About UCO Bank
Net banking, the mobile app, UPI, cards and general account queries are covered by the 24x7 toll-free line that UCO Bank runs itself. Those official details are listed here so customers reach UCO Bank directly.
For a lost or stolen card, call and ask for an immediate block, keeping your account or customer ID ready. UCO Bank does not ask for your OTP, PIN or password over phone, so any such call is a scam.
