The verdict in three sentences
In a city where under 30 % of addresses are formal, free-text addresses are the number-one cause of last-mile failure. Requiring a GPS pin or WhatsApp location share at checkout cuts failures by 25 to 40 % and saves 8 to 15 minutes of searching per parcel. The 2026 decision: make the GPS pin mandatory at payment, with a landmark as backup.
Why free-text addresses fail
In Kampala, an order described as "near the market, house with a blue gate" sends the rider on a treasure hunt. Here is the quantified impact of location methods in 2026.
| Location method | Failure reduction | Search time saved |
|---|---|---|
| Free-text address | baseline (0) | 0 |
| Landmark + phone | -10 to -18 % | 3 - 6 min |
| WhatsApp location share | -20 to -32 % | 6 - 12 min |
| GPS pin at checkout | -25 to -40 % | 8 - 15 min |
| what3words / address code | -22 to -35 % | 7 - 13 min |
The GPS pin is the most effective, but plan a backup: landmark and verified phone number for low-signal areas.
The cost of a mislocated parcel
A rerouted or unfindable parcel is expensive in time and trips. Here are the 2026 orders of magnitude in Kampala.
| Item | 2026 estimate |
|---|---|
| Cost of a rerouted parcel (FCFA eq.) | 800 - 2,000 |
| Urban GPS accuracy | 5 - 20 m |
| Formal addresses in the city | < 30 % |
| Location-share adoption | 60 - 75 % of customers |
| Average search time avoided | 8 - 15 min/parcel |
On 100 mislocated parcels avoided per month thanks to the GPS pin, the saving runs into tens of thousands of FCFA of rerouted trips plus hours of rider time.
Mini case study
Okello delivers electronics in Kampala: 60 parcels/day, 30 % address-related failures (18 parcels), reroute cost 1,500 FCFA, or 27,000 FCFA/day of losses plus 18 x 12 min = 3.6 hours of wasted time.
He makes the GPS pin mandatory at checkout. Address failures drop to 12 % (7 parcels), or 10,500 FCFA/day: a saving of 16,500 FCFA/day and over 2 hours of rider time, on a one-off configuration investment.

FAQ
Is the GPS pin reliable in dense Kampala?
Urban accuracy is 5 to 20 m in 2026, enough with a landmark backup. In low-signal areas, WhatsApp location sharing takes over.
Will customers agree to share their location?
Adoption reaches 60 to 75 % when the share is asked simply at checkout or via WhatsApp. A clear message about faster delivery raises acceptance.
Should I drop the text address?
No, keep it alongside the pin, not instead of it. Text serves as a backup when GPS drops, but the pin should remain the main field.
Is what3words worth it over a classic GPS pin?
Both cut failures by 22 to 40 %. what3words is easier to dictate by phone, the GPS pin is more direct from a smartphone: offer both.
How much does adding a GPS pin to my store cost?
It is a checkout configuration, paid back from the first better-located parcels as in Okello's case. The main gain is rider time and avoided rerouted trips.
