Texas ESID Look Up

  • An Electric Service Identifier (ESI ID) is a unique number that identifies each electrical service location in Texas.
  • The ESI ID is tied to the physical property address and remains constant, even when customers or utility companies change.
  • This identifier is separate from your utility account number and meter number – you won’t find it displayed on your electric meter.

Your Electric Service Identifier (ESID) is a 17 to 22-digit identification number assigned to your address. This unique number is similar to a social security number for your home’s energy usage. Retail electricity providers (REPs) use the ESID to track your home’s electricity usage history and billing information. With over 12 million homes in Texas, accurate electricity usage tracking is paramount. You’ll need your ESID number when setting up electricity service, switching providers or moving homes in Texas. You can find your home’s ESID number using the tool below. Simply punch in your address, and the Find My ESID tool will pull the ESID number for your address.

What Is an ESID Number?

An ESID (also written as ESI ID or ESIID) is a unique identifier that helps your utility company and electricity company identify and track your usage for accurate billing. It connects to your electric meter, ensuring the company accurately tracks every kilowatt-hour (kWh) used by the correct address. While your account number or electricity company may change, your ESID stays the same as long as you have the same service address. This consistency helps prevent mix-ups or billing issues. However, the ESID is not tied to you personally; it’s associated with your address. You’ll get a new identification number if you move homes.

Why Do I Need My ESID Number?

Your ESID number helps your transmission and distribution utility (TDU) and electricity service provider accurately charge based on your energy usage. Since it’s tied to your meter, the ESID ensures you only pay for what you use, preventing overcharging or undercharging. It also plays a key role in making transitions smoother in Texas’ deregulated energy market, where you have the power to choose your electricity provider. Here are a few situations where you’ll need your ESID:

  • Setting up new electricity service: Your new provider will need your ESID to set up electricity service. It identifies your home and ensures accurate billing for your usage.
  • Moving homes: You’ll need to find the ESID of your new address to set up electricity when moving homes in Texas. You can stay with your current provider (if it offers service in your new area) or switch energy companies. Either way, you’ll need the ESID of your new home to sign up for service and track your energy usage.
  • Switching electricity providers: Knowing your ESID ensures a smooth transition when changing providers, helping prevent billing issues and service interruptions.
  • Power outages: In case of power outages or emergencies, your ESID allows utility workers to quickly locate your home and address the issue more efficiently.

Texans who reside in deregulated areas of the Lone Star State can compare energy rates and electricity plans to secure lower total energy costs. However, energy pricing in Texas varies based on your electric utility service location. Always be sure to shop by ZIP code to see plans in your area. Having your ESI ID handy can be handy when you’re comparing electricity rates and energy plans in your Texas neighborhood because you’ll have the info you need when you’re ready to enroll in a new plan.

Common Questions About ESID Lookup

The ESID lookup didn’t find my address. What should I do now?

ESID lookup tools work for active meters, so new construction or recently built homes might not have an ESID yet. Contact your local utility company to request and set up an ESID for your home.

What if I’m moving to a new address?

Your ESID matches a physical address and isn’t tied to you personally. When you move homes, your new address will have a different ESID. Contact your utility company or use online lookup tools to determine the ESID of your new address.

Can I Find an ESID for a Commercial Property?

You can find commercial ESIDs the same way you’d find residential ESIDs. Your electricity bill, online account or utility’s customer service lists the identification number. For active meters, you can use online ESID lookup tools to determine your ID number.

What is the difference between an ESID and a meter number?

A meter number identifies your electric meter and tracks your usage. An ESID identifies your address and stays with it, even if you change meters or energy providers. While the ESID is linked to your meter, the meter number may change if you have a new meter installed.

Do I need my ESID to switch providers?

Yes, you’ll need your ESID to switch providers. It helps your new provider identify your address and correctly set up your account. Having your ESID ready smooths the transition and helps prevent power disruptions during the switch.

How many digits are in an ESID?

Each utility assigns ID numbers in a specific way, but they are typically 17 to 22 digits long. Oncor, AEP Texas and TNMP have 17-digit ESIDs, while CenterPoint’s are 22 digits long.

Is my ESID confidential information?

No, your ESID isn’t confidential. Anyone can look up your address and determine your ESID with an online lookup tool. While the ESID isn’t private, you should still protect it to prevent unauthorized access to your electricity account. Only share your ESID with trusted entities that need the information, such as your energy provider.
