FF Dax is a humanist sans-serif typeface designed by Hans Reichel, published by FontFont library.

The UPS Sans typeface, used in most of United Parcel Service branding since 2003, is a modified version of FF Dax.

Wm Morrison, the British supermarket chain uses FF Dax on most in-store promotional material, hanging product location signs, and points of interest around the store – such as special offers and two-for-one deals.

The typeface was adopted in the United Kingdom by David Cameron in 2005 as part of the branding for his campaign for leadership of the Conservative Party.

FF Dax is also the corporate typeface of Finnish transportation company, VR Group and is used in its publications and on its website.
