How Aircraft Tail Numbers Work
The Chicago Convention & ICAO
Under Article 20 of the Convention on International Civil Aviation (1944), every aircraft engaged in international air navigation must display nationality and registration marks. Nationality prefixes are assigned by the ITU (International Telecommunication Union) and ratified by ICAO.
Offshore & Flag-of-Convenience Registries
Aviation leasing firms and corporate jet owners frequently register airframes in specialized jurisdictions such as Bermuda (VP-B, VQ-B), Ireland (EI-, EJ-), Isle of Man (M-), or Guernsey (2-), which offer favorable tax treaties, English common law asset protection, and standardized airworthiness certificates.
Custom & Sequential Vanity Tails
Airlines often reserve custom letter combinations that reflect their brand or fleet sequence. For example, British Airways registers aircraft with tail suffixes ending in "BA" (e.g., G-XWBA), while Singapore Airlines long-haul widebodies frequently carry "SK" suffixes (e.g., 9V-SKA).
