Zip Codes

The listings below represent all zip codes currently within Oncor’s service territory including zip + 4. However, some zip codes include geographic areas that are multiple certificated with Cooperatives and Municipally Owned Utilities and not solely dedicated to Oncor. It is also important to note that zip codes are subject to jurisdictional review by local governing municipalities and periodically may change.

Also included on these Zip code lists are columns indicating the number of meters that have been changed to advanced meters, the total number of meters the company serves in the zip code and the percent completion as part of our ongoing commitment to let the market know the status of Oncor’s Advance Meter Project.
