Cold Chain and Temperature-Controlled Delivery

Cold-chain goods are on a clock. Vaccines, fresh food, lab samples, flowers and frozen products all have a window during which they must be handed over. Most of that window is spent in controlled storage and well-planned linehaul. The risk concentrates in the last kilometre, where a driver is hunting for the right entrance with the refrigeration unit working harder every time the door opens.

The location problem

Receiving points are often not the street address. A clinic has a staff entrance, a goods bay and a front desk; a food plant has a gate for each department; a market stall has a corner behind a delivery lane. A driver sent to the main gate wastes cold time driving around the perimeter, and a receiver who has to walk out and wave is not at their cold store.

Why a code helps

The code is the exact location of the receiving point. When the receiver picks the loading door on the map, the 3 m x 3 m square it produces is the spot your driver arrives at, every time. There is no ambiguity between the front of a building and its goods entrance.

How to use it

1. Set up receiving points. Have each recipient choose their goods entrance on the map. Save the code against the customer in your system.
2. Put it on the manifest. Print the code and link beside the stop. One tap opens the spot with Get Directions.
3. Integrate where needed. Developers can fetch the location of a code through the REST API using a partner key, or create codes for known sites. See the documentation.
4. Add a note. Keep opening hours or the bay number next to the code as a helpful extra.

Why minutes matter at the door

Chilled and frozen loads travel in refrigerated vans or insulated boxes with a limited holding time outside temperature. Every stop adds door-open time, and every minute spent finding the entrance is a minute the cargo is not at its destination. Receivers also plan around the delivery, for example by keeping a staff member free at the bay. When the recipient has picked the receiving door once, the driver heads straight there, and the handover happens inside the window both sides planned for. UPCS does not monitor temperature or track vehicles; it simply settles where the vehicle should stop.

Tips

• Pick the door, not the building centre, whenever the map is zoomed in far enough to see the grid.
• Share the same code with relief drivers so a replacement does not depend on local knowledge.
• Your own planning tools can take the coordinates from a lookup; UPCS itself does not plan routes.
