Fair Wear Foundation works with companies from seven European countries. These companies buy their products from factories in fifty-five countries. Fair Wear Foundation, however, is not active in all of these countries. Countries where FWF affiliates have production, but where FWF is not active, are grey on this map.

Most of FWF's work is focused on four priority countries: Bangladesh, China, India and Turkey. Around 80% of FWF member production comes from these four countries.
