Digital Banking Registration

Your local branch team will assist with business Digital Banking registrations. You will receive an encrypted message detailing your first-time log-in instructions and temporary credentials. After receiving your encrypted first-time log-in instructions, please log in within 24 hours using the supplied temporary credentials. Upon logging in, you will be prompted to set a unique password and can update the username to your preferred username under settings.
Update Account and Routing Number

If you have any automatic debits or credits to your Great River 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.
Enroll in eDocuments to Receive eStatements

Paper statement fees will be waived through December 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.

Business Loans

Members loans were converted to a matching or similar product in the CU1 system. The rate, term, and monthly payment 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 Great River account and routing number for up to six months. However, your Great River 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.
