Wrong address for the business: 1637 South Old Hwy 141, Fenton, MO 63026. New address: Grateful Motors is at 4046 Jeffco Blvd, Arnold, MO 6301.0. How do I get some help here at OpenStreetMap to make the change? I’ve flagged it 10 or more times and emailed the company, but they’ve provided no help.
On a PC, browse to the area that you are interested in. Click the “edit” button at the top of the screen. You’ll be taken through a “how to map” introduction, and after that you can click on “Point”, click on the map where you want to add it, and then search for “car dealership” (or whatever). Then fill in the details based on your local knowledge and “save”.
