C/o (Italy)

In Italy, c/o, also ℅ or in the capital form C/O, is an abbreviation used in postal shipments to indicate a person other than the recipient, but to whom the message is physically addressed. It is synonymous with "at".^[1]

The abbreviation originates from the English expression care of (which literally means "in the care of")^[1] understood as "domiciled at" and originally had the purpose of allowing the delivery of mail to people staying with others and therefore without their own address or not present at their own address. The relative character is encoded in Unicode as U+2105.
