Texas Telephone Product Showcase
The Texas Telephone Association, Inc., (TTA) was founded in 1905. TTA is the trade association that supports the incumbent local exchange telephone companies of Texas. Come join us!
The incumbent local exchange telephone companies-or ILECs-are the original wire-line telephone companies. They are the primary service providers to the residents and business communities of Texas. There are 54 incumbent local exchange telephone companies–large and small–providing local exchange service to more than 13 million access lines in 1,244 exchanges across Texas . The majority of our member companies serve fewer than 5,000 customers each, and more than one-third of these companies are member-owned telephone cooperatives. Learn more.
