The International Register of Civil Aircraft is published jointly by Bureau Veritas (France), the UK Civil Aviation Authority and the ENAC of Italy, in co-operation with ICAO. The database, which contains information from over 45 countries and over 400,000 aircraft, is available on the internet by subscription from The International Register. A demo version of the database is available at this site, as are full details of the subscription rates which are based on the length of time access is required and the number of users.

The information on each aircraft varies depending on information supplied by the country of registration. Standardised descriptions of aircraft allows for consistent searching across the database irrespective of how the individual aircraft is described on a given national register. The standardisation is based on the International Aircraft Categorisation and Identification Standard (IACIS) compiled by the CAST/ICAO Common Taxonomy Team (CICTT)
