Moving to Missouri: utilities and your first-month checklist

Which company serves your new address depends on where in Missouri it is. Each link below goes to that company's own page for starting service. Start it two to three weeks ahead, from the day you get the keys.

Help with the bills

If deposits or bills are a stretch, Missouri runs energy assistance: official assistance page. Ask the utility about deposit waivers too; many waive the deposit with a good payment letter from your old company.

Problems with a utility

The Missouri Public Service Commission regulates utilities in Missouri and takes complaints.

Your first month in a new state

• USPS: change your address: Start mail forwarding up to 30 days early. The real site is usps.com.
• Your new state's motor vehicle office: Driver's license, registration and title. Most states set a short deadline after you move, so check yours first.
• Register to vote: Routes you to the official registration for the new state.
• Medicaid, if you have it: Medicaid doesn't move with you. You apply again in the new state.
• Health insurance: A permanent move can open a special enrollment period.
• Social Security: Change your address once here; Medicare gets it from Social Security.

Utility companies and service areas checked October 2026. Service areas follow addresses, not county lines exactly: confirm with the company before you book.
