ESI ID FAQs

What is an ESI ID?

In Texas, your ESI ID identifies the physical address where you get electricity. It’s a unique 15 or 22-digit number assigned to the electricity meter for your house, apartment, or business. If your property has more than one meter, you’ll have an ESI ID for each.


ESI IDs aren’t listed on meters. To find yours, search here or check on your electricity bill.

Why do you need an ESI ID?

What does inactive meter or no address found mean?

If your search for an ESI ID results in “Inactive Meter” or “No Address Found,” you’ll need to contact your local utility company.


An inactive meter means the ESI ID you searched is retired. In this case, you’ll need a new one assigned. “No Address Found” usually means you’re in a new building or ongoing construction. You will need to get your meter set, then eventually get a permanent meter.
