Since 1955, Uniworld Online has been the most trusted source for contact information of multinational companies. For decades, we published two directories: American Firms Operating in Foreign Countries and Foreign Firms Operating in the United States. In 2015, we merged these directories into one online, searchable database, Uniworld Online, that covers multinational companies with headquarters in over 200 Countries and 20,000 industries.

When sourcing, building your business, selling, tracking competitors, or seeking employment with a multinational firm, Uniworld Online helps unravel the maze of "who operates where" and “who owns whom.” Uniworld Online provides contact information for headquarters, subsidiaries, branches and executives of multinational firms. (Companies solely operating domestically are not included.)
