Each research surname listed on the Perth DPS site has a reference to the country, state and province in which it occurs.
The codes used to describe the locations were developed and used by the people behind the "Genealogical Research Directory" and the "Roots Surname Lists" and are a complex combination of the Chapman codes, the United States and Canadian postal codes, the three letter ISO codes for nations, and the Norwegian standard county codes.
This list is a decoding key for the place name abbreviations. It is arranged alphabetically in code order but the following countries are also subdivided into states or provinces, each of which have their own specific abbreviation.
