UN/LOCODE codes are an international standard for encoding ports, terminals, and other cargo handling locations. They are used to streamline logistical and trade operations worldwide.

‍

Applications of UN/LOCODE:

• Logistics and Transportation: UN/LOCODE aids in precise identification of loading and unloading points for cargo. This simplifies route planning, carrier selection, and delivery monitoring.
• Customs and Clearance: UN/LOCODEs help customs authorities accurately determine the destination and source of goods for customs clearance.
• Trade and Commerce: Manufacturers, suppliers, and trading companies use UN/LOCODE to identify ports when planning deliveries and organizing transportation.
• Monitoring and Analysis: Data on the movement of goods through specific ports, collected using UN/LOCODE, facilitates analysis and the determination of logistical chain efficiency.

Advantages of UN/LOCODE:

• Standardization: UN/LOCODE establishes a consistent identification format for all locations worldwide, promoting uniformity and mutual understanding.
• Convenience: These codes are easy to use and distribute in international documents and software systems.
• International Support: UN/LOCODE is supported by the International Telecommunication Union (ITU), ensuring its dissemination and updates.

UN/LOCODE codes are also used in systems such as:

• Global Shipment Tracking System (GSP)
• Electronic Data Interchange (EDI)
• Other logistics systems

International Port Codes

International port codes are unique identifiers assigned to ports worldwide. They are used to label ports in logistical documents like bills of lading, waybills, and invoices.

International port codes consist of five characters divided into two groups:

• The first two characters represent the country code according to ISO 3166-1 alpha-2.
• The following three characters are a unique code for a specific port or terminal.

International port codes are maintained and administered by the United Nations. They are part of the international UN/LOCODE standard, which also includes codes for other cargo handling locations like terminals, warehouses, and customs points.

How to Find Ports Worldwide?

• Official Websites of Sea ports and Terminals: Most seaports have official websites where you can find detailed information about their services, infrastructure, and contact information. Simply enter the name of a specific port into a search engine to find its website.
• International Organizations and Agencies: Organizations such as the International Maritime Organization (IMO) and the International Union of Railways (UIC) provide information about seaports, including their identification, coordinates, and handling capacities.
• Specialized Online Resources: There are websites and databases specializing in providing information about seaports worldwide. One such resource is "World Port Source" (www.worldportsource.com), where you can find a wealth of information about ports and their functions.
• Maps and Geographic Services: Using mapping services like Google Maps or OpenStreetMap allows you to locate seaports and determine their coordinates.
• International Port Codes: You can use International Port Codes, such as UN/LOCODE (which I mentioned in previous responses), to identify specific seaports. These codes can be found in official sources, such as the website of the International Maritime Organization (IMO).
• Maritime Portals and Directories: There are online portals and directories that store information about seaports and provide access to detailed data about them.
