ISO 3166:1974 was first published in 1974. It was descended from the distinguishing signs for vehicles under the Conventions on Road Trafficof 1949 and 1968. It has been modified as needed over the years, and updated with new editions in 1981, 1988, and 1993. One source says thatthe three-digit codes first appeared in the 1981 edition. In 1996, it was announced that the standard would be divided into three parts. ISO3166-1 would continue to provide two-letter, three-letter, and three-digit codes for countries. ISO 3166-2 would contain codes for primaryadministrative subdivisions of countries. ISO 3166-3 would provide codes for obsolete country names (those deleted from ISO 3166 since 1974).The first publication of ISO 3166-1 was dated 1997.
The following timeline lists all the changes I could find that have affected the names or the codes for any entity. In most cases I haven'tmentioned the code values following a change, because they can be looked up in theCountry Codes table, or sometimesfarther down the timeline.
