Definition
UPI Bank Mapping is the process that connects your UPI ID or mobile number to a specific bank account in NPCI’s centralized database. This mapping allows the UPI system to identify which bank account to debit or credit when a transaction is initiated.
Purpose
This is especially useful when you have multiple bank accounts or use different UPI apps. It ensures that the correct account is selected as default and that your transactions are routed correctly. Without accurate mapping, UPI transfers may fail or be misdirected.
