Whenever money moves between banks, it needs a code to reach the right destination. In the US, that code is called a bank routing number. In India, domestic payments use the Indian Financial System Code (IFSC) code, while global transactions rely on the Society for Worldwide Interbank Financial Telecommunication (SWIFT) code. These identifiers make electronic transactions, bill payments, and direct deposits easier and error-free.
If you earn from clients in the US, or export goods and services abroad, you’ll often be asked for these codes. Knowing how they work helps you receive payments faster and stay compliant with banking rules. This guide breaks down each system clearly so you can manage international payments with confidence.
Key Takeaways
- Bank routing numbers are used only within the US for domestic transfers via ACH, wire and direct deposits.
- India does not use routing numbers; IFSC is used for domestic payments, while SWIFT is required for international transfers.
- Routing numbers, IFSC codes and SWIFT codes serve the same purpose of identifying banks to ensure transfers reach the correct destination.
- Understanding when to use each code helps businesses stay compliant and avoid transfer errors, especially while receiving money from the US.
- Tools like Razorpay MoneySaver Export Account simplify global payments by offering local-style collection accounts and automated compliance support.
What Is a Bank Routing Number?
A bank routing number also called the American Bankers Association (ABA) routing number or Routing Transit Number (RTN)is a nine-digit code used to identify a specific financial institution in the United States. It was introduced by the American Bankers Association in 1910 to streamline cheque processing. Today, it plays a crucial role in digital banking and electronic fund movement across the US.
Over time, banking shifted from paper-based to digital channels, but the purpose of routing numbers remained unchanged they still direct money accurately between banks and enable several essential functions, such as:
- Enables direct deposits of salaries and payments.
- Supports Automated Clearing House (ACH) transfers for automated payments and recurring billing.
- Used for online bill payments and subscription services.
- Ensures transactions reach the correct bank and branch, reducing payment failures.
- Helps verify the sender and receiver during electronic funds transfers.
Where to Find Your Bank Routing Number?
A bank routing number is used only for domestic transfers within the US. Indian businesses do not need it for receiving international payments, but it may appear in invoices, payment instructions, or contracts when dealing with US clients. In such cases, the sender in the US should know where to locate it.
A routing number can usually be found in the following places:
- On a Cheque: The routing number is generally the first nine digits printed at the bottom left corner.
- Online Banking: Most banks show it within the online banking portal or mobile app under Account Details or Account Information.
- Bank Statements: Monthly paper or digital statements often display the routing number along with account information.
- Official Bank Website: Some banks publish routing numbers on their website typically in the FAQ section or pages that explain direct deposit or wire transfer steps.
If the sender still cannot locate it, contacting the bank directly is the most reliable option to confirm the correct number and avoid payment errors.
Why Bank Routing Numbers Are Essential for Transactions
In the US financial system, bank routing numbers act as the foundation for every electronic transaction. They make sure that money moves to the correct financial institution and support smooth transfers between accounts. Without them, automated and large-value payments would face delays, errors, or even rejection.
Routing numbers are used for setting up and processing multiple types of transactions, such as:
- Direct Deposits: To receive salaries, tax refunds, or government benefits directly into a bank account.
- ACH Payments: For recurring bills, subscription charges, EMIs, or direct debit arrangements.
- Wire Transfers: To send large or time-sensitive payments quickly between banks.
- Online Bill Payments: Ensures that payments reach the correct bank account of the biller or service provider.
Entering the correct routing number is non-negotiable. A single error can delay payments, trigger reversals, or even send money to the wrong bank. Incorrect entries may also lead to additional fees and unnecessary follow-ups.
Bank Routing Numbers vs. Account Numbers
Both the bank routing number and account number are necessary for transactions, but they serve different purposes. Understanding the difference is essential when receiving payments, especially from US clients.
Key differences:
- Routing Number: Identifies the bank or branch within the US banking network. It is usually the same for all customers of that branch or region.
- Account Number: Identifies your specific bank account. It is unique to you, even if thousands of customers use the same bank.
Routing Number vs Account Number
| Feature | Bank Routing Number | Account Number |
| Purpose | Identifies the bank or branch | Identifies the customer’s account |
| Uniqueness | Same for many customers | Unique to each customer |
| Typical Length | 9 digits | 9–18 digits (varies by bank) |
| Used For | ACH, wire transfers, cheque processing | Deposits, withdrawals, transfers |
Think of the routing number as the city and state, and the account number as the street address. Both are required to ensure funds reach the exact destination without getting lost on the way.

Understanding IFSC and SWIFT Codes
There is no bank routing number in India. Unlike the US, India does not use ABA routing numbers for domestic transfers. Instead, two identifiers support money movement – the IFSC and the SWIFT code.
These codes help identify bank branches and institutions accurately, which is essential for smooth national and cross-border transactions.
- IFSC Code: The IFSC code is used for domestic transfers within India through NEFT, RTGS and IMPS. It is an 11-character code assigned to each bank branch.
- SWIFT Code: The SWIFT code in India is used only for international transfers. It identifies Indian banks globally when receiving payments from abroad.
What Is an IFSC Code?
The IFSC is an 11-character alphanumeric code assigned by the RBI to uniquely identify every bank branch that participates in electronic fund transfers. It serves as a digital locator within the Indian banking network and is essential for routing payments to the correct branch.
The IFSC code is mandatory for domestic transactions carried out via National Electronic Funds Transfer (NEFT), Real-Time Gross Settlement (RTGS) and Immediate Payment Service (IMPS). As these payment systems rely on accuracy, the IFSC plays a central role in identifying where the funds should be credited.
Structure of an IFSC code:
- First Four Characters: Alphabetic and represent the bank name (e.g., HDFC, SBIN).
- Fifth Character: Always ‘0’, reserved for future use.
- Last Six Characters: Used to identify the specific bank branch.
An IFSC code can be easily found on bank statements, cheque leaves, digital banking apps, or through official bank websites and the RBI’s branch locator tools.
What Is a SWIFT Code?
A SWIFT code, also known as a Bank Identifier Code (BIC) code, is a unique identification code used by banks across the world. It enables secure communication between financial institutions and helps verify the correct bank during an international transfer.
The code is made up of 8 or 11 alphanumeric characters and is required whenever funds move from one country to another. It ensures that the payment reaches the right recipient bank without delays or confusion.
Purpose and usage of a SWIFT code:
- Enables international transfers securely
- Identifies banks during cross-border payments
- Supports foreign currency transactions
- Helps receive export and service payments
- Connects banks under a standard global messaging system
Key Differences: IFSC, SWIFT, and ABA Routing Numbers
Different banking systems use different codes, and each serves a specific purpose. IFSC is used in India, ABA routing numbers are used in the US, and SWIFT codes are used worldwide for international payments. Knowing the difference helps ensure that transactions are sent through the right network and reach the correct bank every time.
Here are some key differences at a glance:
Geographical Scope: Each code operates within a defined region.
- ABA routing numbers are used exclusively within the United States.
- IFSC codes are limited to India and apply only to domestic transfers.
- SWIFT codes, on the other hand, function globally and enable international transactions between banks across different countries.
Purpose: The role of each code varies based on the type of payment.
- ABA routing numbers identify banks for domestic electronic payments within the US, covering ACH and wire transfers.
- IFSC codes pinpoint the specific bank branch in India for NEFT, RTGS, and IMPS transactions.
- SWIFT codes are used worldwide to identify banks for international wire transfers and secure interbank communication.
Structure: These codes differ not only in purpose but also in format.
- ABA routing numbers: 9-digit numeric format.
- IFSC codes: 11-character alphanumeric format.
- SWIFT codes: 8 or 11-character alphanumeric format.
IFSC vs SWIFT vs Routing Number
| Feature | ABA Routing Number | IFSC Code | SWIFT Code |
| Country of Use | United States | India | Global |
| Purpose | US domestic transfers | Indian domestic transfers | International transfers |
| Structure | 9 digits | 11 characters | 8 or 11 characters |
| Used For | ACH, wire transfers | NEFT, RTGS, IMPS | Cross-border payments |
Accuracy is essential for a smooth transfer process. Using the wrong code even a single character can result in failed transactions, delays, or additional charges.
