Care Of Symbol

The symbol is read aloud as "care of," abbreviated from the phrase. It is used in postal addressing to indicate that a piece of mail should be delivered to someone at an address where they are not the primary recipient, typically through an intermediary such as a business, organization, or another person. The character is a single typographic ligature of the letter "c" and a forward slash, standing in for the longer written abbreviation "c/o."

Primarily found on envelopes and parcels, it appears on a line before the recipient's name when the address belongs to a third party. It also appears in other contexts where a temporary or indirect delivery arrangement is noted, such as event registration forms, correspondence logs, or database address fields. The symbol belongs to the Letterlike Symbols block and is considered a standard typographic character rather than an emoji.
