Mobile download FAQ


OS Maps on iPhone Example Explorer Map

With selected OS maps you can now download a copy for use on your Android or iOS smartphone or tablet. Each paper map has a unique code that will give you access to the same mapping using our new app, OS Maps.

Just scratch off the silver panel on the inside cover, enter the code and then download your map inside the app.




Which maps can I get a digital download for?

All current edition OS Explorer maps in 1:25 000 scale and OS Landranger maps in 1:50,000 scale have the mobile download available. Look for 'Includes mobile download' on the cover. Tour maps will not have mobile downloads, but the OS Maps app has a simple map available for free.


How do I claim my download?

Go to and follow the instructions. You will need to have a unique code from a paper map. It is printed on the inside cover underneath a scratch-off panel.

  1. You will need to sign in using an existing OS Shop / OS Maps username and password, or create a new one. We need you to sign in so your maps can be saved to your account for use on multiple devices.
  2. Scratch off the silver panel from inside the front cover of the map. Enter the 12-character code in the box on the redeem page. There's no numbers, just letters, so be careful with 'I' and 'O'!
  3. Once redeemed, that map is available in the OS Maps app. Follow the links to download the app, then sign in with the same username and password. You will find the map listed under Menu - Offline Maps - Paper maps
  4. Select the map sheet to download and click the 'download' button
  5. Click on an existing map sheet to jump to it. You may need to zoom in for it to show up.


Why is my code not working?

The most likely cause of this is the entry of the code, please note that:

  • The codes are all 12 letters, with no numbers - avoid using zero and one
  • All the letters are printed in upper case, so be aware of I (i) and L (l)
  • You do not need to type the dashes between the letters

You only need to redeem the code once, no matter how many devices you have the OS Maps app on. If your code fails to redeem with 'code burnt' or similar, check your maps list in the app to see if you already have that map available. This can occasionally happen even on the first attempt if you have an intermittent internet connection.

If your code is still not working please contact us for help.


I've borrowed a map - can I get a digital copy?

Each code can only be used once, so if someone else has already used it, you will not be able to.


Can I buy just the digital map?

Not at the moment. However, you can upgrade to a Premium subscription in OS Maps to download maps anywhere in the country on your mobile device, and see them on any desktop devices.


I've just bought a map and the scratch-off panel has already been scratched off

Please contact the retailer to replace the map to get a new code.

Where can I find out more about using the app?

The app is designed to be intuitive to use, but we have created an FAQ to answer some of the most common questions: OS Maps app FAQ.


What happens if I delete a map or change my phone?

Maps you have purchased and redeemed the code for are stored against your account in the OS Shop. If you delete the map, change your phone or even switch between an Android device and an iOS one, you will still have access to your maps. In the OS Maps app please ensure you log in with the same username and account as you use on this site and the list of available maps will be shown under 'My Maps'

This means that you may want to add a map just for a trip or holiday and then delete it afterwards to save space, with the knowledge that you can download it again at any time.


I don't have an Android or iOS device - how can I use the mobile download?

At the moment we only have apps available on Android and iOS devices, so you will not be able to use the mobile download.


Can I use the mobile download on a Garmin, SatMap or other GPS device?

No. GPS devices use different file formats which are controlled by the device manufacturer. Contact your GPS manufacturer for updated maps. We carry some maps for the most popular brands in our Shop > GPS Accessories.


Can I use the mobile download with any other desktop software or app?

No. Every maker of mapping software uses different formats for their map downloads to work with that specific software. You will not be able to use your download on other desktop software or apps, Please contact the manufacturer or supplier of your software or app to obtain updated or additional maps.


Can I use the download on OS MapFinder?

OS MapFinder was released before mobile downloads were available and we have decided to use the newer OS Maps app for the mobile downloads as this supports newer devices and integrates better with the desktop browser version.

OS MapFinder is no longer being updated, but is still available for existing users. The OS Maps app supports the downloads included with paper maps and offers all of Great Britain for an monthly or annual subscription. You can continue to use both apps if you already have tile purchases, or contact Customer Services to get your old MapFinder tiles converted to the equivalent on OS Maps..
