In France, "courrier express" refers to premium, time‑critical postal services offered by La Poste (e.g., Chronopost) or private couriers. The adjective "express" is borrowed from English but is fully integrated into French and often follows the noun, a pattern you’ll see with other nouns like "train express" or "service express".
