How to create it
Find the coordinates. In Google Maps, press and hold the spot (or right-click on a computer) and copy the two numbers shown. In OpenStreetMap, right-click and choose “Show address”.
Enter latitude and longitude in decimal degrees. Latitude is the first number and ranges from -90 to 90; longitude ranges from -180 to 180.
Choose the format. A map link to OpenStreetMap or Google Maps opens on every phone; the geo: format hands the coordinates to the default map app.
Scan the preview on an iPhone and an Android phone and check that the pin sits on the right entrance.
Printing and placement
- On an invitation or a delivery note, a 3 cm code is fine. On a sign at a car park entrance, use the one-tenth rule for the distance from the driver's seat.
- Print the street address next to the code as well, for people who prefer to enter it into their own navigation app.
- If the code is for a hidden entrance or a meeting point, say so in a short line, for example “Entrance for deliveries”.
Common mistakes
Latitude and longitude swapped
Swapping the two numbers puts the pin in a completely different part of the world. Latitude comes first; for Europe it is the larger of the two numbers.
Too few decimal places
Two decimal places locate a point only to around a kilometre. Use five or six decimal places for a precise entrance.
Relying on geo: alone
Not every camera app opens geo: links. If you are unsure which phones your visitors use, choose one of the map link formats.
Which format to choose
The geo: URI is defined in RFC 5870 and contains only the coordinates, for example geo:53.5511,9.9937. Android passes it to the default map app. Support on iPhones is less consistent, which is why the generator also offers map links.
A link to OpenStreetMap or Google Maps is an ordinary web address. It opens in the browser on any phone, and if the Google Maps app is installed, the Google link usually opens there.
Questions
This is a static QR code: the content sits in the code itself and works without our server.
Static and dynamic QR codes explainedCan I enter an address instead of coordinates?
The generator works with coordinates, because they point to the exact spot. You can look them up in any map service as described in the first step.
Does the code need an internet connection?
The coordinates are stored in the code. A geo: link can open in an offline map app; map links to websites need a connection to load the map.
Which decimal separator should I use?
Use a point, as in 53.5511. A comma is also accepted and converted automatically.
Can I share a whole route?
No, the code holds a single point. The phone's map app calculates the route from the user's position.
