Indian Overseas Bank BSR Codes — All Branches by State

Indian Overseas Bank BSR Codes — Complete Branch Directory

Indian Overseas Bank is one of India's major banks with 3,259 branches spread across 34 states and union territories, all registered in the Reserve Bank of India's Basic Statistical Return (BSR) database. Every Indian Overseas Bank branch that is authorised to accept direct tax deposits has a unique 7-digit BSR code — the mandatory identifier required for TDS challan filing, Form 16 generation, and Form 26AS tax credit matching. BankZop's Indian Overseas Bank BSR directory covers all active branches across India, sourced from official RBI records and updated regularly.

You need the Indian Overseas Bank BSR code of a specific branch whenever you deposit TDS at that branch and need to quote the Challan Identification Number (CIN) in your TDS returns. This page lets you drill down by state, city, and branch to find the exact 7-digit BSR code in seconds.

What is the BSR Code for Indian Overseas Bank?

The BSR code for any Indian Overseas Bank branch is a 7-digit numeric code that uniquely identifies that branch within India's tax payment infrastructure. The first three digits of every Indian Overseas Bank BSR code identify the bank, and the final four digits identify the specific branch — making the full 7-digit code unique to that single Indian Overseas Bank location.

Unlike the IFSC code (which identifies a branch for NEFT, RTGS, and IMPS transfers) or the MICR code (which identifies a branch for cheque clearing), the BSR code is specifically used for the Income Tax ecosystem — TDS challans, advance tax deposits, and self-assessment tax payments.

How the Indian Overseas Bank BSR Code Is Structured

Every Indian Overseas Bank BSR code follows the standard 7-digit RBI format:

• Digits 1–3 (Bank Code): Always numeric — these three digits uniquely identify Indian Overseas Bank across the entire RBI tax payment network. All Indian Overseas Bank branches share the same 3-digit bank code prefix.
• Digits 4–7 (Branch Code): Four numeric digits that uniquely identify the specific Indian Overseas Bank branch. This is what differentiates one Indian Overseas Bank branch from another within the BSR system.

Always enter the full 7 digits when filing on the Income Tax e-Filing portal. A common error is dropping leading zeros — for example, entering 20299 instead of 0020299 — which causes the challan to fail validation.

When You Need the Indian Overseas Bank BSR Code

TDS Challan Filing (Challan 280, 281, 282)

When you deposit TDS, advance tax, or self-assessment tax at a Indian Overseas Bank branch, the bank issues a challan counterfoil. This counterfoil carries the branch's 7-digit BSR code, the date of deposit, and the challan serial number — together forming the Challan Identification Number (CIN). The CIN is a mandatory field in every TDS return (Form 24Q, 26Q, 27Q, 27EQ) filed on the Income Tax e-Filing portal. An incorrect Indian Overseas Bank BSR code at this stage means the TDS credit will never match in Form 26AS.

Form 16 (TDS Certificate for Salaried Employees)

Employers who deduct TDS from salaries and deposit it at a Indian Overseas Bank branch must quote the branch's BSR code in their quarterly TDS returns (Form 24Q). This BSR code then flows into Form 16 Part A — the TDS certificate issued to employees. If the wrong Indian Overseas Bank BSR code is quoted in Form 24Q, the TRACES system cannot validate the challan, and the Form 16 generated will carry incorrect information — creating problems for employees during ITR filing.

Form 26AS (Annual Tax Credit Statement)

Form 26AS is the taxpayer's consolidated annual tax statement, auto-generated by the Income Tax Department from data filed by deductors. Each TDS entry in Form 26AS is matched using the BSR code + date of deposit + challan serial number combination. A wrong Indian Overseas Bank BSR code in the TDS return means the credit never appears in the taxpayer's 26AS — causing refund delays and potential demand notices even though the tax was actually paid.

TDS Challan Correction via TRACES

If you discover an incorrect Indian Overseas Bank BSR code has been filed in a TDS return, you can submit a correction request through the TRACES portal (tdscpc.gov.in) or at the Indian Overseas Bank branch where the payment was made. However, corrections are subject to time limits and add administrative burden. Always verify the BSR code on BankZop before filing to avoid this.

Indian Overseas Bank BSR Code vs IFSC Code vs MICR Code

All three codes identify a Indian Overseas Bank branch but serve completely different systems:

Use BSR for TDS deposits and income tax compliance. Use Indian Overseas Bank IFSC codes for NEFT, RTGS, IMPS, and UPI transfers. Use Indian Overseas Bank MICR codes for cheques and NACH/ECS mandates.
