Top FAQs

What are your limits?

After account opening, transfers initiated through the Vio Bank External Transfer Service are limited to $25,000 per day and $100,000 per month. Vio Bank doesn't limit the amount of incoming and outgoing ACH transfers initiated by a third party transfer service or another financial institution, but such transfers are subject to the Funds Availability Policy in your Account Agreement and under applicable law.

Why do I need to have my forms notarized?

It is Vio Bank’s policy to require notarized forms when making changes to or performing transactions on your account to help ensure it is you requesting the change and not a fraudulent attempt to access or update your account.

How do I view my account number and routing number?

The Vio Bank routing number is 303087995. This routing number is also registered to MidFirst Bank since Vio Bank is a division of MidFirst Bank. You may view your whole account number by logging in to your online banking. Simply go to the Accounts tab on your Vio Bank online banking profile. Click the Online Documents link, and then select your last statement. The full account number will be viewable on your statement.

Can I add a POD (Payable on Death) beneficiary on my account?

Yes, you may add a POD beneficiary to your Vio Bank account by completing the Request to Add or Remove a POD (Payable on Death) Beneficiary. Once you have the completed form signed and notarized, you may submit the form to Vio Bank via email to customerservice@viobank.com, fax to 405.840.0862, or mail to Vio Bank, P. O. Box 76149, Oklahoma City, Oklahoma 73147.

When should I expect my ACH deposit to become available?

Vio Bank will typically place a hold on deposits for five business days, although some circumstances may necessitate a longer hold to ensure adequate funds and the safety of your account. During that period, you will see your deposit within Vio Online/Mobile Banking, but you won’t be able to transfer it out until the period ends. You will earn the full amount of interest for those days regardless of the length of the hold.
