Where Is the Tor Project Headquartered?

The Tor Project is legally registered as a 501(c)(3) research and education nonprofit organization based in the United States, with its legal headquarters located in Seattle, Washington. While the organization maintains a physical mailing address and legal incorporation in Washington state, its operations and core team function primarily through a decentralized, remote workforce distributed worldwide.

The Tor Project, Inc. is formally incorporated in the United States under section 501(c)(3) of the Internal Revenue Code. Its official legal and administrative headquarters is situated in Seattle, Washington. This nonprofit status allows the organization to receive tax-deductible donations, government research grants, and foundational funding to develop and maintain free and open-source privacy software.

Organizational History and Relocation

The organization was officially founded in December 2006 by computer scientists Roger Dingledine, Nick Mathewson, and several others. In its early years, the Tor Project was legally based in Cambridge, Massachusetts, near the Massachusetts Institute of Technology (MIT), where much of the early research and development for onion routing took place. Over time, the administrative and legal base was transitioned to Seattle, Washington.

Distributed Operational Model

Despite its legal domicile in Washington state, the Tor Project does not operate as a traditional centralized corporation. The vast majority of its paid staff, contractors, and core developers work remotely across dozens of countries. Furthermore, the physical infrastructure of the Tor network itself is operated independently by thousands of volunteer-run relays located across the globe, completely separate from the legal headquarters of the organization.
