Swift Code vs. ABA Number: What's the Difference?
By Janet White || Published on December 9, 2023
SWIFT Code refers to international identification code for banks in financial transactions. ABA Number refers to U.S.-specific bank routing number for domestic transactions.
Key Differences
A SWIFT code, also known as a Bank Identifier Code (BIC), is used in international bank transactions to identify specific banks globally. It is an 8-11 character long alphanumeric code. In contrast, an ABA number, commonly known as a routing number, is a 9-digit code used primarily in the United States for identifying financial institutions in domestic transactions.
The SWIFT code facilitates cross-border and international payments by providing a standard format for Business Identifier Codes. It is essential for wire transfers and international trade. On the other hand, the ABA number is crucial for domestic money transfers within the U.S., including direct deposits, bill payments, and check processing.
SWIFT codes are managed and issued by the Society for Worldwide Interbank Financial Telecommunication, ensuring uniformity in international finance. Conversely, ABA numbers are overseen by the American Bankers Association, reflecting their primary focus on the U.S. banking system.
SWIFT codes are required when sending money internationally, helping to reduce errors and ensure the funds reach the correct destination. The ABA number, however, is necessary for routing funds between U.S. banks, making it a key component of the national banking infrastructure.
SWIFT codes are integral to global financial communications, aiding in identifying banks internationally, while ABA numbers cater to the domestic needs of the U.S. banking system, identifying U.S. banks for local transactions.
