Our corporate hierarchy data shows the relationships between parent companies, subsidiaries, and shareholders, revealing control, structure, and potential risks within any corporate group. Whether you’re researching American Tower or any other global firm, this insight supports compliance checks, market analysis, and better CRM management. With verified ownership data covering over 380 million companies worldwide, CompanyData.com provides a clear picture of who owns what across borders and industries.

How American Tower's Global and Local Headquarters Are Mapped

At CompanyData.com, company profiles like American Tower are structured using a three-level hierarchy: Global, National, and Local headquarters. This system shows how individual entities fit within the entire corporate family.

Levels in our hierarchy system

  • Global Headquarters — The American Tower Corporation serves as the global headquarter, positioned above all other entities in the group. It directs global strategy and holds overall ownership. The global headquarter ID is 01080205969.
  • National Headquarters — These are country-specific divisions controlling operations locally and reporting to the global head office. American Tower has national-level entities in countries including the USA, India, Brazil, Mexico, and the UK among others.
  • Local Headquarters — These smaller offices supervise regional or site-specific operations, such as managing individual communication towers and infrastructure within their markets.

Each entity is assigned a unique identifier, enabling easy linkage of subsidiaries to parent companies and allowing integration into your business systems.

Understanding control

Control is based on ownership stakes. If a parent company owns more than 50% of another company, we classify that as a controlled subsidiary. Our data focuses on these majority control relationships to clearly outline corporate ownership structures. This method offers a transparent look at complicated networks like American Tower’s and can be applied to any multinational.

Why this is useful

This structure helps identify who actually makes decisions within the American Tower network, easing compliance efforts and supporting mergers, acquisitions, or risk assessments. With over 616 subsidiaries spread across 18 countries including large counts in the USA (507) and India (73), and others like Brazil (10), Mexico (4), and the UK (1), our platform brings clarity to American Tower’s extensive global presence.
