Accuracy and Privacy FAQ: UPCS Location Codes
Answers about the 3 m x 3 m UPCS cell, location accuracy, whether a code is official, and how to share a precise location safely.
Updated 14 October 2026 · 4 min read
A UPCS code points to a small 3 m by 3 m cell, which makes it precise, but precision also deserves some care. These answers explain what the cell means, what accuracy to expect and how to share a location safely. For the full legal details, see the privacy policy.
Frequently asked questions
What does the 3 m x 3 m cell mean?
UPCS divides the map into square cells that measure 3 metres by 3 metres. Every point inside one cell shares the same code.
How accurate is a UPCS code?
A code identifies a 3 m by 3 m square, so it leads to the exact spot you picked on the map. For the best result, zoom in and pick the gate, door or entrance you want people to reach.
Is a UPCS code more accurate than my phone's GPS?
A UPCS code leads exactly to the point you choose on the map. Phone GPS readings can drift a few metres indoors or between tall buildings, so for the best result zoom in and tap the spot you mean rather than relying on a detected position.
Why does my location look slightly off on the map?
A detected position can drift because of buildings, weather and the device itself. Zoom in on the map and tap the exact spot you mean, and the code will lead to that spot.
Can the cell be on the wrong side of a wall or fence?
The cell is the 3 m square you picked, so choose the point at your entrance or gate and the code leads people right there. Zooming in to the grid makes it easy to place the point exactly.
Is a UPCS code an official postal code?
No. A UPCS code is not issued by any government or postal operator and does not replace national postal systems. It complements a normal address with an exact location.
Can I use a UPCS code as my legal address?
No. Legal and postal use requires your official address and, where applicable, your official postcode. A UPCS code is an extra aid for finding the location.
Does UPCS work with postal services or governments?
UPCS is not integrated with any postal operator or government. It is an independent system that can sit alongside official addresses.
Is my UPCS code private?
A code points to a place, so anyone you give it to can look up that location. Share it only with people you want to know where it is.
Can someone track me live if I share a code?
A code stands for a fixed cell, not for you as a person or your live movement. Sharing it shows a place, not where you are at a given moment.
What personal information does UPCS use to sign me in?
Sign-in uses your WhatsApp number and a one-time code. For how personal data is handled, read the privacy policy on the UPCS website.
Should I share the code for my home publicly?
Be careful. A precise code makes it easy for anyone who sees it to locate your door, so avoid posting it on public pages and share it only with people you trust.
Is it safe to give my code to a delivery driver?
It is common to share a location with a delivery driver for a specific order. Use the order channel provided by the shop or courier and avoid posting the code publicly.
Should I use my home code when meeting someone I do not know?
It is safer to pick a public meeting place and share that code instead of your home. Keep your own address private until you trust the other person.
Can I use a code for a place that is not mine?
You can generate a code for a location in a supported country, but be respectful of other people's privacy. Do not share the code for someone else's home without their permission.
Will a driver find me with a UPCS code?
A UPCS code leads whoever opens it to the exact location you picked, which is the surest way to point a driver to your door. Arrival timing is up to the driver or courier, so a landmark or floor number is a helpful extra.
Where can I read about how my data is handled?
The privacy policy on the UPCS website explains how personal data is handled. This FAQ does not describe data storage or processing.
Does a UPCS code ever move or drift?
No. A code is tied to its 3 m by 3 m cell on the map, so it always leads to the same square.
How do I get the best result when picking a spot?
Zoom in until the grid appears and pick the exact point you want people to reach, such as the gate, door or car park entrance. The code then leads straight to that spot.
Can I trust a UPCS code for a hard-to-find place?
Yes. A code leads to the exact square you picked, which makes it a strong choice for places that are hard to describe, such as a farm entrance, a site gate or a spot in a large estate.
