In the class of stratified groups endowed with a left invariant Carnot-Carathéo\-dory distance, we give an algebraic characterization of purely unrectifiable groups and we study rigidity properties. The main feature of our approach is the use of a suitable area formula with respect to the Carnot-Carathéodory distance.

Keywords: Rectifiability, stratified groups, rigidity
