General Information:

Standards for transmission for most types of CUI are the same as for FOUO but some variance does exist. Therefore, specific requirements for certain CUI may need to be checked against applicable references to ensure proper means for transmission are used. 

For most CUI and FOUO specifically ensure the following standards are met: 
1. FOUO information and material may be transmitted via first class mail, parcel post, or, for bulk shipments, via fourth class mail. 

2. Electronic transmission of FOUO information, e.g., email, shall be by approved secure communications systems or systems utilizing other protective measures such as Public Key Infrastructure (PKI) or transport layer security (e.g., https). 

3. Use of wireless telephones (cellphones, wireless hand-held phones, Bluetooth, etc.) should be avoided when other options are available. 

4. Transmission of FOUO by facsimile machine (fax) is permitted; the sender is responsible for determining that appropriate protection will be available at the receiving location prior to transmission (e.g., machine attended by a person authorized to receive FOUO; fax located in a controlled government environment).
