Here is the text from IRS
A15. A valid SSN for a Payment is one that is valid for employment and is issued by the SSA before the due date of your 2019 tax return (including the filing deadline postponement to July 15 and an extension to October 15 if you request it) or your 2018 tax return (including extensions) if you haven’t filed your 2019 tax return.
Emphasize on the word “OR”
