Why standard Live GPS fails: Most leaflet distribution companies use basic 5-second GPS updates. In dense London streets, 5-second tracking drifts 10–15 feet off course—frequently placing deliveries on rooftops, middle-of-the-road traffic, or the wrong houses entirely. A static spreadsheet with 5-second interval data only proves your team walked down a road, not that your leaflet went through a letterbox.
The Private Postman Difference: 1-Second Precision
We built CORE One Step®—the industry’s only 100% transparent tracking system operating at 1-second logging intervals. By tracking postmen second-by-second, we eliminate GPS drift, capture exact doorstep-to-doorstep paths, and stream live, unannounced audit data directly to your client portal.
Live GPS tracking updates only every
5 seconds and can drift 10–15 feet in London, often placing deliveries on rooftops or roads.
This is no proof of delivery.
5-second Excel data can also be inaccurate
because it only gives the whole road’s address.

The average distance from a London path to the letterbox is approximately 10 ft
How does live GPS tracking compare to The Private Postman system?
One of the fundamental issues with live GPS tracking for leaflet distribution is its lack of accuracy.
Most commercial live GPS systems that are being used for delivery tracking tend to operate with a refresh rate interval of about 5 seconds.
This means the distributor’s location is logged and updated every five seconds. Any movement that happens between two update points is not logged or visible. In a densely populated city like London, this becomes a problem.
As we mentioned earlier, the average distance from a footpath to the letterbox in London is approximately 10 feet. It takes less than 5 seconds to walk 10 feet.
As such we believe that live GPS systems are not suitable for tracking leaflet distribution in London.
They simply do not operate at a resolution good enough to provide meaningful information about the quality of deliveries.
At The Private Postman, we aim to maximise the accuracy of our tracking systems, which is why we do not offer live GPS tracking. Instead, we run our own system that tracks to One Human Step. Due to this level of accuracy, while combined with other elements of our service, it can act as a proof of delivery.
In our view, live GPS systems might be suitable for tracking long distance deliveries, like parcels. Not leaflet distribution.
The Private Postman has not only set out to build the best system in London or the UK, but globally.
That is the level of commitment we have.

Disclaimer: We are human. CORE GPS tracks can still show odd flat lines where houses are one step from kerb, like parts of N1/W1, or where parts of streets are walked past to avoid council blocks or where houses have letter boxes on outside of gates, or where rubbish bins have blocked delivery to the occasional house.
