Columbia Gas phone numbers by state and service type

Columbia Gas operates in four states — Ohio, Kentucky, Pennsylvania, and Massachusetts — and each state has its own customer service phone line. The company does not have a single national number. Your state determines which number to call.

For Ohio, call 1-800-344-4077. For Kentucky, call 1-800-432-9346. For Pennsylvania, call 1-800-752-7520. For Massachusetts, call 1-800-752-7520 (the same as Pennsylvania). These numbers connect you to customer service representatives who handle billing questions, service requests, and account changes.

If you do not know which state your service is in, check your most recent bill — it will show your state and the correct phone number. You can also look up your address on the Columbia Gas website for your state to confirm which division serves your area.

What to have ready before you call

When you call Columbia Gas, have your account number on hand. Your bill shows this number at the top or in a highlighted box. If you cannot find your account number, you can still reach customer service by providing your street address and the name on the account, but the call will take longer.

If you are calling about a specific problem — a high bill, a service interruption, a meter issue — write down the dates and amounts involved before you dial. This speeds up the conversation and helps the representative understand what happened. If you have already received a notice or letter from Columbia Gas, have that in front of you as well.

When Columbia Gas phone lines are open

Customer service hours vary slightly by state, but most Columbia Gas divisions operate Monday through Friday from 7 a.m. to 7 p.m. local time. Saturday hours are typically 8 a.m. to 5 p.m., and Sunday hours are 10 a.m. to 4 p.m. Some divisions may have different weekend schedules, so confirm the hours for your state before calling outside normal business days.

If you call outside these hours, you will reach an automated system that can handle some requests — such as reporting a gas leak or outage — or you can leave a message for a representative to return your call during business hours. For emergencies like a gas smell or suspected leak, follow the automated prompts to reach someone when ready, regardless of the time.

Reporting a gas leak or emergency

If you smell gas or suspect a leak, do not use your phone indoors. Leave your home or building when ready and move to a safe distance. Once you are outside, call Columbia Gas from a mobile phone or a neighbor's phone. The automated system will recognize "gas leak" or "emergency" and route you to someone who can respond right away, even outside normal business hours.

Do not turn electrical switches on or off, do not light a match or lighter, and do not start your car in the garage. These actions can ignite gas. Columbia Gas will dispatch a technician to your address at no charge to investigate. Stay outside until the technician arrives and clears your home.

Other ways to contact Columbia Gas besides phone

Each state's Columbia Gas division has a website where you can pay your bill, report an outage, or submit a question through an online form. The website also shows current outages in your area and provides information about service requests. You can find your state's website by searching "Columbia Gas [your state]" or by looking at your bill, which lists the website address.

Some divisions offer text message alerts for outages and service updates. You can sign up for these on the website or by calling customer service. Email is not typically available for urgent issues, but many divisions accept non-urgent questions through their website contact form, with responses usually coming within one business day.

What to do if you cannot reach customer service

If you have been on hold for an extended time or the line keeps disconnecting, try calling during a different time of day. Early morning (7 a.m. to 9 a.m.) and mid-afternoon (2 p.m. to 4 p.m.) typically have shorter wait times than lunch hours or late afternoon. If you are calling about a billing question, you can also log into your online account to view your bill details, payment history, and usage.

If you have a complaint about service or billing that customer service has not resolved, ask the representative for the complaint department or file a complaint through your state's public utilities commission. Each state has a commission that oversees gas companies and can investigate disputes. The commission's contact information is usually available on the Columbia Gas website or by searching "[your state] public utilities commission."
