There is no need to re-establish direct deposits or pre-authorized withdrawals; we processed all notifications on your behalf. Beginning now, please use the Marine Credit Union Routing Number, 275977489, and the full MICR account number when setting up new direct deposits or withdrawals. Please contact us for more information on establishing electronic transactions.

Product and Service Updates

Savings Accounts

All deposit accounts have been converted to Marine Credit Union accounts. If you did not already have a savings account, one was opened for you at no cost. With your new Marine Credit Union account, you receive competitive rates, easy access to your funds, access to new products, and a safe, simple banking experience.

Interest Bearing Checking

Your checking account was transitioned to our interest bearing checking account. Enjoy all the benefits of our regular checking account such as no monthly maintenance fees, four free boxes of checks annually, instant issue debit cards, free-e-statements, and more! Plus, you earn dividends when you maintain a minimum balance of $1,000.

Non-Interest Bearing Checking

Your checking account has been transitioned to our non interest bearing checking account. This account offers all the essentials with no monthly maintenance fees, no minimum balance, up to four free boxes of checks annually, free e-statements, instant issue debit cards, and more!


We have sent you a free box of checks at no cost to you. These checks were mailed to the address listed on your account and includes your new MICR number and routing number.

Debit Cards

You were sent a Marine debit card in the mail with a new look, card number, and PIN (Personal Identification Number). With your Marine debit card, you will enjoy unlimited free transactions at Marine Credit Union ATMs, up to five free transactions per month at non-Marine Credit Union ATMs, and no monthly or annual fees. Your debit card is equipped with EMV technology to provide an additional layer of security for your everyday purchases, comes with free fraud monitoring and protection, and features free debit card controls through Mobile Banking.

IRA (Individual Retirement Account)

IRA Certificate of Deposits will continue to earn interest at the rate contracted with Old National Bank until the maturity date. If renewed, they will renew at Marine’s rates. In November, you will receive a mailing related to your IRA requiring signatures to update your IRA Custodian to Marine Credit Union.

Certificate of Deposit (CD)

CDs will continue to earn interest at the rate contracted with Old National Bank until the maturity date. If renewed, they will renew at Marine’s rates.
