What is EN ISO 3166-3:2013 ?

EN ISO 3166-2:2013 is a widely recognized international standard that provides a standardized system for identifying the principal subdivisions of countries and their subdivisions. This system of coding is based on a hierarchical structure that enables the classification of a country's subdivisions based on administrative divisions.

Each code consists of three parts: the country code, a hyphen, and the subdivision code. For example, in the United States, the country code is "US," and the state of California has the corresponding subdivision code "CA." Together, they form the complete code "US-CA."

The main purpose of EN ISO 3166-2:2013 is to establish a consistent coding system that facilitates the exchange of data related to geographic subdivisions. This includes, but is not limited to, addresses, demographic information, and location-based services. By providing standardized codes, it ensures interoperability among different systems and minimizes errors associated with inconsistent or incompatible coding schemes.

Additionally, this standard enables efficient data management, as it allows the grouping and sorting of data based on geographical regions. It also aids in analyzing trends, patterns, and correlations at the regional or local level. This information, in turn, can support decision-making processes, policy formulation, resource allocation, and various other applications.

In conclusion, EN ISO 3166-2:2013 is an essential document for country subdivision coding, providing a standardized system for identifying and coding the subdivisions of countries. Its purpose is to establish a consistent coding system that facilitates the exchange of data related to geographic subdivisions, ensuring interoperability among different systems and minimizing errors associated with inconsistent or incompatible coding schemes.
