Find My Electric Company: Who Serves Your ZIP or County

Every year, utilities tell EIA which counties they serve. The tool reads that service territory table and lists the utilities for the county you choose, largest first by residential customers. It shows the type of utility so you can tell an investor-owned company from a cooperative or a city system.

County is the finest level the federal table offers. It does not follow city limits, neighborhoods or individual streets, so two houses in one county can have different utilities.

• Investor-owned. A private company regulated by the state. These serve the most households.
• Municipal. A city or town runs the electric system and often the water service too.
• Cooperative. A nonprofit owned by its members, common in rural areas.
• Public power district. A public body that is not a city, found in several western and plains states.

1. Check the top of your latest bill. The company name and logo are there.
2. If you have no bill, look at your meter. Many meters carry the utility name.
3. Ask your landlord, your property manager or a neighbor on the same street.
4. Call your city or county office and ask who provides electric service at your address.
