Codes to download digital copies of maps (found inside the paper Explorer and OL paper map ranges) are not used on OS Maps browser/online; they can only be redeemed and used in the app.

The browser version is ideal for planning routes, for printing paper maps and for importing routes recorded on GPS for analysis. The app version is great for following pre-planned routes, checking your position and local area and recording your trips.
