Country Information

ISO Country Code Converter

Convert between ISO 3166-1 alpha-2 (PK), alpha-3 (PAK), and numeric (586) codes. ISO alpha-2 and alpha-3 are different country-code formats. This tool does not convert telephone calling codes.

Suggestions

ISO code formats

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

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.
