UCO Bank offers multiple ways to generate or reset your 4‑digit ATM PIN (called Green PIN), all requiring your registered mobile number to receive an OTP. You can activate even an inactive card this way.
1. Via UCO Mobile Banking App (UCO M‑Banking Plus)
- Log in and select Manage Cards → Green PIN Generation.
- Choose your account and card; validate by entering the full 16-digit card number and expiry date.
- Enter a new 4-digit PIN, confirm it, then verify with the OTP and your TPIN.
- PIN will be set instantly and SMS confirmation sent. If the card was inactive, it becomes active automatically.
2. At UCO Bank ATM
- Insert your debit card and choose the Green PIN option from the language screen.
- First select Generate OTP, enter your account number to receive the OTP on your phone.
- Reinsert your card, choose Validate OTP, input OTP, and set your desired PIN (re-enter to confirm).
- PIN setup completes immediately.
3. Via UCO Bank Website
- Visit the official UCO Bank site and go to the Generate Green PIN page.
- Complete required inputs: account details, OTP, and new PIN.
- This process allows only one debit card or ATM transaction up to ₹10,000 or POS usage until midnight the following day; e-commerce payments are blocked until then.
4. IVR (Phone Banking)
- Call the toll‑free number 1800‑8910 from your registered mobile.
- Follow step-by-step IVR prompts to generate the OTP.
- Complete the PIN setup at a UCO ATM using that OTP.
- Same ₹10,000-limit restriction applies until the next day midnight.
