Knowing who owns which part of a company is important to understand how it works globally. Our corporate hierarchy data shows the links between parent companies and their subsidiaries, making it easier to see control, structure, and risks in any corporate group. For multinational firms like BT Group, this data is useful for compliance, market research, and data management. CompanyData.com offers verified ownership records on over 380 million companies worldwide, giving a clear picture of company relationships across borders and sectors.
CompanyData.com classifies companies using a three-level system: Global headquarters, National headquarters, and Local headquarters. This shows how a company’s different parts connect to each other.
Every company entity has its own unique ID to link it to others, making the ownership structure clear and easy to analyze.
Control depends on ownership stake. If a company owns over 50% of another, it’s a controlled subsidiary. Our data focuses on these majority-owned companies to clearly show how global groups like BT are made up.
This view reveals who really makes decisions in BT Group, helps with compliance checks, and supports risk or market analysis. CompanyData.com has data on millions of companies in over 200 countries, giving teams a clear view of BT’s global corporate setup.
