Working with international clients but getting lost in the maze of banking codes? 

If you've ever been asked for your ABA number while setting up payment details, you're not alone. ABA stands for American Bankers Association, and these numbers are essential for receiving bill payments into your U.S. bank account or other financial institution. Think of it as your bank's unique address in the American banking system.

In this guide, we'll break down everything you need to know about ABA numbers – from what they are and where to find them to how they work in getting your hard-earned money safely into your account.

What is an ABA Number? 

An ABA or routing number is your bank's identification code in the United States. Every U.S. bank has at least one of these nine-digit numbers, which you've probably spotted at the bottom of your checks.

It is like a postal digit code for your bank – it helps other banks know exactly where to send money when someone's making a payment to your account number. You'll often see it referred to as a routing number, though some people still call it a check routing number since it's printed on paper checks.

Your bank might have several different ABA numbers, which can initially seem confusing. Here's why: Large banks often have multiple ABA numbers because they operate across different regions and handle various electronic transactions. Think of it like having different phone extensions for different departments in a company.

For instance:

  • If you opened your account in New York, you'll have a different ABA number than someone who opened their account in California, even at the same bank
  • Your bank might use one ABA number for paper checks and direct deposits but a different one for wire and electronic funds transfers
  • If your bank merges with another bank, they might maintain separate ABA numbers for different branches. 

This is why it's important to always check with your bank about which ABA number to use for your specific transaction. Using the wrong one could delay your payment or cause rejection, especially for wire transfers.

This clarity around which number to use becomes especially important when setting up payment details with clients or employers, so it's worth double-checking with your bank about which number to use for different types of transactions.

Anatomy of an ABA code 

Let's break down what those nine digits in your ABA number mean. While it might look like a random string of numbers, each digit serves a specific purpose in ensuring your money gets to the right place.

To make things easier, we will explain with an example. 

When you look at ABA number 026009593, it's like a detailed address for your bank:

  • The first two digits (02) tell us this bank is in the Federal Reserve Bank of New York's territory. Think of this as identifying which region of the country your bank is in.
  • The next two digits (60) point to the Federal Reserve processing center that handles this bank's transactions.
  • The middle four digits (0959) are like your bank's unique ID number – they tell the system exactly which bank should receive the money.
  • The final digit (3) acts as a security check. Banks use this number to verify that all the other digits were entered correctly, helping prevent errors in your electronic funds transfer.

Let's look at another ABA number: 121000358

  • The first two digits (12) indicate this bank is in the San Francisco Federal Reserve district
  • The next two digits (10) represent the specific Federal Reserve processing center in that district
  • The middle four digits (0035) are the unique identifier assigned to this specific bank
  • The final digit (8) is the security check digit that helps verify all other numbers were entered correctly

This organized structure helps route your money accurately through the U.S. banking system, ensuring it reaches the correct bank in the San Francisco region. Understanding these patterns can help verify whether you use the correct ABA number for your transactions.

Understanding this structure can be helpful when verifying your banking details with clients – you can quickly check if the number they're using matches your bank's region and follows this pattern.

Is the ABA code the same as the SWIFT Code? 

If you're handling domestic and international transactions, you'll come across two types of bank codes: ABA numbers and SWIFT codes. While they might seem similar initially, they serve different purposes in getting your money where it needs to go.

ABA number is like your bank's domestic address – it's only used for transactions within the United States. It's a straightforward 9-digit number that tells other U.S. banks exactly where to send your money. You'll use this when setting up direct deposits or receiving electronic payments from U.S. clients.

SWIFT codes, on the other hand, are your bank's international address. When clients from overseas want to send you money, they'll need your bank's SWIFT code. These codes look slightly different – they use letters and numbers (like CHASUS33) and help banks worldwide identify each other for international transfers.

It's worth understanding both codes, especially when receiving international payments. As an Indian business or freelancer receiving payments from U.S. clients, you must share your bank's SWIFT code, not the ABA number. You're receiving an international wire transfer, and SWIFT codes are used for cross-border payments.

Remember: ABA numbers are only used for electronic transfers within the U.S. banking system. When receiving payments from U.S. clients using your Indian bank account number, always provide your bank's SWIFT code to ensure your payment arrives safely and efficiently .

📚Note: Using the wrong code might delay your payment or cause rejection, so always clarify with your client whether they're sending money domestically (ABA) or internationally (SWIFT). 

What is the ABA Routing Number Policy of India? 

As an Indian freelancer or business owner, you'll mainly work with two banking codes: IFSC codes for transfers within India, and SWIFT codes for receiving payments from U.S. clients. You won't need to worry about ABA numbers since they're only used for transfers within the U.S. banking system.

Like the U.S. banking system uses ABA numbers to route payments, Indian banks use IFSC codes. Think of it as India's equivalent of the ABA system – different code, same purpose. 

When receiving money from India, you must work with IFSC codes instead of ABA numbers.

This is a good reminder that different countries have their unique banking codes and systems:

So, if you're doing business internationally, you'll want to familiarize yourself with the banking codes used in your clients' countries to ensure smooth payment processing.
