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?

Doing anything with your electricity requires an ESI ID. If you live in a deregulated market, you’ll need the ESI ID to find retail providers in your area, shop renewable plans, enroll in new service, or even ask for a new meter.

Where is the ESI ID on your bill?

You can typically find your ESI ID on your electricity bill listed under your account number. Check out this blog post for examples and more information.

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.
