A code leads to exactly the spot you picked, so choosing it well pays off. A thirty-second check before you share it can save a missed delivery or a wasted trip.
Checklist
- Look up your own code. Paste it into the search box on upcs.io or open
upcs.io/PK-1A2B-3C4Dwith your code. - Check the country. The lookup page shows it. It should match the country you are in.
- Open in Map. Use the Open in Map action and look at the marker. See opening a code in the map.
- Zoom in on the UPCS map. The 3 m by 3 m grid appears from zoom level 18, so you can see which cell you are choosing.
- Compare with the entrance. Is the cell where a visitor should arrive, or in the middle of the property, or on the wrong side?
- Choose again if needed. If it is off, go back to the map and select a better point. Zoom in to the entrance has guidance.
Common slips
- Choosing the building centre instead of the door.
- Choosing a point while zoomed far out, so the marker covers a wide area.
- Picking the wrong side of a street or a neighbouring plot.
After the check
When you are happy, copy the share link or give the code to a courier.
If you received the code
The same steps apply, and verifying a code someone sent you covers what to do if it does not match what you were told.
Frequently asked questions
How precise is a UPCS code?
A code corresponds to a 3 m by 3 m grid cell, so a small shift in where you choose can lead to a different code.
