Only federal users with permissions within the Contract Opportunity domain can delete a notice. Once an opportunity is deleted, it cannot be reactivated. 
 

To delete a notice:

1. 1. Log in to SAM.gov and go to your Workspace.
   2. Locate the Contract Opportunities widget.
       
      
       
   3. Find the notice you need to delete. 
   4. From there, locate the Actions menu and select Inactive to make the opportunity inactive.

That notice is now in archives. If contractors have signed up in SAM.gov to follow the solicitation, they will receive a notification whenever a notice has been deleted.
