Hi! I understand you're trying to set up your Old National Bank account and need the customer service phone number without an extension. You can reach Old National's Client Care directly by calling 1-800-731-2265. This is their main customer service number and does not require an extension.

If you want, I can guide you on what details you might need handy when you call or help you with setting up your account online. Would you like me to assist you with that?

it's asking me for MY extension number, and I don't have one.

Thanks for clarifying! So the Old National Bank app is asking you to enter your extension number during account setup, but you don't have one. That sounds like a bit of a confusing prompt.

Sometimes, banking apps include an "extension" field to accommodate users who might be part of an organization or business with phone extensions. If you don’t have an extension, you can usually just leave that field blank or enter "0" or "none" when prompted.

Could you tell me exactly what the app allows there? For example, does it require a number or does it accept letters or being left empty? Also, are you setting up a personal account or a business account by any chance? This can help me guide you better.

Meanwhile, if the app won't accept leaving it blank or filling "none," we might try clearing the app cache or reinstalling the app as a next step. Let me know what you see!
