Sometimes, even one number makes a huge difference. In March 2021, the Wikimedia Foundation received an inquiry from a property owner’s representative, who demanded we correct their client’s address on Wikipedia. They claimed a late British singer’s Wikipedia article and Google Maps erroneously listed the street number for their client’s property as the late singer’s address. This tiny error resulted in delivery drivers, taxis, and others looking for the singer’s estate turning up at another property owner’s home. After careful evaluation of the official copy of the title plan and map reference, our team requested the English Wikipedia volunteer group to remove the address, which they did.
