Updating the mobile number linked to your Luno account is easy to do by following a few simple steps.

Here’s how

Change your number

  1. Sign in to your Luno account with your email address and password, as well as your two-factor authentication (2FA) code if you have 2FA enabled 

  2. Select Profile from the menu, and then Settings

  3. Select Mobile number from the options

  4. If you have a trusted device, you’ll automatically proceed to step 6

  5. If you don’t have a trusted device, a pop-up will display asking if you still have access to your old mobile number

    • If you do, select YES, and you’ll proceed to step 6

    • If you don’t, select NO, and you’ll proceed to account recovery - see below

  6. Type in your new mobile number, and then select NEXT

  7. You’ll then need to enter a confirmation OTP, which will be sent to your new mobile number


If you’re updating your mobile number on the web, select the three small dots  on the right-hand side of your verified mobile number, and then Change.

Authorise the change

Once you’ve entered the OTP, you’ll need to authorise this change, so that we can verify that you did, in fact, initiate the change. You’ll receive an authorisation link via either:

  • Push notification - if you have a trusted device

  • Or SMS - to the existing mobile number on your account

Clicking on the link will open an authorisation screen, where you can choose to approve or deny the change.

Mission success! You’ve successfully updated your mobile number.

Account recovery

If you don’t have a trusted device and no longer have access to your old mobile number, you can use account recovery to change your mobile number.

  1. When selecting Mobile number from your Settings as outlined in step 3 above, a pop-up will display asking if you still have access to your old mobile number

  2. Select No

  3. You’ll be taken to Account recovery so that you can update your mobile number


You’ll need access to your primary email and you’ll be required to confirm details associated with your account. It takes 48 hours for the mobile number change through account recovery to take effect. This is an additional security measure to ensure that it's actually you requesting the update. If you receive an email notification, and you haven't requested the mobile number change, please report it to us immediately.
