the final bill process.

If you are a new customer, you can set up service by phone or online. You will need your service address, a photo ID, and proof of residency (a recent utility bill or lease). The representative can schedule your connection and discuss deposit requirements, which vary by state and credit history.

Frequently Asked Questions

What should I do if I smell gas?

Leave the building when ready and call 911 from a safe location. Do not use your phone inside the building, do not turn lights on or off, and do not start your car. Once you are safe, call your state's Southwest Gas emergency line to report the leak.

Can I pay my bill over the phone?

Yes. Call your state's main number and a representative can process a one-time payment using a debit card or bank account. You can also pay online at swgas.com without calling. Payments made before 5 p.m. usually post the same day.

How do I set up automatic payments?

Log into your account at swgas.com and select the autopay option, or call your state's number and ask a representative to enroll you. Automatic payments deduct from your bank account or card on your bill due date each month. You can change or cancel anytime.

What if I cannot pay my full bill?

Call to discuss a payment arrangement. Southwest Gas offers extended plans that spread your balance over several months. Representatives can also discuss hardship programs if you are facing financial difficulty. Have your account number and recent bill ready when you call.

How do I report an outage?

Call your state's main number or report it online at swgas.com. Provide your service address and describe what is not working. The system will tell you if others in your area are affected and when service is expected to return.
