KYC is required for you to get a virtual topup account on NOSH, which is the only service it is required for.
The virtual bank account operates like a normal bank account, which, according to CBN policy, must be registered under your BVN. Not to worry, your BVN information is safe with NOSH.
Note that you can carry out other activities and withdrawals without completing this process. But, if you need a virtual bank account to deposit to your NOSH WALLET, KYC is required.
