Union Bank of India Customer Care Numbers: Verified Contacts, Hours, and Practical Guidance

Official 24×7 Customer Care Numbers (India)

Union Bank of India operates unified, round-the-clock helplines for retail, card, digital, and general banking support. The two primary toll-free numbers you can dial from anywhere in India are 1800 22 2244 and 1800 208 2244. These lines route through the IVR to dedicated teams for card blocking, net banking/UPI issues, account inquiries, and dispute logging.

Both numbers are available 24×7, including Sundays and public holidays. Expect shorter wait times in non-peak windows (typically 07:00–10:00 and 21:00–23:00 IST). For urgent security actions—like blocking a lost/stolen debit card—use these lines immediately; the block is applied instantly and you’ll receive a confirmation via SMS.

Missed-call services work only from the mobile number linked to your Union Bank account. Calls disconnect automatically and you receive an SMS with the requested info within about 30–60 seconds. If you don’t receive an SMS, confirm your number is updated in the bank’s records and that you have network coverage.

Always use the bank’s official domains listed above. Union Bank of India’s main site ends with .co.in and their online banking portal ends with .co.in; avoid lookalike domains. For secure login, verify the SSL lock icon and the full URL before entering any credentials.

What You Can Resolve Over the Phone (and Typical Timelines)

Most day-to-day issues can be handled without visiting a branch. Common examples include debit card blocking/unblocking, hot-listing suspect transactions, resetting net banking access (after identity verification), enabling/disabling international usage, updating email IDs, registering mobile numbers for SMS alerts, and raising service requests for chargeback/disputes. Card blocks and channel controls are applied in real-time; dispute cases are logged with a ticket/reference number instantly.

Regulatory timelines vary by request type. For failed ATM/POS transactions, reversals typically reflect within T+5 calendar days. Chargeback investigations for card transactions often complete within 30–45 days, depending on merchant response cycles. For net banking unlocks or profile updates completed via the call center after verification, changes reflect immediately or within 1 business day.

Escalation Matrix and Complaint Tracking

If your issue isn’t resolved satisfactorily on the first call, ask the agent for a Service Request (SR) or Complaint Ticket number and the expected resolution time. Keep this reference for follow-up. You can track status by calling the same helplines or by checking the “Grievances/Contact Us” section on the official website.

Escalation levels generally follow three tiers: (1) Branch or Contact Centre Resolution, (2) Regional Office/Nodal Officer escalation if not resolved within the stated TAT, and (3) Principal Nodal Officer/Head Office for complex or delayed cases. If your complaint remains unresolved beyond 30 days, or you’re dissatisfied with the outcome, you can escalate to the Reserve Bank of India under the Integrated Ombudsman Scheme (2021) via https://cms.rbi.org.in. Retain all call logs, SMS, and emails as supporting evidence.

Security and Verification: What to Share (and What Not to)

Union Bank agents will verify you using non-sensitive details (e.g., name, date of birth, partial account digits, recent transaction amounts). They will never ask for your full card number, CVV, OTP, net banking password, or UPI PIN. If anyone asks for these, disconnect immediately and report the incident to the helpline.

When calling from a public place, shield your screen and keypad. If you suspect account compromise (unknown OTPs, unsolicited UPI collect requests, or suspicious SMS links), immediately block channels via the helpline and change your credentials via the official website or app. Report fraud within the same day to maximize recovery chances; banks and networks prioritize disputes reported within T+1.

Special Cases: NRI, Corporate, and Digital Banking Issues

For NRI customers, toll-free Indian numbers may not work from abroad. Use the bank’s “Contact Us” page to find the current international contact options or to request a call-back after entering your registered details securely. If you’re temporarily in India, the standard 1800 numbers work from any domestic line or roaming Indian SIM.

Corporate and cash management services are typically routed to specialized desks after an initial IVR selection. Keep your Corporate ID and User ID handy. For UPI, IMPS, and net banking downtime or errors (e.g., “Txn Declined by Bank”), first check Union Bank’s official Twitter handle and site banners for outage updates before raising a ticket; it saves time if there’s an ongoing network maintenance window.

Head Office and Verified Online Touchpoints

Union Bank of India (Central Office) is headquartered at Union Bank Bhavan, 239, Vidhan Bhavan Marg, Nariman Point, Mumbai – 400021. Do not send debit/credit card numbers or PINs in postal mail or email. For document submissions (e.g., KYC), use branch counters or secure upload links provided within logged-in channels.

For online support, start with https://www.unionbankofindia.co.in and navigate to “Contact Us” or “Grievance Redressal.” For retail online banking, use https://www.unionbankonline.co.in. Bookmark these URLs to avoid phishing and always confirm the SSL lock and correct spelling before entering login information.

If You Meant a Different “Union Bank”

Several banks globally use the name “Union Bank.” The numbers above are for Union Bank of India. If you were looking for Union Bank (United States) or a different country’s institution, please consult that bank’s official site or card reverse-side for the correct customer care number. Using the wrong number can delay urgent actions like card blocking.

When in doubt, rely on what’s printed on your debit/credit card, your passbook/statement, or the bank’s official website domain in your country. Never trust numbers forwarded via messaging apps without verification.

Call Preparation Tips to Get Faster Resolution

• Keep these to hand: last 3 transactions, partial account number, date of birth, and registered mobile number. This speeds up verification.
• Take note of the SR/ticket number and the agent’s first name and time of call. If you need to escalate, these details help.
• For dispute/chargeback, note the exact transaction amount, date, time, merchant name, and channel (ATM/POS/UPI/Online).
• If you changed your phone or SIM recently, ensure your number is updated with the bank before using missed-call services.

Using the correct helpline and sharing only the right information ensures quick, secure resolutions. If you experience persistent issues reaching the toll-free lines during peak hours, try again in a non-peak window, or use the website to raise a service request and obtain a written trail alongside your call record.
