Union Bank of India: complaint, nodal officer and fraud contacts
Where to report a fraud and how to take a complaint up the ladder with Union Bank, using only the contacts Union Bank publishes on its own website, in the order to use them. IFSC Bank Guide is independent and not linked to Union Bank.
If money has just left your account
Do these now, in this order:
- Call 1930, the national cyber crime helpline, or report at cybercrime.gov.in.
- Call Union Bank’s fraud line, 1800 2222 43, and ask for your account, cards and UPI to be blocked.
- The same day, complain in writing at the first level of the ladder below, and keep the complaint number you are given.
Speed matters. If the fraud came from a breach elsewhere in the system, not from you sharing a PIN or OTP, reporting it within three working days of the bank’s alert keeps your liability at zero for transactions up to 31 December 2026. For transactions from 1 January 2027, the window is five calendar days from the fraud. What the RBI rules say.
Union Bank’s complaint ladder
Go up a level only if the one before it has not solved the problem, and quote your earlier complaint number each time. These are the contacts Union Bank gives on its own website:
Report fraud now
Call first to block your account and cards. Lines are listed by the bank for unauthorised transactions.
Phone: 1800 2222 43
Level 1 · Customer care
Your first written complaint goes here.
Email: customercare@unionbankofindia.bank.in
Phone: 1800 2333, 1800 208 2244
RBI Ombudsman
If Union Bank does not reply within 30 days, or you are not satisfied with the reply, complain at cms.rbi.org.in or call 14448 for guidance. File within 90 days of the bank’s last reply, or of the 30 days running out. It costs nothing.
The Union Bank pages we checked do not give a separate grievance redressal officer or Principal Nodal Officer. We show only what the bank publishes; if you need one, ask customer care for it in writing.
Our free tools can draft the letter for you:

Union Bank IFSC codes
Every Union Bank branch code has 11 characters: UBIN, then 0, then six characters for the branch, like UBIN0XXXXXX. If a code someone sends you does not start with UBIN, it is not a Union Bank branch.
These banks are now part of Union Bank. Their old codes no longer work, so ask your branch for the current code or look it up above:
- Andhra Bank (ANDB): merged on 1 April 2020; old codes stopped working from 1 April 2021.
- Corporation Bank (CORP): merged on 1 April 2020; old codes stopped working from 1 April 2021.
More in our guide to bank mergers and old IFSC codes.
Is it really Union Bank?
Union Bank’s website is www.unionbankofindia.bank.in. The email addresses on this page end in @unionbankofindia.bank.in.
- No bank asks for your OTP, PIN, CVV or password, by phone, SMS, email or WhatsApp.
- A “Union Bank officer” writing from Gmail or another free email address is not Union Bank.
- Check any number or link you are sent against this page or www.unionbankofindia.bank.in before you call or click.
- Beware the second scam: no bank, police force or “recovery agent” charges a fee to get your money back.
