If the mobile number linked to the UPI account is reassigned to a new user, can the new user access the previous owner’s bank account funds?
I’d appreciate any insights or additional information on this.
Thank you!
Yes, and that is the method used by the scammers which is called swim swapping.
But it's highly unlikely to get access of someone's number because every number is linked with unique Aadhar number so one who wants to buy the number has to provide the KYC documents with liveness test but this can be passed easily if you have someone inside the service provider.
