    You can use UPCS from the browser on a phone or tablet. Open upcs.io, and the same features are available as on a computer: creating a code, looking one up and sharing it.

    Create a code on your phone

    1. Open upcs.io in your mobile browser.
    2. Open the map and move it with your finger.
    3. Pinch to zoom in until you can see the exact spot.
    4. Choose the location. The code is shown.

    Zooming in matters even more on a small screen, because a fingertip covers a wide area. Take a moment to confirm the position. See zooming in to the entrance.

    Look up a code on your phone

    Paste the code into the search box at the top of the site, or open a link someone sent you, such as upcs.io/PK-1A2B-3C4D. The lookup page then offers Open in Map, Get Directions, Share / Copy link and Copy coordinates. Read get directions from a code to see how to start a route.

    Sharing from your phone

    Copy the link or the code and paste it into your messaging app. Sharing a code by message covers what to include.

    Tips

    • Use a recent version of your browser for the best map experience.
    • Keep an eye on your connection; the map needs to load to display the location.
    • If the page does not behave as expected, reload it and try again.

    UPCS is not available offline, so a connection is needed to create or look up codes.
