How We Outline AT&T’s Global, National, and Regional Headquarters

At CompanyData.com, the corporate structure of a company like AT&T is represented using a three-level model: Global, National, and Local headquarters. This framework shows how each entity is part of the larger corporate family.

The three levels explained

  • Global Headquarter — AT&T Inc., headquartered in Dallas, United States, acts as the global headquarter for its entire group, sitting at the top of the hierarchy.
  • National Headquarters — These manage operations within a country and report directly to the global headquarter. Examples include AT&T Canada, AT&T Mexico, and AT&T United Kingdom.
  • Local Headquarters — Local level subsidiaries manage divisions or business areas within regions or cities, ensuring regulatory compliance and operational oversight.

Each company entity carries a unique ID, enabling detailed connections between subsidiaries and parent companies, letting users trace control and ownership paths seamlessly.

How control relationships work

Ownership control is identified when a parent company holds more than fifty percent of a subsidiary’s shares. Our data emphasizes such majority-controlled subsidiaries to give a clear picture of the corporate hierarchy. This method reveals AT&T’s complex ownership network and can be applied to any large multinational corporation.

Why this view is essential

By mapping entities with validated ownership details, CompanyData.com empowers users worldwide to navigate AT&T’s corporate family with ease.
