Please note that without the correct routing number AND account number together, your refund will not come via direct deposit. However, don't worry! You should receive notice from the IRS when they cannot complete the direct deposit and this notice will come via US Mail.  This notice will let you know that a paper check should arrive shortly there isn't a specific time window for how long this will take. Please see the following link for more info on the IRS notice you will receive: https://www.irs.gov/individuals/understanding-your-cp53a-notice
