What Is an ESID Number?

An ESID (Electric Service Identifier) is a unique number tied to every electric meter in deregulated parts of Texas. Think of it as a fingerprint for your service location. It connects your property to the grid and tells energy providers exactly where to set up or switch service.

Every ESID begins with the digits 10, followed by a code that identifies your local utility, and then a unique number for your specific location. Your ESID stays with the address, not with you, so it does not change when you switch retail electric providers.

Where to Find Your ESID

Your ESID appears on your electricity bill, usually near your account details. You can also look it up by address using the tool above. If you are setting up service at a new location and do not have a bill yet, the lookup tool is the fastest way to find it.

Every Texas ESID follows the same format. The first two digits are always 10, the electric industry prefix. The next five digits are the TDSP ID, which identifies your local utility, so those five numbers tell you who delivers power to your address. The remaining digits are a unique ID for your specific service location.

The lookup tool shows active and de-energized service locations. If an address does not appear, the meter may be new and not yet assigned, or the location may be in a regulated area that is not part of the deregulated market.

An inactive status means the meter has not been set up yet, or the power is not currently on at the location. This is common when moving into a new home or relocating your business. Contact our team so we can help you get your service set up.

Yes, the two terms describe the same situation: a valid service location where power is not currently flowing. You may see either word depending on the source. It is common for vacant properties, new locations, or spaces between tenants. The ESID stays valid, so service can be restored without assigning a new one.

No. The meter number identifies the physical device measuring your usage. The ESID identifies the service location itself. They are different numbers with different purposes.

No. Your ESID is tied to the address, not to your provider or account. You keep the same ESID no matter which retail electric provider you choose.
