If I attempt to locate my driveway by address - the "red dot" is alway about 250 feet north of the actual beginning. I don't know what system the Post Office used back in 1982 but it certainly does not match up with todays systems.
That reminded me - some painting contractor's pin and description were at my location. I never heard of the guy. After I sent several notes to Google it disappeared.If your talking about google maps, you as an end user can submit an edit and correction for that.
I did, my house location was at my neighbors milking barn. A quarter of a mile, down the road.
