How do I find which Indiana utility serves a specific address or ZIP code?
tou.tools maps 202 Indiana ZIP codes to the utilities that serve them. Because service territories can overlap, a ZIP may return more than one candidate utility; supplying a full street address resolves it to a single utility via a geocoded point-in-territory lookup. The REST API and MCP server both return the matching utility and its current TOU period.
