Location QR code generator
A location QR code holds a latitude and a longitude, and scanning it offers to open that spot in a maps app. Opo Codes makes it for free in your browser, with no account, and checks that the code reads back before you print.

How to do it
- Open the generator with Location already selected.
- Type the latitude, then the longitude, in decimal degrees such as 22.3569 and 91.7832.
- Tick the maps link option only if you want a web link instead of a plain location.
- Wait for the VERIFIED stamp, then download the code.
What is inside the code
By default the code holds a geo: link with the two numbers, which phone maps apps understand. If you tick the maps link option it holds a web address with the same position instead, which also opens on a computer.
Worked example: latitude 22.3569123456 and longitude 91.7831987654. Numbers are rounded to 6 decimal places, about 11 centimetres, so the code holds geo:22.356912,91.783199. More decimals would only make the code denser without placing the pin more exactly.
Latitude first, longitude second
Latitude runs from -90 to 90 and longitude from -180 to 180. People often swap them. In Dhaka the latitude is 23.8103 and the longitude 90.4125. Type them the wrong way round and the latitude would be 90.4125, which is out of range, so the generator refuses the code and says so.
The check only catches a swap when one number is outside its range. For a place where both values fit both ranges, look at the pin on the map after you scan.
Finding the numbers
Most maps apps show a spot's coordinates when you press and hold it, and you can copy them. Use the entrance, not the middle of the building, if people will be walking or driving to it. Scan the printed code once on site to confirm that the pin lands where you meant.
Questions
geo: link or maps link, which should I pick?
The default geo: link is meant for the phone's own maps app. The maps link is a web address, so it also works on a computer and in apps that do not read geo: links.
Does the code show my address as words?
No. It holds only the two numbers. Add the street name next to the printed code for people.
Can I add a place name?
The form takes only the two numbers. Print the name beside the code.
Can I change the spot later?
No. Static codes cannot be edited, so print a new code if you move.
