About

In high-stakes environments - fintech, supply chain logistics, and global systems integration - data precision is not a luxury; it is a constraint. The ISO Standards Extractor is engineered to serve as the definitive source of truth for geopolitical and financial identifiers.

This tool aggregates the three pillars of international data interchange:

ISO 3166-1: Defines codes for the names of countries, dependent territories, and special areas of geographical interest. It covers Alpha-2 (used for TLDs), Alpha-3 (machine-readable passports), and Numeric (UN Statistics).
ISO 4217: Establishes three-letter codes (e.g., USD, EUR) and numeric IDs for currencies, essential for SWIFT messaging and payment gateways.
ISO 639: Standardizes nomenclature for languages, critical for i18n (internationalization) and localization layers.

We solve the "Fragmented Data Problem." Instead of consulting three different Wikipedias or stale CSVs, this engine provides a unified, cross-referenced object model. It handles edge cases like the difference between Switzerland's numeric code (756) and its currency code (756), or the non-correlation in others (e.g., Germany 276 vs EUR 978).

Formulas

Validation of ISO standards often requires checksum verification or strict set membership. For a given input code c, validity is determined by its existence in the active registry S.

validate(c) =

{

TRUE if c ∈ ISO₃₁₆₆ ∪ ISO₄₂₁₇FALSE otherwise

When mapping currency precision (minor units), the relationship follows the exponent e defined in ISO 4217, where the smallest unit is 10^-e.

Value_base = Value_int × 10^-e

Frequently Asked Questions

Alpha-2 (2 letters) is the general-purpose code used for the internet (ccTLDs like .us, .fr) and postal systems. Alpha-3 (3 letters) is more closely related to the country name and is used when better visual distinction is needed, such as in machine-readable passports (MRTDs) and complex data mapping where a 2-letter collision might occur.

Calling codes are defined by the ITU (International Telecommunication Union), not ISO. Some codes encompass multiple ISO entities. For example, "+1" covers the North American Numbering Plan (NANP), which includes the US, Canada, and many Caribbean nations. This tool maps these shared codes to their respective specific ISO entities.

No. While they sometimes match coincidentally (e.g., USA is 840, USD is 840), they are distinct standards managed by different agencies. The Eurozone countries (Germany, France, etc.) have their own country codes but share the Euro currency code (978). Never assume a correlation in database architecture.

ISO 3166 is dynamic. Updates occur when countries change names, split, or merge (e.g., Türkiye, North Macedonia, Eswatini). ISO 4217 (Currencies) updates with re-denominations or new currency introductions. This tool's database represents the active snapshot of the registry.

Yes. The Alpha-2 country codes provided here are the first two characters of an IBAN (International Bank Account Number), and the ISO 4217 currency codes are the standard for SWIFT message payloads (Field 32A). This data is compliant with banking standards.
