How to Use “Care Of” (C/O) in an Address
When sending mail to someone at a business, temporary residence, or another person’s home, using “care of” (C/O) ensures your mail reaches the right recipient.
This guide explains when to use C/O, how to format it correctly, and includes real-world examples.
What Does “Care Of” Mean?
“Care of” (written as C/O) tells the postal service that the recipient is receiving mail at someone else’s address. It helps route the mail through a third party who can deliver it to the intended person.
- Used when someone doesn’t receive mail at their primary address
- Common for business contacts, guests, or temporary stays
- Ensures delivery through a trusted intermediary
When Should You Use C/O?
Use “care of” in situations like:
- Sending mail to someone at their workplace
- Mailing a guest staying at someone else’s home
- Contacting someone through a business or organization
- Reaching someone without a permanent mailing address
How to Write an Address with C/O
Follow this standard format:
Recipient Name
C/O Person or Business Name
Street Address
City, State ZIP Code
Example:
Jane Smith
C/O John Doe
123 Main Street
Dallas, TX 75201
Best Practices for Using C/O
- Always list the recipient’s name first
- Write “C/O” before the intermediary’s name
- Double-check spelling and address details
- Use clear formatting to avoid delivery delays
Common Mistakes to Avoid
- Putting the C/O name before the recipient
- Forgetting to include “C/O” entirely
- Using unclear or incomplete addresses
- Mixing business and personal names incorrectly
Why Proper Addressing Matters
Correct formatting helps ensure your mail is delivered quickly and accurately. Using “care of” properly reduces confusion and prevents returned mail.
