When to call Union Bank of India
- An unauthorised transaction or a lost card — call immediately, before anything else, and ask for the card and account to be blocked.
- A debited amount that has not arrived or reversed after the bank's stated window.
- Login locked after repeated attempts, or a suspected fraud call or message claiming to be the bank.
- Cheque, loan or account-opening questions that the app and net banking do not answer.
Support e-mail
E-mail is slower than the phone but creates a written record — useful for refunds, disputes and anything where you may need to escalate later.
Beware of fake customer care numbers
- Genuine support staff never ask for your PIN, password, OTP or full card number — on any call, ever.
- Never install a screen-sharing or remote-access app because a "support agent" asked you to.
- A refund never requires you to pay first or scan a QR code. Scanning and entering your PIN always sends money out.
- If a number came from a social-media post, comment or an unknown website, verify it on the official website before calling.

This page lists 5 published numbers in total, each labelled with what it is for — general support, fraud reporting and special desks are often different lines, so pick the one that matches your problem to reach the right team faster.
Is the Union Bank of India helpline toll-free?
Yes. At least one Union Bank of India line listed here — including 18002333 — is toll-free, so calling it costs nothing from any network in India. A few special-purpose lines may be standard-rate numbers; each entry on this page is labelled so you can tell them apart before you dial.
What are the Union Bank of India customer care timings?
At least one Union Bank of India line on this page is marked 24x7, which includes the fraud and emergency desks — those never close, because a stolen card or a suspicious transaction cannot wait for office hours. General enquiry lines may keep day timings, so for non-urgent questions a weekday morning call usually means the shortest queue.
What details should I keep ready before calling Union Bank of India?
Keep your registered mobile number, the account or reference number connected with the problem, and the date, time and amount of any failed transaction, with its transaction ID if you have one. Write down the name of the person you speak to and the complaint or docket number they give you. Never keep — or share — your PIN, password or OTP: genuine staff will never ask for them.
