European Union (27 countries)

Every EU member has a national adaptation of NACE Rev 2 - structurally identical (all 996 codes) with the national name. All share:

Shared System	Purpose
NACE Rev 2	Industry classification
EU NUTS 2021	Geographic regions
CN 2024	Combined Nomenclature for trade
ESCO	Occupations and skills
EU Taxonomy	Sustainable activities

Latin America

Most countries use CIIU Rev 4 - the Spanish-language ISIC adaptation. Colombia, Argentina, Chile, Peru, Ecuador, Bolivia, Venezuela, Costa Rica, Guatemala, and Panama all have CIIU variants. Codes identical to ISIC; labels in Spanish.

Sub-Saharan Africa

30+ countries adopt ISIC Rev 4 directly: Nigeria, Kenya, Ethiopia, Tanzania, Ghana, Senegal, and more. Sometimes with a national name, always the same 766 codes.

Asia-Pacific

The most diverse region:

Country	System	Codes
China	GB/T 4754-2017	118
South Korea	KSIC 2017	108
Japan	JSIC 2013	20
Singapore	SSIC 2020	21
Indonesia	KBLI 2020	766
India	NIC 2008	2,070
Australia/NZ	ANZSIC 2006	825

Middle East

Saudi Arabia, UAE, Oman, Qatar, Bahrain, and Kuwait all use ISIC Rev 4 adaptations.

Use cases

Use Case	What You Need	How the Profile Helps
Market entry	Which codes to register with	Official tier tells you the required system
Cross-border reporting	One internal code, translated per jurisdiction	Translation API + country profile per market
Data harmonization	Partners in different countries using different systems	Identify systems, then translate to common framework
Compliance mapping	Which regulations apply where	Regulatory systems included per jurisdiction

If you operate in 10 countries and need to report industry data for each, the country profiles tell you which system to use where. Combined with the translation API, you can maintain one internal code and translate to the local system for each jurisdiction.

World map

The country dashboard includes an interactive world map showing coverage by country. Color intensity indicates the number of applicable classification systems - from a handful in small island nations to dozens in major economies.
