I missed to send 1040-V with my check

I was in a hurry and did not write my SSN on the check.  Should I send another check w/ SSN and 1040-V attached?  

Also what's next if the IRS happens to cash both checks?

Thank you,  eugen

Checks and the paperwork that accompanies them (if at all) are separated in the processing. If you do not write your SSN on the check, the IRS cannot apply the payment. The IRS says to put your Social Security number on the memo line of a check when sending in a payment.

I would contact the IRS or stop payment on the check and send a new check.

Thanks very much @torobert222!  I think that I better call my bank to stop payment on my check, right?  + send the good one.

Thank you,  eugen

Yes, I would stop payment and send a new check although the IRS might charge you for the check being returned if they do try to cash it.
