ISO code formats

Alpha-2 — two letters (e.g. US). Common in locales, domains, and APIs.
Alpha-3 — three letters (e.g. USA). Often used in sports and some trade systems.
Numeric — three digits (e.g. 840). UN M49 codes; remain stable if names change.

Data class: Third-party open reference data assembled for tools — not an official ISO, UN, or national-statistics publication.

Data limitations

Not an official ISO, UN, or national-statistics publication.
Population and area are reference estimates with effective year where known.
Postal checker validates format only — not delivery-point existence.
Currency finder does not show live FX rates (see Currency Converter for rates).
Driving side / measurement may be incomplete for some territories.
Administrative divisions are not bulk-published (avoids thin/incomplete geography pages).
Timezone “now” depends on server/OS tzdata freshness.
ODbL sources require attribution and share-alike considerations for redistributed database dumps.

Important distinctions

Alpha-2 vs alpha-3: ISO alpha-2 and alpha-3 are different country-code formats (for example PK vs PAK). Numeric codes (for example 586) are a third, digit-based form.
Not a calling-code tool: Telephone dialing prefixes such as +92 belong on the Calling Code Finder, not this ISO converter.

Frequently asked questions

What is the difference between a country calling code and an ISO country code?

ISO codes identify countries in data standards (PK / PAK / 586). Calling codes are telephone dialing prefixes (+92). This converter handles ISO codes only.

What is the difference between alpha-2, alpha-3, and numeric?

ISO alpha-2 and alpha-3 are different country-code formats. Alpha-2 (e.g. PK) is two letters; alpha-3 (e.g. PAK) is three letters; numeric (e.g. 586) is a three-digit UN M49 code.

What if my code is unknown?

We only resolve officially assigned codes present in the catalog. Typos, obsolete codes, and user-assigned ranges are rejected with suggestions when a close country name match exists.
