FAQs on Indian Overseas Bank Customer Care

1) What are the balance enquiry or missed-call banking numbers for Indian Overseas Bank?

Answer: Indian Overseas Bank provides missed-call banking facilities that allow customers to check their account balance or receive a mini statement. This service works only when the call is made from the mobile number registered with the bank. Once a missed call is given to the designated IOB number, the bank automatically sends an SMS containing the balance or recent transaction details. This feature is mainly used for quick balance checks without internet access.

2) How is Indian Overseas Bank in terms of overall customer service?

Answer: Indian Overseas Bank, being a public sector bank, generally offers stable and reliable basic banking services such as savings accounts, deposits, and remittances. Customer experiences often vary by branch, with some users finding services satisfactory for routine banking, while others feel service speed and digital experience may lag behind private banks. The bank is usually preferred for its lower charges and traditional banking support rather than premium or fast-paced services.

3) What should I do if my Indian Overseas Bank account is frozen?

Answer: If an Indian Overseas Bank account is frozen, it is usually due to reasons such as incomplete KYC, suspicious transactions, legal instructions, or compliance requirements. The account holder should immediately contact their home branch or customer care to understand the exact reason for the freeze. In most cases, submitting updated KYC documents or clarifying transaction details resolves the issue. If the freeze is due to a legal or enforcement directive, the bank may lift it only after receiving clearance from the concerned authority.

4) How can I file or email a complaint against Indian Overseas Bank?

Answer: Indian Overseas Bank allows customers to raise complaints through multiple official channels, including email, customer care numbers, online grievance portals, and branch visits. When submitting a complaint, customers should clearly mention their name, account number, registered mobile number, branch details, and a clear description of the issue. Supporting documents, if any, should also be attached. Complaints are generally acknowledged with a reference number for follow-up.

5) How can I register my mobile number with Indian Overseas Bank?

Answer: To register a mobile number with Indian Overseas Bank, customers usually need to visit their home branch in person. The process involves submitting a mobile number registration or SMS banking form along with valid identity proof. After verification by the bank, the mobile number is linked to the account. Once registered, customers can access SMS alerts, missed-call banking services, OTP-based transactions, and mobile banking features.

6) How can I get a bank statement from Indian Overseas Bank?

Answer: Indian Overseas Bank customers can obtain their bank statements through multiple methods. Statements can be downloaded via net banking or the mobile banking app, requested at the branch for a specific period, or obtained as a mini statement through ATM or SMS services. Customers may also request printed statements from the branch, and in some cases, digital statements can be emailed if the email ID is registered with the bank.
