C/O: Care Of Definition

C/O, standing for 'Care Of', is a term used in postal and mailing contexts to send mail to an individual via another person or entity. This method ensures the intended recipient receives the mail even if they are not directly accessible.

“Care of (C/O)” is a widely utilized mailing and communication term, employed to send mail to an individual through another person or entity. The “C/O” symbol acts as an intermediary address, ensuring that the letter or package reaches its intended recipient even if they are not directly reachable. It is particularly useful in situations where the recipient may not have a permanent address or is temporarily residing at a different location.

How “Care Of (C/O)” Works

Using “C/O” in an address signifies that the mail should be delivered to the person or entity specified after the “C/O”, who should then forward it to the intended recipient. For example, if John Smith is staying with Alex Brown, the address would read:

John Smith
c/o Alex Brown
123 Main St
City, State ZIP Code
