Well, I just know something that I have read it a lot but I don't know the meaning, i18 (Internationalization) and l10n (Localization). The abbreviation is pretty cryptic for me. For now, I'm going to explain what I have learn something from this abbreviation.

  • i18n = Internationalization: i, then 18 letters, then n
  • l10n = Localization: l, then 10 letters, then n

What is it?


Internationalization is a process to make a product or an application "international"; that is to support any language or local configuration. It usually needs the developer to change something in the product or application.


The internationalization approach adopted by McDonald’s is in line with the company’s franchising approach to expansion.

In software development, the internationalization approached by providing some configuration to support characters or font, to define a timezone, unit, and the other things.

Ubuntu provide an interface for translator to localize the Ubuntu program interface — Translations: Ubuntu.


Localization is a process to make a product or and application "localized"; that is, work for a given local and concrete context, adapted to the user. Localization only needs to fill the container that has been created from internationalization process. Localization process are not involving the developer (except in some cases).


You can think on McDonalds in (most of) Asia, they had rice to localize their menu with local food.

While in software development, there's translator that can do translation, adjustment, and the other things to localize the application.

You can help to translate Ubuntu program interface to Indonesian — Indonesian (id) : Bionic (18.04) : Translations : Ubuntu.
