ISO	3166-3

ISO 3166-3 is an international standard thatdefinesthe expired country code according to the ISO 3166-1 standard and is the third part of ISO 3166 .

If after 1974 states

• absorbed in another (for example the GDR in the Federal Republic of Germany )
• fell apart (for example Czechoslovakia )
• have changed their name (for example Upper Volta )

their abbreviations are deleted from ISO 3166-1 and added to ISO 3166-3 with two additional letters. The first two letters represent the original country code from ISO 3166-1 and the last two letters the new country code from ISO 3166-1. If there is no clear successor to the original country, the last two letters are HH. In the case of Serbia and Montenegro, which as a federal state had the abbreviation CS, CSXX was specified instead of CSHH in 2006, as CSHH had already been used for the former Czechoslovakia.

Examples:

• The German Democratic Republic (DD) joined the Federal Republic of Germany (DE), which ended its existence. Thus, in ISO 3166-3, the country code of the German Democratic Republic is DDDE.
• Czechoslovakia (CS) was divided into the Czech Republic (CZ) and the Slovak Republic (SK). Thus, in ISO 3166-3, the country code of Czechoslovakia is CSHH.
• Upper Volta (HV) renamed itself Burkina Faso (BF). Thus, in ISO 3166-3, the country code for Upper Volta is HVBF.

In databases with historical (mostly statistical) information, valid entries can be made again from the invalid keys by making appropriate changes. The original coding remains traceable and the current assignment (CS as CSHH or CSXX?) Becomes clear again.

Obsolete ISO 3166-1 alpha-2 codes

The following list contains all expired two-letter ISO 3166 country codes. Many of the abbreviations were replaced before the introduction of the Domain Name System so that they were never used as top level domains . The year of replacement is given for each abbreviation.

Leaking codes could be awarded according to current practice, after five years, as happened with AI, CS, GEand SK. However, since they have become considerably more durable thanks to Internet domains (for example as part of still valid e-mail addresses ), they are no longer to be reassigned.
