Where to Find Your ASB Account Number
There are several reliable places to locate your American Savings Bank account number. Pick whichever is easiest for you right now.
On Your Checks
If you have ASB checks, look at the bottom row of numbers. Reading left to right, you will typically see the routing number first, then your account number, then the check number. If that layout is confusing, this guide to the account and routing number on a check breaks down each set of digits.
The routing number should read 321370765. Your account number is the set that follows it.
On Your Statement
Your account number is printed on your monthly statement, whether you get it by mail or view it online. Look in the account details or summary section near the top.
In Online and Mobile Banking
Log in to ASB's online banking or the mobile app, then open your account details. Your account number is listed there, and you can copy it directly for a deposit form.
By Phone
If you would rather ask a person, you can call ASB's Customer Banking Center. As of July 2026, the number is (808) 627-6900, or toll-free (800) 272-2566. You will need to verify your identity first.
Account Number vs. Routing Number
It is easy to mix these up, so here is the difference in plain terms.
The routing number, 321370765 for ASB in Hawaii, identifies the bank. It is always 9 digits and is public information. Your account number identifies your specific account and should be kept private. People often confuse the account number with the check number too, so it helps to know whether the checking number is the same as the account number.
For almost any setup, such as direct deposit, ACH transfers, or bill pay, you will provide both numbers together. Double check them before submitting, since a single wrong digit can misroute your money.
Using Your Numbers Safely
Once you have your account number, guard it like you would a password. Share it only for legitimate deposits or payments, and avoid sending it over unsecured email or text.
A few smart habits help. Turn on account alerts, review statements regularly, and confirm any request for your number is coming from a trusted source. If you spot activity you do not recognize, contact ASB right away.
Wire transfers sometimes use a different routing number than ACH, so if you are sending a wire transfer, confirm the correct one with the bank first.
Thinking About a Second or Backup Account?
Many people keep their main account at a local bank like ASB while adding a digital account for everyday spending, budgeting, or faster alerts. Having a backup account can also be handy for separating bills from savings, and it is easy to open a bank account online in a few minutes.
If that appeals to you, mobile-first accounts are worth a look. Current is an app-based account that shows your account and routing numbers instantly and sends real-time notifications on every transaction, which pairs nicely alongside a traditional bank.
