Indian Overseas Bank Branch Timings and Contact Details

Indian Overseas Bank (IOB) is a major public-sector bank with branches across India and a wide range of digital services. Many routine transactions can be completed through Internet Banking, Mobile Banking, UPI and ATMs, but customers still need a branch for cash services, KYC, documents, locker access, account changes and loan-related work.

Knowing Indian Overseas Bank branch timings is particularly useful around Saturdays and holidays. The bank’s official locator currently lists 10:00 AM to 5:00 PM business hours for many branches and identifies the second and fourth Saturdays as holidays.

The official locator provides branch-specific hours, address, IFSC code, telephone number and current open or closed status. Customers with time-sensitive work should check the selected location before travelling.

Here is a practical guide to IOB branch timings, working days, lunch arrangements, customer-care numbers, card blocking, fraud reporting and grievance contacts.

Indian Overseas Bank Branch Timings – Quick Overview

The schedule reflects IOB’s current official website. Check the individual branch page for its latest hours and contact number.

What Are the Indian Overseas Bank Branch Timings?

Many Indian Overseas Bank branches currently list business hours of 10:00 AM to 5:00 PM on the bank’s official branch locator.

Official IOB pages for branches in Bhubaneswar, New Delhi, Ahmedabad, Navi Mumbai and Kerala display the same 10:00 AM to 5:00 PM Monday-to-Friday business window, along with branch phone and IFSC details.

Routine work can generally be planned within the displayed hours. For KYC, account opening, loan documentation or locker work, arriving well before closing is preferable.

For an urgent visit, use the hours and contact number shown for the exact branch in IOB’s locator.

Indian Overseas Bank Working Days

Indian Overseas Bank branches normally operate on regular weekdays, subject to applicable holidays.

IOB’s official branch pages state that the second and fourth Saturdays are holidays. For any other Saturday, confirm the branch timing through the locator or by phone.

Indian Overseas Bank Saturday Working Schedule

Based on the holiday information displayed on IOB’s official branch locator, the practical Saturday schedule is:

1st Saturday – Normally a working Saturday; verify the branch timing

2nd Saturday – Holiday

3rd Saturday – Normally a working Saturday; verify the branch timing

4th Saturday – Holiday

5th Saturday – Normally working when the month has one; verify the branch timing

IOB does not publish a separate nationwide Saturday-hours table on the pages reviewed, so verify the selected branch before travelling on a working Saturday.

Indian Overseas Bank Lunch Timings

Indian Overseas Bank does not publish one fixed nationwide lunch closure on the official branch pages reviewed.

The official locator shows a continuous 10:00 AM to 5:00 PM window for many branches without a separate lunch shutdown. Customers should not assume that every branch closes all counters during a fixed 1:00 PM to 2:00 PM period.

For work requiring a particular officer or detailed paperwork, an earlier visit is more practical.

Indian Overseas Bank Holidays

IOB’s official locator marks Sundays and the second and fourth Saturdays as closed days on the branch pages reviewed.

For other holidays, confirm the particular branch before visiting. The locator shows its current status and telephone number.

For deadline-based or document work, check the exact location before a holiday-period visit.

Do All Indian Overseas Bank Branches Have the Same Timings?

Many IOB branch pages currently show the same 10:00 AM to 5:00 PM schedule, but customers should still use the timing displayed for their exact branch.

The official locator provides location-specific address, IFSC, telephone and business-hour details, making it the better source for planning a visit.

For urgent work or a named officer, call the branch number shown on its official page.

Indian Overseas Bank Customer Care Numbers

IOB provides toll-free, overseas, NRI, digital-banking and grievance contacts for customers who may not need a branch visit.

Indian Overseas Bank Official Customer Care Numbers

The Reach Us page also publishes separate contacts for Mobile Banking, UPI, IMPS, RTGS/NEFT, Internet Banking, credit cards, pensions and retail banking.

Indian Overseas Bank ATM Card Blocking and Fraud Reporting

If a card or digital channel may be compromised, customers should act immediately rather than waiting for a branch to open.

IOB’s Customer Protection FAQ says Mobile Banking can block Debit Card and Mobile Banking channels, Internet Banking can block Debit Card and Internet Banking channels, BHIM IOB UPI can block UPI access, and the IOB Credit Card App or portal can be used for credit cards.

The bank identifies 1800 890 4445 and 1800 425 4445 as 24×7 numbers for blocking channels. Customers can also email cybercell@iob.in from the registered email address or approach a branch during working hours.

For cyber fraud, IOB lists 044-28584890 and cybercell@iob.in. Suspicious transactions should be reported quickly, and customers should never disclose PINs, CVVs, passwords or OTPs.

Indian Overseas Bank Customer Support and Email Channels

IOB publishes separate contacts for different customer-service issues.

For customer-service escalation, the bank lists 044-28519511 and gm-csd@iob.in. Other public grievances use 044-28591029 and csd@iobnet.co.in; ATM and Visa Debit Card contacts are separately listed on Reach Us.

Digital-banking complaints can be raised on 044-24371120, with separate official channels available for Mobile Banking, UPI, IMPS, NEFT/RTGS and Internet Banking.

Indian Overseas Bank Grievance Redressal

Indian Overseas Bank follows an internal grievance-redressal structure based on the nature and level of the issue.

The grievance policy makes the Branch Manager responsible for branch-level complaints. Escalated matters may move to the Regional Manager or Central Office department, while the Principal Nodal Officer and Customer Service Department oversee the system.

Keep the complaint reference for follow-up and check the Reach Us page for current nodal-officer details, as personnel can change.

Indian Overseas Bank WhatsApp Banking

Indian Overseas Bank announced WhatsApp Banking in July 2025.

IOB’s official branch-locator site includes a ‘WhatsApp Us’ link to 9677711234. Using the link on the bank’s own website helps avoid unverified numbers circulated elsewhere.

PINs, CVVs, passwords and OTPs should never be shared in a banking chat.

Services Available When Indian Overseas Bank Branches Are Closed

A closed branch does not stop all Indian Overseas Bank services.

IOB Internet Banking supports transfers, bill payments, deposits, tax payments, Debit Card controls, selected government-scheme services, statements and certificates. BHIM IOB UPI supports instant digital payments and transfers.

Internet Banking and Mobile Banking

BHIM IOB UPI

ATMs and Cash Deposit Machines where available

Fund transfers and bill payments

Debit Card controls through supported digital channels

Account statements and selected certificates

24×7 toll-free channel blocking for urgent security situations

Original documents, physical signatures, locker access and in-person verification still require an open branch.

Best Time to Visit an Indian Overseas Bank Branch

For routine work, the 10:00 AM to 5:00 PM window shown for many IOB branches is a useful guide.

For KYC, account opening, loan documents, lockers or officer-assisted services, reach well before closing.

Before an important Saturday or holiday-period visit, check the exact branch in IOB’s official locator and call the displayed number when necessary.
