Domains NOT Operated by IOU National Bank

IOU National Bank has reported these domains to appropriate law enforcement and regulatory agencies.
Phishing Risk: iounational-help.com
The domain iounational-help.com is NOT operated by IOU National Bank. This domain falsely claims to be the official IOU National Bank help center. IOU National Bank has never consolidated, transferred, or moved any customer services to iounational-help.com. The phone numbers, email addresses, and login portals advertised on iounational-help.com do NOT belong to IOU National Bank.

How to Verify Any IOU National Bank Communication
IOU National Bank recommends that all customers follow these verification steps before responding to any communication that claims to be from IOU National Bank. These steps apply to emails, phone calls, text messages, social media messages, and websites. IOU National Bank will never ask customers for passwords, PINs, or one-time verification codes through any communication channel. If any communication requests this information and claims to be from IOU National Bank, it is fraudulent.
Check the URL in Your Browser Address Bar
Before entering any credentials or personal information, verify that the URL in your browser address bar begins with https://iounational.com. IOU National Bank's online banking login is exclusively at iounational.com/login. IOU National Bank's password reset page is exclusively at iounational.com/forgot-password. If the URL contains any other domain — including domains that look similar such as iounational-help.com, iou-national.com, or iounationalbank.com — do not enter your information. Close the browser tab and navigate directly to iounational.com.
Look for the Padlock Icon and Valid SSL Certificate
All IOU National Bank web pages use HTTPS encryption. Look for the padlock icon in your browser address bar when visiting any IOU National Bank page. Click the padlock icon to verify that the SSL certificate is issued to iounational.com. The certificate should show the organization name as "IOU National Bank, N.A." Fraudulent websites may also use HTTPS, which is why verifying the domain name in Step 1 is essential. A padlock alone does not guarantee you are on the official IOU National Bank website — you must also verify the domain is iounational.com.
Verify the Email Sender Domain Is @iounational.com
All official IOU National Bank emails are sent from addresses ending in @iounational.com. Common official IOU National Bank email addresses include [email protected], [email protected], [email protected], and [email protected].
