Moving money within the U.S.? Grab the 9-digit ABA routing number. Sending cash overseas? HDFC’s SWIFT/BIC code is HDFCINBBXXX.
What’s Happening
When you shuffle money between banks—especially across borders—you’ll usually need two pieces of info: the ABA routing number and the SWIFT/BIC code. The ABA routing number is a nine-digit code that points U.S. banks to where your account was opened. You’ll find it on checks and in your online banking dashboard. The SWIFT/BIC code, though, is an 8–11 character alphanumeric string that identifies a specific bank worldwide. It’s the key for international payments so your money lands in the right place, even if the exact branch isn’t listed.
(Here’s the weird part: the U.S. is the only country that uses routing numbers for domestic transfers. Most other nations skip routing numbers entirely and just use SWIFT codes for international payments.) If you’re sending money from a U.S. account to an HDFC branch in India, for example, you’ll need both the recipient’s account number and HDFC’s SWIFT code—HDFCINBBXXX. This code works for every HDFC branch in India, so you don’t need a separate code for each location.
Step-by-Step Solution
Need to track down or use your routing number or SWIFT code? Here’s exactly how to do it.
- Locate your ABA routing number (domestic transfers):
- Flip over a physical check. The first nine digits in the bottom-left corner are your routing number.
- In online banking, head to Accounts > Account Details in the web portal or mobile app. Look for “Routing Number” or “ABA Number.”
- Dial HDFC customer service at 1-800-22-6789 (as of 2026) or swing by a branch.
- Find HDFC’s SWIFT/BIC code (international transfers):
- Log into your HDFC online banking. Go to Accounts > Account Statement. Your SWIFT/BIC code sits at the top of the statement.
- Peek at your monthly paper statement under the “Bank Details” section.
- Ring up HDFC customer support and ask for the SWIFT/BIC code for international transfers.
- Use the correct code when you start a transfer:
- For domestic ACH or direct deposit, type in your 9-digit ABA routing number.
- For international wire transfers, enter the recipient’s full account number, SWIFT code HDFCINBBXXX, and beneficiary details.
If This Didn’t Work
Still hitting a wall? Try these workarounds.
- Use an intermediary bank lookup tool. Sites like SWIFT.com or American Bankers Association let you search for routing numbers and SWIFT codes by bank name and location.
- Call your bank’s international desk directly. If you’re sending from a U.S. bank to HDFC, phone your bank’s wire transfer department and confirm the exact SWIFT code and any intermediary bank rules.
- Double-check the transaction type. Some U.S. banks use different routing numbers for domestic wires versus ACH transfers. Ask your bank which number applies to your specific transfer.
Prevention Tips
Before you hit send, make sure you’ve got the right code—otherwise your money might get lost in the shuffle.
- Save your routing and SWIFT codes securely. Tuck them into a password-protected note or encrypted file. Update them anytime you switch banks or move.
- Triple-check recipient details. A single typo in the SWIFT code or account number can send your funds down the wrong rabbit hole or cause painful delays. Confirm the details with a quick phone call before you submit the transfer.
- Use trusted transfer services. For international transfers, platforms like Wise, Remitly, or Western Union often auto-fill SWIFT codes and validate routing numbers, slashing the chance of human error.
- Keep bank contact info updated. Make sure your bank has your current phone number and email so they can ping you if a transfer looks shady or gets held up.
According to the Federal Reserve, routing numbers have been locked in since the mid-20th century and are managed by the American Bankers Association. As of 2026, over 26,000 unique routing numbers are in use across the U.S., each tied to a specific financial institution or branch.
The SWIFT network, launched in 1973, links more than 11,000 financial institutions in over 200 countries, including HDFC Bank in India, per the SWIFT organization. That means even when you use a single SWIFT code like HDFCINBBXXX, your transaction still finds its way to the right HDFC branch thanks to the account number you provide.
