Our friend wants to know about changing the account number linked to their City Union Bank VPA (Virtual Payment Address). They want to deregister an existing account number and link a different account number instead. Thank you very much. Regarding the account number, we should mention that the new number should also be registered with your bank account—the same way the previous account was. That is, the new account must be linked to your mobile number and Aadhaar as well. So, when you call City Union Bank’s customer service at 1800-425-1657, you need to press the hash (#) key, which is located just below the number 9 key, to access the full menu. Once you do that, a full menu will appear on the call, giving you various options. From there, you can choose to: Deregister your old VPA using UPI Change your UPI PIN Change or link a different account number Follow the instructions provided in the menu to complete the service. We hope this explanation is clear and understandable, so you won’t need to ask any further questions.
