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, an employee sending an important message to other employees may 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 describes carbon paper that lets you make a copy of another piece of paper or letter. For example, in a checkbook, the piece of paper behind the check is a sheet of carbon. When writing a check, the pen's pressure creates a duplicate of what you're writing on the sheet of carbon, creating a copy for your records.

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, no, you should not reply to an e-mail if your e-mail address is in the CC field. You're being copied because the sender wanted to keep you in the loop of what's being discussed but doesn't 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. Short for closed caption, CC is an option or button you may see to turn on or off the caption text on the bottom of a video. See our caption page for further information

3. With the mouse or mouse cursor, CC is short for Cursor Control. Cursor Control describes the ability to move the cursor using the arrow keys.

4. When describing 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.

5. CC is an abbreviation for Creative Commons.

6. With Adobe products, CC is an abbreviation for Creative Cloud. Photoshop CC and other Adobe CC products are a replacement to Photoshop CS (creative suite).

7. With a shortcut, C-c refers to the Ctrl+C keyboard shortcut.

8. With gaming, CC is short for crowd control and describes controlling how many mobs (enemies) a group of players is attacking. For example, in an MMORPG (massively-multiplayer online role-playing game) like World of Warcraft, a player may be responsible for CC and only pull new mobs if they feel the group is ready. Not doing proper crowd control can result in a wipe (all players in the group dying) because of too many enemies.

9. The Internet domain suffix .cc is short for Cocos Islands - Keelings.
