If the wrong electronic account number was submitted for direct deposit of your refund is the check then sent to you in the mail?

If the wrong electronic account

number is submitted and it's an invalid number so it's rejected,

the IRS issues you a paper check. If the wrong number is submitted

and it's a valid number (it just isn't your account number), then

the IRS has no way of knowing that, because it doesn't come back to

them as rejected. In that case, it isn't the IRS' responsibility to

track down the wrong account number and retrieve the deposit. It's

your responsibility to talk to your bank so they can identify,

according to the incorrect but valid routing code and account

number, the bank and account that have your deposit.
