When addressing a letter or holiday or birthday cards, you traditionally write the person’s name and address, and your return address. But before you mail out your letter, you may want to ask yourself if what you’re sending needs a C/O, which stands for “in care of.” This ensures that your letter, card or package gets delivered to a specific person. Here are a few instances in which C/O may come in handy:
1. Sending tax documents
If you need to send an important tax document or piece of information to your accountant or attorney, make sure to send it “in care of” to ensure that it gets to the right person.
2. Trying to get in touch with someone
Are you trying to get in touch with an old friend or track down a past co-worker? If so, you should address the envelope with C/O. This will ensure that even if you’re sending the letter or card to the wrong address, it will end up in the hands of the proper recipient. For instance, if you don’t know the recipient’s home address, you can use “in care of” and send it to their office or place of work. In this case, you would write their name at the top, followed by c/o “place of business.” Below that, you will write out the address of the office.
