A recipient who is temporarily residing elsewhere or receiving mail at another location can have a letter sent to them at an address marked “in care of.” The correct approach to address a letter is to include the actual recipient’s name under “C/O John Smith,” for instance.
If you’re worried that the postal service won’t deliver your letter because it has an unknown name, use a “in care of” address instead. The recipient’s information is put in the centre of the envelope’s address, while the sender’s name and address are written in the corner on the left.
