This list contains all known International Registration Prefixes for aircraft, sorted by Country Prefix (Code)

The information in this list was colected from various books and publications, and many additional information was received from Rudi Longueville from Belgium, who's e-mail address I don't have, and Jos Stevens from Amsterdam, the Netherlands, who's e-mail address is: (stevens@nlr.nl).

Pascal Brugier has a very complete list of registration prefixes available on the web (in French) at w3.teaser.fr/~pbrugier, and even has additionally very many registrations (in zipped text files) for anyone to download.


Explanations and conventions:
=============================

Code           = International Registration Prefix, as displayed on the 
----             aircraft, but with letters from the Latin alphabet;
                 (Cyrillic or other alphabets are indicated in {} in the 
                  Description); 

Country        = English representation of the name of the Contry;
-------          (it is indicated, when the government form, like Republic, 
                  etc., is part of the name);
                 (previous names are listed as 'was OldName');
                 (equivalent and some indegious spellings/names are listed as
                  'also OtherName/Spelling');
                 (prevoius country affiliations are indicated by 'FROM - 
                  TILL OldName');
                 (Common International Abbreviations are also listed);

Description    = Displays and explaines (if available) all the possible 
-----------      registrations in the form '1 - 999, AAA - ZZZ'; meaning a
                 registration could be either a number between 1 and 999,
                 but without leading zeros, or any combination of three 
                 letters like AAA, AAB, AAC, up to ZZZ;
                 (if letter have a known special meaning, this meaning is
                  explained);

Current        = Y - (Yes) if the code is currently in use;
-------          N - (No) if the code is now out of use, either replaced by
                     another code, or the country ceased to exist;
                 ? - (Unknown) if it is not sure if this code was ever used
                     or ever assigned to this country;

Time-Frame     = Lists the time frame of the validity of this code, form of 
----------       registration or existence of country;
                 (a '(+)' denotes 'at least', a '(?)' denotes 'guessed');

CAPITALS       = in Code: as is (the registration prefix);
                 in Description: represents a range; "AAA - ZZZ" means:
                 possible registrations are AAA, AAB, etc. up to ZZZ;

the letter 'x' = represents a variable; possible values can be found in 
                 remarks like: (x = A/B/C); 

the '-' (dash) = after a Code: ("XX-"): represents the separator, as it is
                 displayed on the aircraft;
                 in Description: ("XXX - XXX"): means a range (from - to)

text in ()     = surrounds explanations or remarks;

text in []     = surrounds optional parts of registrations, which are 
                 either sometimes omitted or which are only sometimes used 
                 as modifiers;

text in {}     = represents letter from the cyrillic or other alphabets; 
                 it contains a visual representation of the character, 
                 using other ASCII characters (as far as possible);
