ESI ID

What is an ESI ID, and how do I find mine?

An ESI ID is the number that identifies the electric meter at your address. You can look yours up below by typing your address.

Published 13 October 2026

We search the public list of meters that ERCOT publishes. It covers homes in the parts of Texas where you can choose a provider.

Live in an apartment? Pick your building from the list and then your unit, or just type your apartment number.

What is the number?

ESI ID is short for Electric Service Identifier. ERCOT, which runs the Texas power grid, uses it to keep track of every meter.

The number belongs to the address, not to you. When you move out, it stays with the home.

Is it the same as my meter number?

No. Your meter number is printed on the meter itself. The ESI ID is the number on your bill that identifies your address in ERCOT's records.

Where is it on your bill?

Texas rules say every bill must show it. Look near your service address and account number.

It is a long number, so copy it exactly, digit by digit.

Can't find it with the lookup?

A brand-new home may not be on the list yet. Ask your landlord, the seller or the property manager.

Your local utility can help too. That is the company that owns the poles and wires, like Oncor or CenterPoint.

When do you need it?

You may need it when you start service at a new home, so the right meter gets turned on.

You also need it to set up Smart Meter Texas, a site that shows how much power your home uses.

1. Look it up

   Type your address above, or check your bill near the account number.

2. Copy every digit

   One wrong digit points to the wrong meter.

3. Bring your usage too

   With it, we estimate what each plan would cost your home.

Articles are general information for Texas electricity shoppers. Every cost Power Rate Check shows is an estimate, and the Electricity Facts Label is the provider's official price document — read it before you sign.
