What Is UPCS and Who Is It For?

UPCS, the Universal Post Code System at upcs.io, gives an exact location a short code. You choose a spot on a map, and UPCS generates a code for it that anyone can look up later to see the same place.

A normal address describes a building or street. A UPCS code points to a precise place, so it is useful when an address is vague, missing a house number, or covers a large site with several entrances.

What a code looks like

Each code follows the pattern CC-XXXX-XXXX: a two-letter country prefix followed by two blocks of letters and digits, for example PK-1A2B-3C4D. Every code corresponds to a 3 m by 3 m grid cell, and the same coordinates always produce the same code. See understanding the code format for more detail.

Who it is for

• Anyone receiving visitors or deliveries. Give friends, drivers or couriers a precise meeting point instead of a long set of directions.
• Shoppers and senders. Add the code to an order or address note so the delivery location is clear.
• Businesses. Partners can use UPCS in their stores through plugins or the API, which is covered separately in the business help section.

What it is not

UPCS complements normal addresses; it does not replace them or the official postal system. Read what a code cannot do before relying on it for anything formal.

How to begin

The fastest route is the quick start: open the map, choose a location, and copy the code that appears. From there you can share it or look up codes other people send you.
