About City Union Bank
1800 120 5000 is the line City Union Bank prints as its 24x7 customer care for all states, covering net banking, the CUB All in One app, UPI, cards and account queries. Written queries and complaints go to [email protected]. From outside India the bank gives a Chennai number, and that same number is its WhatsApp banking line.
Some things do not need a call. A missed call returns the balance, an SMS blocks the net banking login, and a complaint raised on the bank's own portal comes back with a service request number you can quote later.
Keep the account or customer ID ready before you dial. No CUB officer will ask you for an OTP, a PIN or a password, and the bank's own advice is that its genuine SMS arrives under the CUBANK and CUBLTD sender headers.
