Location Codes for Freight and Trucking

A truck driver needs something a parcel rider does not: the right entrance. A warehouse can have a street address on one road while its truck gate sits on another, perhaps a kilometre away. A trailer sent to the front door of an industrial estate may have no way to turn around. For freight, the question is rarely "what is the address" but "where exactly do I enter".

The gate versus the address

Industrial addresses often refer to the whole plot. Within that plot there may be a visitor entrance, a staff car park and a goods-in gate. Placing a pin on the goods-in gate and generating a code gives dispatchers, drivers and the consignee one shared reference to the entrance that matters.

Where it fits in the process

• Booking. The consignee drops the pin at the unloading dock when confirming the shipment.
• Dispatch. The code is written on the transport document or the job message next to the written address.
• Driver. The driver opens the code on a phone, sees the coordinates and uses their usual truck navigation to reach it.
• Return loads. The collection point at the next stop gets its own code, so the sequence of stops is explicit.

Planning notes

Because each code marks a 3 m by 3 m cell, a large yard can have several codes: one for the weighbridge, one for the dock, one for the empty-container drop. Label them clearly in your system so that drivers do not confuse them.

Where it falls short

Code lookup is not a truck-routing engine. It will not warn about low bridges, restricted hours or weight limits, and it does not replace consignee instructions such as gate passes or safety induction. It also should not be taken to prove permission to enter a site. Treat it as the answer to "where is the point" only.

For companies with many shipments, the API can resolve codes on the server and attach coordinates to a job automatically; see the documentation for the lookup and generate endpoints. If you also operate smaller vehicles, the page on courier and parcel companies covers last-mile parcels, and construction sites shows a similar gate problem on building projects.
