Frequently Asked Questions About American Savings Bank Routing Numbers

Why does American Savings Bank only operate in Hawaii?

American Savings Bank was founded in Hawaii in 1925 and has maintained its focus on serving the local island community for nearly a century. As a subsidiary of Hawaiian Electric Industries, the bank concentrates on providing comprehensive financial services tailored to Hawaii residents and businesses. This local focus allows ASB to offer extended banking hours, including evenings and weekends, and maintain deep community connections through programs like Seeds of Service. The single routing number 321370765 serves all Hawaii locations efficiently.

How do I receive international wire transfers if American Savings Bank is not a SWIFT member?

American Savings Bank is not a direct SWIFT member, which means international wires require an extra step. For someone to send you money internationally, their bank must first wire funds to a U.S. intermediary bank such as Citibank New York, J.P. Morgan Chase New York, or Bank of America New York. The intermediary bank then forwards the funds to American Savings Bank in Hawaii using routing number 321370765 via Fedwire. You'll need to provide the sender with your account details, American Savings Bank's information, and instructions about using an intermediary bank.

What are American Savings Bank's wire transfer fees and cutoff times?

American Savings Bank charges $45 for outgoing domestic wires under $5,000, $75 for outgoing wires of $5,000 or more, and $13 for incoming wires. For same-day processing, you must submit wire requests in person at any branch before 11:00 AM HST on business days. International wires in U.S. currency have the same 11:00 AM HST cutoff, while international wires in foreign currency must be submitted by 2:00 PM HST. All wire requests must be submitted in person and cannot be sent by phone, mail, fax, or email for security purposes.

Can I use American Savings Bank's routing number for payments from the mainland United States?

Yes, you can receive ACH transfers and wire transfers from any U.S. financial institution using American Savings Bank's routing number 321370765. Many Hawaii residents and businesses receive payments from mainland companies, and the routing number works seamlessly for direct deposits, vendor payments, and other electronic transfers. The transaction processes just like any domestic U.S. transfer, though banks on the mainland should be aware that funds are going to Hawaii, which operates on Hawaii Standard Time and may affect same-day wire processing windows.

This service allows you to initiate wire transfers from your desktop or mobile devices, making it convenient to pay vendors and meet financial obligations without visiting a branch.
