What is my Alliant membership number?

Your membership number is a 10-digit secure identifier. You’ll need this to set up Alliant Online Banking, confirm your identity when calling, transfer money to other members, and for other banking needs.

You can view your member number in Alliant Online Banking. Select “Membership Number” in the blue toolbar near the top of the page. You can also find your member number in the Alliant mobile app or at the top of your most recent Alliant statement under the Account No. header.

Please note that your membership number should not be used to transfer funds or make deposits or payments. Instead, use the account number for the Alliant account you’re looking to transfer money in or out of.
