High-Priority Items

  • Update Account and Routing Number

    CU1 will do our best to clear transactions that use your ICCU account and routing number for up to six months; however, we recommend updating everything as soon as possible to your new CU1 information.

    If you have any automatic debits or credits to your ICCU account, you will need to advise each business of your new Credit Union 1 account number and CU1’s Routing & Transit #: 271188081.

    To find your account number in Digital Banking, log in, select the account tile, and use the number at the top—excluding the last four digits.

  • Register for Digital Banking

    CU1's Digital and Mobile Banking is a seamless way to manage your accounts on your schedule. Pay bills, send money, track spending, manage your debit cards, monitor your credit, and more in Digital Banking. Register Here.

    Paper statement fees will be waived through August 31, 2025. If you are not enrolled in eDocuments after this date, you will be charged a $5.00 monthly statement fee. Set up eStatements by enrolling in eDocuments through Digital Banking.

    Follow these step-by-step instructions to learn how to enroll in eDocuments.

  • Verify Payroll

    Every effort was made to ensure payroll deposits and payroll distributions were converted properly. While there was no action required on your part for this transition, we recommend that you verify your payroll deposit and/or payroll distribution through Digital Banking with your first payroll.

Consumer Loans

Consumer Loans

 

Members who have a mortgage, home equity loan, or auto loan were converted to a matching or similar product in the CU1 system. The rate and term for each of these products will remain the same as originally contracted for the remaining term of the agreement.

Payment Changes

Several types of automatic payments—including internal transfers, recurring payments set up in Digital Banking, and external bill pay—did not carry over with the conversion. You will need to set up these payments again within CU1 Digital Banking.

If your loan payment was set up as an ACH (or a payment that makes a direct withdrawal from your bank account using your account number and routing number), any existing loan payments will clear. CU1 will do our best to clear transactions that use your ICCU account and routing number for up to six months. However, your ICCU account and routing number will no longer be valid after six months, and we recommend proactively updating everything to your new CU1 account and routing number as soon as possible to avoid the need for future changes.
