TS ISO 3166-2

TS ISO 3166-2 is a coding standard for identifying the subdivisions of countries, covering the general framework used to represent administrative units such as states, provinces, regions, cantons, and similar territorial divisions. Such codes reduce variation in how place names are written and help create consistency in data exchange. This record is for a standard listing; because the official scope text is unavailable, the description below explains the general technical subject and well-established use of this coding system.

Purpose and structure of subdivision codes

The ISO 3166-2 family extends country coding by adding a subdivision identifier for internal territorial units of a country. In general, the code combines a country identifier with an additional element that points to a specific subdivision, making it easier to manage places with the same name, different spellings, or multilingual naming practices. These codes are commonly used as reference data in databases, logistics systems, public records, mapping applications, and communication systems.

What this kind of standard helps organise

• Brings regional names written in different languages or spellings under one shared reference.
• Supports short, machine-readable identifiers for internal administrative units.
• Helps produce consistent records in address, statistics, trade, and geographic information systems.
• Makes it easier to manage regional renaming and local name variants in a structured way.

Standards of this type separate naming from identification: instead of repeating the full local name every time, systems can use a stable code. This improves interoperability between datasets, while the actual administrative structure and local usage still depend on the official definitions of each country. For the exact clause structure, specific code lists, and current country-to-subdivision mappings, the published official text should be consulted.
