What's my ESID Number?
Your ESID Number (pronounced "Easy I.D."), is your Electric Service Identifier. It is a unique number to your property address. It helps the utility companies easily enroll customers, switch energy providers, and meter your usage. It is sometimes referred to as an ESIID, ESI ID or ESI-ID.
It essentially acts as a social security number for your electric meter.
While it's not actually visible on your meter you can our free ESID lookup at the top of the page to find yours.
Both commercial and residential meters have an ESID. When you use our tool you can see what utility company services your location as well as other important information.
Your ESID number is helpful when you are shopping for electricity plans in Texas. Your energy provider will use this number to set up the electricity service to your meter.
The ESID for your meter will tell you which utility company (ex: Oncor or Centerpoint) is responsible for the delivery of electric service to your property.
Since rates are dependent on your location, the ESID number allows you to get accurate pricing information for your home or commercial location.
While you can't select your utility because it is determined by your location (ex: Oncor), you can select your Retail Electric Provider (REP). REPs are often called energy suppliers for ex: TXU and Direct Energy.
Your ESID is simply a unique number to help utilities and energy providers to enroll you in energy plans and meter your usage. Learn more about reading your electric meter here.
Our commercial ESID lookup tool at the top of the page is able to identify ESID numbers for both residential and business addresses.
If you are interested in finding lower commercial electricity rates, we recommend you enter your zip code and compare business energy providers here.
