Why Your ESID Matters

Your ESID (Electric Service Identifier) is a unique 17-digit number assigned to your Texas electricity meter. This identifier is essential when switching providers, setting up new service, or comparing electricity plans in the deregulated Texas market.

Think of your ESID as your meter's "social security number" - it stays with your physical location regardless of which retail electricity provider you choose.

FAQ

What is an ESIID?

ESIID (Electric Service Identifier) is a unique 17-digit number assigned to every Texas electric meter. Also called ESID number, meter ID, or service identifier, it's required for electricity enrollment.

Where can I find my ESIID without lookup?

Check your electricity bill header, smart meter display, or contact your Transmission Utility (e.g. Oncor, CenterPoint). Our lookup tool is the fastest way.

Why do I need ESID to switch providers?

Texas requires ESID verification to confirm service address validity and meter ownership when changing electricity companies.

Does my ESID change?

Your ESID stays the same as long as you don't physically move your meter. Recheck if renovating or moving to a new unit.
