Prepare for System Conversion

Prepare for the System Conversion

 
  • Update Contact Info

    To ensure you receive all important communications about your account and what this merger means to you, it is critical that we have the best contact information for you on file.

  • Print or Save Statements

    To prepare for the upcoming system conversion, we recommend printing or saving PDF versions of one year’s worth of statements for your records.

  • Adjust Bill Payments

    In order to complete the system conversion, Digital Banking and Bill Pay systems will be down for a short period of time. We recommend that you change any bill payments that are due during the conversion timeframe to ensure timely payment.

    • Reschedule the payment to process before the system conversion
    • Unschedule the payment and pay the bill using an alternate method.
  • Note Bill Pay Information

    Current Bill Pay users will not be automatically transferred over during the system conversion. Once the system conversion is complete, you will need to enroll in CU1’s Digital Banking and Online Bill Pay platform to setup all recurring transfers.

    Make note of your current payees: Company Name, Account Number, Address and Phone Number

Merger FAQs

 
  • 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 ICCU’s branch. We cannot begin integrating the operations of the two credit unions until after the system conversion date of date May 31, 2025. ICCU’s 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 May 31, 2025, 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 30,000 CO-OP surcharge-free ATMs nationwide.

  • Your account number will remain the same for the time being. More information will be provided after the system conversion date of date May 31, 2025.

  • Your routing number will remain the same for the time being. More information will be provided after the system conversion date of date May 31, 2025.

  • You will continue to use ICCU’s online/mobile banking until the system conversion date May 31, 2025. Once the conversion of systems occurs, you will then use Credit Union 1’s Digital Banking platform and highly rated mobile app. Banking anytime, anywhere has never been simpler.

  • You will continue to use ICCU’s debit card. ICCU members will be issued a Credit Union 1 Visa® Debit Card to use once the conversion of systems occurs.

  • Until the system conversion date May 31, 2025, 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 May 31, 2025.
