Electric Service Identifier (ESID) Lookup

If you live in Texas, you are a resident of one of the lucky 18 US states with energy choice. There are dozens of retail energy providers (REPs), offering Texas customers cheaper electric rates, residential and commercial plans, green energy options, and outstanding customer service. If you want to switch, you will need your ESI ID. Let’s look at what it is.

What is an ESI ID?

Your ESI ID — or “Electric Service Identifier”, also known as an ESIID, ESI ID, or ESI-ID is a unique identifier assigned to every electricity meter connected to a Texas home or a business. If you search for your ESI ID on your actual meter, you wouldn’t find it. You will however find it online, by entering your zip code and your residential or commercial address.

What information does it contain? Your ESI ID is simply the physical address where you receive your electricity. It allows the electricity company to verify your identity and lookup your electric bill history when switching electric plans.
