Identifying the owner of an aircraft in 2026 is a straightforward process using the plane's tail number (registration number), which is prominently displayed on the fuselage. For U.S.-registered aircraft (numbers beginning with "N"), you can use the FAA Aircraft Registry Inquiry database available online. By entering the tail number, you can instantly see the registered owner's name, address, the aircraft's manufacturer, and its airworthiness status. For international aircraft, sites like FlightAware, Flightradar24, and Airfleets.net provide extensive ownership and operator data. It is important to note that many private jets are owned by "Trusts" (such as Bank of Utah Trustee) or shell companies to maintain the actual owner's privacy. If an aircraft is leased, the registry will often show the leasing company (the legal owner) rather than the airline currently operating the flight. For those needing deeper records for legal or historical research, the International Civil Aviation Organization (ICAO) maintains records, and specialized services like JetNet or AMSTAT provide highly detailed corporate ownership histories for a subscription fee.
