We are Spire. And we’re glad you’re here.

Things look new around here, and with our new look comes a whole new level of service. Because serving you is what we do. We’ll continue to take care of your natural gas and energy needs so you can focus on what matters most.

I already have an account

New customers

I’m ready to start service at a new home or business.

I just want to pay my bill

You got it. We offer several ways to pay your bill - online or off.


We’re here to answer your questions.
Do I have to re-register my account?

Part of becoming Spire means giving you the tools to make your life easier – like a revamped website full of new features. Your old account number is still the same, but now you can manage your account from your phone, sign up for text and email alerts, sign up for convenient services like budget billing, schedule service appointments and more. Simply register your account to unlock these new features.

What happens if I don’t register with Spire?

We’d love for you to register your account online with us. But we understand if you want to pay another way. We have plenty of online and offline payment options that will work for you.

Can I still mail my bill to the same place?

Of course. If you wish to pay your Spire bill by mail:


PO Box 2224

Birmingham, AL 35246-0022

Do I have to re-enroll in Auto Pay or e-bill?

All your previously scheduled automatic payments, e-bill and budget billing program enrollments, payment arrangements and billing and usage history will still be available in your new Spire account – but with a new look and feel.

Is your phone number still the same?

Our phone number is still the same. To report a gas emergency, make a payment over the phone or speak to a member of our team about your account, contact us.

Why did Alagasco change its name?

We’re still the same company — just serving you with a whole new energy. Our growing company now serves homes in Alabama, Mississippi and Missouri, so we've changed our name to better reflect the company we're becoming. See what else is new.
