Merger FAQs for IVCU Members

  • Your accounts will continue to be federally insured just as they are today through the National Credit Union Share Insurance Fund, which is backed by the full faith and credit of the U.S. Government and managed by the National Credit Union Administration (NCUA).

  • You can continue to use IVCU branch. We cannot begin integrating the operations of the two credit unions until after the system conversion date of date January 31, 2027. IVCU members will be notified as soon as the additional branches are connected.

  • Credit Union 1 ATMs are available for anyone to use; however, we cannot begin integrating the operations of the two credit unions until after the system conversion date of date January 31, 2027, so you may incur a fee until that time. Once the merger is effective, you will have access to all Credit Union 1 ATMs at no charge along with more than 130,000 CO-OP surcharge-free ATMs nationwide through the Allpoint, CO-OP, and MoneyPass networks.

  • Yes, your account number will change on after the system conversion date. Be sure to update any external parties—such as your employer (for payroll), service providers (for ACH transactions), or lenders—with your new Credit Union 1 (CU1) routing and account numbers.

    To find your new account number after the system conversion date:

    1. Log in to Digital Banking.
    2. Go to the ‘Menu’, then select ‘Services’, followed by ‘Setup Direct Deposits’.
    3. Here, you can use ClickSwitch to update your direct deposits and ACH transactions, or scroll down to download a PDF with your account details.
  • Yes, the routing number will also change after the system conversion date. The new CU1 routing number is #271188081. You can find it in Digital Banking by scrolling to the Move Money tile, or at the bottom of the cu1.com website.

  • Yes, but not until the system conversion.

    • Continue using IVCU online/mobile banking through January 31, 2027.
    • After the system conversion date, switch to Credit Union 1’s Digital Banking platform and mobile app, offering convenient access anytime, anywhere. You can register for Digital Banking beginning after the system conversion date.
  • Yes. Continue using your Illinois Valley debit card. Communications will be sent out closer to the operational date of when you will begin using your new Credit Union 1 debit card.

  • Until the system conversion date January 31, 2027, none of your account terms will change. Whether or not they will change after the system conversion date depends on the type of account.

    Loans | Your existing loan contract will remain in effect until the loan is paid off.

    Share Certificates | The terms of your existing share certificate will remain in effect until the maturity date.

    Savings & Checking | Rates and terms on these accounts are subject to change at the time of the merger date. You will receive a CU1 Membership Agreement and Account Disclosures before the merger date.

    Credit Cards | Credit Union 1 offers an array of credit card options with competitive rates and exciting rewards. More information will be provided after the system conversion date of date January 31, 2027.

Access 130,000 ATMs Nationwide: Surcharge-free options wherever you go.
