I'm looking to create directory and I would like to know what standards are available for classifying businesses, professions, and organizations?
Two standards are big in the USA, but there may be many others
- North American Industry Classification System (NAICS)
- Standard Industrial Classification (SIC) (older US standard)
You can read about these two standards here.
Also, internationally there is the International Standard Industrial Classification of All Economic Activities (ISIC) a production by the United Nations. This has the advantage of being internationlized (available in other langauges). You can find ISIC for download here.
Also see the other nation-specific standards,
- Australian and New Zealand Standard Industrial Classification (ANZSIC)
- Nomenclature of Economic Activities (NACE) (a subset of ISIC with further divisions for "European Economies")
- Japanese Industrial Standards Committee (JSIC)
