As an AI language model, I am not directly connected with Capital One's policies and may not have access to their most recent information. However, as of my last knowledge update, Capital One has implemented some restrictions on cash deposits.
In most cases, you are allowed to deposit cash into your personal or business checking accounts at Capital One. However, there might be a few limitations on the amount you can deposit without prior notice or documentation. These limits may vary based on location and account type.
It's advisable to check Capital One's official website, contact their customer service, or visit a local branch to get the most accurate and up-to-date information on their policy regarding cash deposits.
