#maritime

The NGA World Port Index (WPI / Pub 150) as an API — 3,800+ maritime ports across 195 countries. Look up any port by its WPI number (e.g. 31140 → Rotterdam) or UN/LOCODE (e.g. NLRTM); search by name, country, harbor size or water body; or find every port within a radius of any coordinate (great-circle distance). Each record carries the UN/LOCODE, country, coordinates, harbor size and type, channel/anchorage/pier depths, maximum vessel length and draft, plus facility flags (container, oil/LNG terminal, ro-ro, dry dock, …). Ideal for shipping, logistics, maritime and supply-chain tools.

Search a database of 17,000+ seaports worldwide from UN/LOCODE. Find ports by name and country, look one up by its UN/LOCODE, or find all ports near a coordinate (radius search). Each record includes the UN/LOCODE, coordinates, country and connected transport modes (rail, road, airport) — ideal for shipping, freight, supply-chain and logistics applications.
