About this data
Port Register Guide
Portledger is a register of 5,000+ port and terminal locations compiled from the NGA World Port Index (Publication 150, 2019 edition), cross-referenced against the UN/LOCODE registry, with UN/LOCODEs, coordinates, harbor size, and recorded depth soundings (channel, anchorage, cargo pier, oil terminal) and tidal range for each entry.
How to Use It:
Use the top search box ("Search port, locality, country, UN/LOCODE…") to jump straight to a specific port by name or code.
Open the sidebar (menu icon, top-left) to filter by continent tag or by ticking individual countries in the country list; use "Filter country list…" to find a country fast, and "Major ports only" to hide small/unclassified anchorages.
Switch between the three views with the tabs: Map (interactive vector world map, scroll/pinch to zoom, drag to pan, ports cluster at low zoom), Grid (sortable table), and Compare (side-by-side port comparison).
In Grid view, click any column header (Port name, Country, UN/LOCODE, Harbor size, Channel depth, Cargo pier depth, Tidal range, Lat, Lon) to sort by that field; use "⬇ Export CSV" or "⬇ Export GeoJSON" to pull the filtered results into other tools.
Click any port (a map dot or a grid row) to open its Dossier panel: Identification & codes, Vessel draft & hydrography, Container terminal & cargo facilities, Maritime services, and Entrance restrictions.
From a Dossier, click "Add to compare" (up to 4 ports) to line ports up side by side in the Compare view, or "View on map" to locate it geographically.
Check the "Data notes" button for the dataset's sourcing and limitations before relying on any depth or service figure operationally.
Practical Techniques:
Always use the exact UN/LOCODE shown in a port's Dossier on bills of lading, booking confirmations, and customs filings (AMS/ISF, ENS) rather than retyping a port name — carriers and customs systems match on the code, not free text.
Before nominating a port for a large or deep-draft vessel, compare the vessel's laden draft against the recorded Channel and Cargo pier depths in the Dossier — but treat these as a first screen only, since the data notes flag them as single historical soundings, not current charts; always confirm with the port authority or a local agent before finalizing.
Check the Entrance restrictions section (tide-affected, swell exposure, ice-affected) when planning ETAs or laycan windows — a tide-affected entrance may mean the vessel can only cross the bar or enter berth during specific tidal windows.
Use Compare (up to 4 ports) to shortlist alternate discharge or transshipment ports on a route by depth, harbor size, and coordinates side by side, rather than opening each Dossier separately.
Filter to "Major ports only" plus a specific country or continent to quickly build a shortlist of realistic mainline call options on a trade lane, then switch to Grid view and export the filtered set to CSV for a routing spreadsheet.
