OFAC requires applicants to submit each individual application separately; regardless of if you are completing the online application or sending in a hard copy application through the mail. If an applicant is submitting a hard copy, each application should be in a separate envelope, accompanied by a separate cover letter. Applicants should not submit multiple applications in a single envelope with a single cover letter. If you submit applications in that manner, you may encounter some delay in the processing of your applications. Therefore, in order to prevent such delay, submit one application with one cover letter per envelope.
