Protecting You from Fraud with IDCheck

Posted on April 29th, 2025

General

Starting May 1, 2025, when you travel outside of Illinois and utilize our CO-OP Shared branching network, you will now be asked to verify your identity using IDCheck.

IDCheck verifies your identity in just a few simple steps to better protect you from identity theft, fraud and financial loss.

It allows a teller to identify and authenticate any members with out-of-state IDs in the branch through a QR code and one-time passcode multifactor authentication verification.

Upon arrival to the out-of-state Shared Branch credit union location, you will be asked to do the following:

Step 1: Scan the QR code located in the branch or visit verify.coop.org.

Step 2: Select “NuMark Credit Union” from the drop-down list.

Step 3: Enter your member number and the last 4 digits of your social security number.

Step 4: Upload a photo of your ID and take a selfie. Tip: Save your validation for an even quicker experience next time!

Step 5: Show your one-time passcode to the teller at the Shared Branch location. Passcode will be valid for 20 minutes.

IDCheck will be used for loan payments, cashier’s checks, deposits, withdrawals, transfers and account inquiries.

There are some Illinois credit unions that are starting to implement IDCheck for ALL of their Shared Branching users. You could be asked to do this the next time you visit an in-state location as well.

Visit verify.coop.org next time you’re in a Shared Branch to get started.
