How the address is found
Your browser first provides coordinates after you allow location access. Those coordinates are then matched against map address data. Depending on local coverage, the result can include a house number, road, neighborhood, city, region and postal code.
If the street address looks wrong
Compare the pin with the map before copying the address. Dense buildings, indoor positioning and incomplete address databases can place the point on a nearby road or parcel. Running the check again outdoors can improve the device reading.
