About Corporate Overview

ADTRAN, Inc. is a leading global provider of networking and communications equipment. Headquartered in Huntsville, Alabama, with sales offices strategically located throughout the United States and around the world, our mission is to be a trusted provider of global communications solutions, to develop innovative technologies used to create products and services that make communications simpler and more affordable for people everywhere, and to foster an entrepreneurial environment supported by enthusiastic employees who exhibit an unwavering commitment to personal integrity and support our customers beyond their expectations.

Incorporated in 1985, ADTRAN began operations in 1986 following AT&T’s divestiture of the Regional Bell Operating Companies (RBOCs). This created an opportunity for companies like ADTRAN to supply network equipment to the seven RBOCs as well as the more than 1,300 independent telephone companies in the United States. From a humble beginning with only seven employees, ADTRAN has grown into a global leader in telecommunications with more than 2,000 employees. Likewise, the company serves a diverse customer base that spans more than 68 countries.

With products for both carrier and enterprise markets, the company is uniquely positioned to provide complete end-to-end solutions that produce the greatest network efficiency and at the lowest possible cost. Service providers depend on ADTRAN equipment to connect central offices or remote terminals directly to subscriber equipment, thus enabling the delivery of voice, video and Internet services, ADTRAN also supports business customers with a full line of business-class networking solutions.

With the demand for bandwidth increasing at phenomenal rates, ADTRAN is at the forefront of the development of new technologies that will enable service providers to glean more bandwidth from their existing infrastructure as well as new virtualized technologies that will pave the way for greater network scale and efficiency, enabling new services to reach more customers faster than ever before.


ADTRAN is committed to sustainability and has embraced the move to green technology wherever possible. We also promote sustainability efforts on each of our business locations and local communities.


ADTRAN takes an active role in the communities in which we do business through employee volunteer efforts and corporate sponsorships and donations. The company strives to be a good corporate citizen and promote community involvement among its employees.
