Which maps can I get a digital download for?

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

How do I claim my download?
  1. Enter your unique code from inside the cover of the paper map at
  2. You will need to create an account with OS Maps or log-in if you already have an account. By signing in, your maps are saved to your account for use on multiple devices
  3. Enter the 12-character code in the scratch-box on the redeem page. There are no numbers, just letters, so be careful with 'I' and 'O'!
  4. Download the OS Maps app from either Apple App store or Google Play to your device
  5. In the OS Maps app, sign in with the same username and password
  6. You will find the map listed under Menu - Offline Maps - Paper maps
  7. Select the map sheet to download and click the 'download' button
  8. Click on an existing map sheet to jump to it. You may need to zoom in for it to show up. Unlike Premium users, you cannot find them just by changing layer.
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.

Why is the paper map redemption code stating it has already been redeemed?

If you have receive an error message stating your code has been redeemed, please double check the code you are entering. If this is correct then please log into OS Maps app, tap ‘Menu’ in the top left then tap ‘Offline Maps' and then 'Paper Maps'. Your new map should be there ready for you to download. If your map has not been added to your account please contact our customer service team.

Can I use my map on more than one device?

Yes, you can. Download the app and ensure you log in with the same username and password, and all your previously redeemed maps will be available to download on that device. There's no need to enter the code again.

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?

You can download maps for anywhere in Britain by upgrading to a Premium subscription in OS Maps.

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