Bank Communication: Clear and prompt communication between your old and new banks is essential. Delays can occur if there are issues with verifying your information.

Pending Transactions: If you have pending transactions, it's important to complete them before initiating the routing number change. These transactions can influence the timing.

Update Requests: You'll need to update your routing number with any entities that conduct transactions with your account, such as your employer or service providers.

Processing Time: The actual processing time can vary. Some banks might make the change within a week, while others might take up to a few weeks.
