Case Study: Postal Services Sint Maarten achieves universal postal access and improved delivery efficiency with what3words

An island addressed with what3words and Postal Services Sint Maarten

what3words has partnered with Postal Services Sint Maarten (PSSNV) to provide universal 3‑word addresses across the island. Sint Maarten — the third country and third continent to adopt the system — faces patchy or duplicate addressing and rapid development that traditional systems have failed to keep up with.

By assigning every location a unique three‑word address (for example overlays.campfire.sometime or music.crunchy.electing) and integrating it into PSSNV’s infrastructure, deliveries and mail services become more efficient and accessible. The change aims to reduce customer frustration, improve operational efficiency, and support the island’s economic growth and social development.
