What is Country List

Last reviewed:

Country List is a searchable reference of ISO 3166-1 alpha-2 country codes paired with localised display names provided by the browser's Intl.DisplayNames API.

It's ideal for building dropdowns, validating form input, or quickly finding a country code by name.

Why use it

  • Pick ISO codes for forms and geolocation logic.
  • Validate user-provided country codes.
  • Convert country names to codes during imports.
  • Build multilingual country dropdowns.
  • Share a reference with non-technical teammates.

Features

  • ISO 3166-1 alpha-2 codes
  • Localised country names
  • Keyword filter
  • Alphabetical sort
  • Local-only Country List processing keeps data in-browser

How to use Country List

  1. Type a keyword. e.g. 'United', 'IN', 'Brazil'.
  2. Click Run. Matching countries and codes render.
  3. Copy entry. Use in your form, config, or spreadsheet.

Common errors

Using three-letter codes

ISO 3166-1 alpha-3 isn't shown here.

Fix: Use our dedicated alpha-2/3 converter if you need the longer form.

Localised names

Country names are English by default.

Fix: Browser locale can alter display names — set navigator.language if you need a different locale.
