Case Study: Carteiro Amigo achieves reliable door-to-door deliveries in Rocinha with what3words

Carteiro Amigo - Customer Case Study

what3words partnered with local co-operative Carteiro Amigo to tackle the biggest addressing problem in Rocinha, Rio de Janeiro — a dense maze of tiny streets with no reliable addressing system. The lack of precise addresses made deliveries slow, costly, and kept residents from accessing services like banking, voting registration and online shopping.

Using the what3words app (which works offline on basic smartphones), Carteiro Amigo assigns simple three-word addresses, prints them on stickers, and organizes deliveries by district and station. This solution speeds up route planning, reduces training time for couriers, allows the co-op to scale, and ensures residents receive mail and online purchases directly at their door.
