Localization means translating a text from the source language into the target language while also adapting its content, structure and/or style for a specific country, region, culture and/or social group.

The need for localization usually arises out of market differences (in distribution networks, product and accessories availability, target buyers, currencies, measurement units etc.), differences in legal requirements (such as warranty terms), cultural differences (relevant for product names, advertising slogans and strategies and the like) etc.
