For a list of Ordnance Survey One-Inch, 1:50,000 and six-inch County series map sheets on which a particular location appears type a British or Irish address, post code or place name in the location box or pan and zoom the key map. Double-click on a location to add a marker at that point. An infobox will display the results, and the marker can be dragged to the desired position.
Results appear in the infobox and below the map, in many cases with a link displaying the sheet itself. The gazetteer is provided by Google Maps and will attempt to resolve partial or ambiguous locations. You may need to add a county name or pan and zoom the key map to show required location.
