Account vs Routing Number
In the United States, the bank code for financial transactions combines a routing number and a bank account number. The external bank identification routing number and bank account number are printed in MICR ink on the bottom of each check, with the routing number to the left of the bank account number.
Example of account and routing bank code numbers:
The check number is to the right of the routing number and bank account number. MICR is magnetic ink character recognition, used by computers to automatically read numbers.
The routing number is also printed on the top right of the check, in a different format shown as a fraction. The fraction format is used as a backup number when MICR printing can’t be read.
The internal routing number for a bank on a deposit slip is also printed in MICR as a different number.
IBAN
An IBAN (international bank account number) is a standard format bank code of up to 32 alphanumerics used internationally (but not in the U.S. or Canada) to identify a foreign bank account and facilitate wire transfers and interbank transactions, including cross-border payments. The IBAN number includes a country code, two check digits, a bank identifier code, a branch code, and a bank account number.
Countries using IBAN include all EU countries, the UK, the Middle East, Africa, Pakistan, Latin America, and Caribbean countries.
The IBAN-using countries list, which may not be all-inclusive, includes the following:
- European (EU) countries
- United Kingdom (UK)

SWIFT Code
A SWIFT code is used worldwide for international money transfers between banks. The SWIFT code, or Bank Identifier Code (BIC), is an 8- to 11-digit code that identifies the bank, country, and the bank’s head office location, and optionally a specific branch. SWIFT is the registrar and administrator of SWIFT codes, which are created in accordance with ISO standards.
CLABE
In Mexico, CLABE (Clave Bancaria Estandarizada), which translates to standardized bank code or standardized bank cipher, is used for 18-digit Mexican bank account numbers. The CLABE is used for banking transactions, including bank transfers.
Sort Code
The Sort code is used in the UK and Ireland to identify the location of a bank account. Sort codes are 6 digits, written as three pairs of 2-digit numbers separated by hyphens. The Irish sort code, also known as the National Sort Code (NSC), begins with 9.
The sort code is part of the IBAN used for international bank transfers.
BSB (in Australia)
The BSB (Branch State Bank) code is used as a bank branch identifier in Australia. The BSB code consists of 6 digits, with the first 2 or 3 digits for branch identification. In Australia, international bank transfers use a BSB, account number, and SWIFT code (the same as a BIC code) for processing through the SWIFT network.
The BSB code, the location code for a specific bank branch, is on a bank statement and online banking account. The BSB number can be found by searching a BSB branch locator on your bank’s website or another online BSB checker tool.
New Zealand BSB/Clearing Code
New Zealand uses its own six-digit BSB bank code to identify a bank (first two digits) and specific branch location (last four digits) of a financial institution in that country. To make a wire transfer, you also need the seven-digit account number and a two- or three-digit suffix.
IFSC (in India)
In India, the IFSC (Indian Financial System Code) is used as a bank code for domestic interbank transfers and for transferring foreign funds to Indian bank accounts. IFSC is an 11-digit alphanumeric code used for electronic fund transfers.
MICR Code (in India)
Besides the IFSC, India also uses a MICR code for check processing through the Electronic Clearing System. The MICR code consists of three 3-digit codes: City Code, Bank Code, and Branch Code, totaling 9 digits. MICR is magnetic ink character recognition printing on checks for automatic electronic reading.
Hong Kong Bank Code
The Hong Kong bank code is a three-digit code used only for domestic bank account transactions within Hong Kong to identify the bank name. It’s combined with the branch code and bank account number to make bank transfers.
Hong Kong also uses SWIFT codes for overseas bank transfers.
Zengin Code (in Japan)
The Zengin Code used in Japan for domestic transfers consists of 7 digits, including a 4-digit bank code and a 3-digit branch code. Zengin Code is also used for PayPal and Google AdSense online payment transactions.
The Role of Bank Codes in Global Payments
Bank codes, such as SWIFT, IBAN, and ABA, are essential for simplifying global payments by standardizing bank routing and account information for domestic and international cross-border payments.
The Value of Global Cross-Border Payments and Initiatives
In his May 6, 2025, keynote at the Asian Development Bank (ADB) Annual Meeting, Fabio Banetta stated that the global cross-border payments market reached $190 trillion in 2024 and is projected to exceed $300 trillion in the next 5–10 years.
Banetta also highlighted Italy’s 2024 objectives for enhancing cross-border payments, focusing on the creation of bilateral interlinking arrangements between payment systems, a key initiative under the BIS Roadmap.
The Bank for International Settlements (BIS)—which supports global monetary and financial stability through international cooperation—has been instrumental in driving these improvements to modernize global payment networks.
ISO 20022 Adoption
For transactions using the SWIFT messaging system, the MT/ ISO 20022 standard coexistence period for cross-border payment instructions ended on 22 November 2025, with additional milestones continuing into 2026. The ISO 20022 unified global payment standard modernizes financial transactions through enhanced data exchange.
Organizations, including financial institutions with BICs for SWIFT transactions and FedNow, will leverage ISO 20022 to streamline processes. Corporations, market infrastructures, and securities market participants may also adopt ISO 20022 while retaining ISO 15022.
How Automation Streamlines Global Payments
Automation technology plays a crucial role in simplifying global payments by efficiently managing complex processes. With automated systems like Tipalti, businesses can streamline payee and supplier onboarding through self-service portals that securely collect contact information, preferred payment methods (including bank codes), and necessary tax forms before initiating payments.
Tipalti enhances compliance by validating bank routing details—such as SWIFT and IBAN codes—to reduce errors and ensure accuracy. Additionally, global regulatory checks, such as screening against OFAC blacklists based on the payee’s country and payment method, are seamlessly integrated into payment workflows, minimizing risk and maintaining compliance.
As global commerce continues to expand, mass payments automation technology remains essential for efficient, secure, and compliant cross-border transactions.
Eliminate errors in global payment details
Incorrect bank codes can lead to failed payments, delays, and added costs. Tipalti automatically validates banking information—including SWIFT, IBAN, and ABA details—to help ensure accurate, compliant global payments.
Bank Code FAQs
These FAQs answer more questions about the meaning of bank codes.
What is an ABA Number?
An ABA number is a nine-digit routing number or routing transit number (RTN) used to identify banks and branches in the United States in a standard format defined by the American Bankers Association.
How Do You Find an Example Bank Code Routing Number in the U.S.?
To find a bank code in the U.S., refer to your bank account statement, mobile banking app, or the bank’s lookup page for routing numbers. For example, you can find the Chase routing number bank code for your area, which may vary by state or region in the United States, by logging on and entering the last four digits of your bank account.
Are SWIFT Code and BIC the Same?
Yes. The SWIFT code standard format is specified in ISO 9362 as a BIC. International bank transfers go through the SWIFT network.
Where Do I Get a SWIFT/BIC Code?
The SWIFT network is a registry that administers each BIC code specified in ISO 9362. Besides the SWIFT code, people also refer to the BIC code as the bank identifier code, bank identification code, business party identifier, and business identifier code.
What are the SubCodes Within a SWIFT Code or BIC Code?
The eight to 11-character alphanumeric code for SWIFT/BIC has four parts, including the optional branch code:
1. Bank code (four letters) specifying the bank name
2. Country code (two letters)
3. Location code (two letters or digits ) to identify the bank head office
4. Branch code (three digits) for a particular bank branch location or XXX for the head office) – optional
Does the U.S. use the SWIFT Code (BIC)?
Although the U.S. has its own ABA routing numbers for bank codes, SWIFT codes are used in the U.S. to send international money transfers via the SWIFT messaging network.
Do I need a bank code for wire transfers?
Yes. You need a bank code for wire transfers. U.S. domestic wire transfers require an ABA code. International wire transfers use SWIFT, IBAN, or specific country codes, such as IFSC in India or routing/transit numbers in Canada.
Can I use an IBAN and a SWIFT code together?
Yes, IBAN and SWIFT codes work together in international banking. An IBAN is for the bank account, and a SWIFT code is a bank or branch identifier.
