CC may refer to any of the following:

1. Short for carbon copy or courtesy copy, CC is a copy of an e-mail to be shared but requires no reply or action. For example, it is not uncommon for an employee who is sending an important message to other employees to also CC their manager or boss to help keep them up-to-date.

Writing an e-mail message

For anyone not familiar with the term "Carbon Copy," this term is derived from carbon paper that allows you to make a copy of another piece of paper. For example, if you have ever written a check the piece of paper behind the check is a carbon copy of the check that makes a duplicate copy of the check.

What should I put in an e-mail CC field?

Unless you plan on sending a carbon copy of the e-mail to someone else, the CC field can be left blank.

Do I reply to an e-mail if I'm in the CC field?

Generally speaking, no, you should not reply to an e-mail if you're e-mail address is in the CC field. Your e-mail address should only be in the CC field because the original sender wants to keep you in the loop of what is being discussed in the e-mail but does not require a reply.


If you want everyone to respond to an e-mail keep their address in the To field, which supports multiple e-mail addresses.

2. When referring to the mouse or mouse cursor, CC is short for Cursor Control. Cursor Control describes the ability to move the cursor using the arrow keys.

3. When referring to a Linux and Unix command, cc is a C compiler command. For additional information about the cc command, see our Linux and Unix cc command guide.

4. CC is an abbreviation for Creative Commons.

5. With a shortcut, C-c refers to the Ctrl+C shortcut key.
