Once you have accepted the terms and conditions, you will be asked for your client number.
Your unique client number is a simple way of identifying yourself with ING.
You can easily find your client number from the following:
Your Access Code is the 4-digit code that you use to log in to ING and is a security measure to verify your identity and access your account. Don’t remember it anymore? No worries, reset it on the Legacy ING App or through Online Banking.


How you reset your access code using online banking depends on if you’ve registered to receive SMS security codes.

If you’ve tried 3 times and been locked out, call us on 133 464 so we can reset it for you.
You can reset your access code using the ING App or Online Banking.
Your current 4 digit Access Code will remain essential to access online banking, customer service and to reset the app if you forget the Mobile Pin (see step 3).
The new Mobile Pin is attached to the device you are choosing it on. Once set up, you will always need this Mobile Pin to access the app. Alternatively, if you activate biometric recognition, you will no longer have to enter it and you will be able to access with a glance or a finger.
For security reasons, we’ll send you an SMS security code to your registered mobile number so that you can finalise your set up. You can check that your mobile number is up-to-date and valid in My profile on the legacy ING App or in online banking. If you need to update your mobile number call us on 133 464. Alternatively, visit our Contact Us page to view our free call numbers available from selected countries. You may not be able to receive SMS security codes if travelling internationally and using a travel SIM where the phone number is different.
Check that you are registered for SMS security codes by visiting the My profile tab on online banking.
You are ready to start using the new ING app. Stay tuned and be the first to use new features the moment they are released!
In the meantime, you can still use the legacy ING app or online banking to get it done. We’re working hard to bring everything together in one place soon!
