You’ve probably seen “c/o” on an envelope, a delivery label, or even an official document—and paused for a second.
What does c/o actually mean?
Why is it used instead of a full sentence?
And when is it correct—or incorrect—to use it?
People search for c/o meaning because the term looks simple, but its real-life use can feel confusing, especially in formal or professional situations. This article clears that confusion completely, using real examples, everyday language, and practical guidance you can actually use.
C/O Meaning – Quick Definition
C/O stands for “care of.”
It is used when sending mail or packages to someone through another person or organization.
Simple explanation:
- The mail is for one person
- But it is sent to another person’s address
Short examples:
- “Ali Khan c/o Sara Ahmed”
- “John Smith c/o ABC Company”
- “Package delivered c/o front desk”
“Care of” tells the delivery service who should receive the item and who will pass it on.
Origin & Background of C/O
The term “care of” dates back several centuries, long before emails and digital addresses.
Historical roots:
- Originated in postal systems in the 18th century
- Used when people did not have permanent addresses
- Common among travelers, merchants, and diplomats
How it evolved:
- Became a standard postal abbreviation
- Adopted globally across English-speaking countries
- Still used today in:
- Legal documents
- Business correspondence
- International shipping
Despite modern technology, c/o remains relevant because people still:
- Live temporarily somewhere else
- Work through offices
- Receive mail via third parties
Real-Life Conversations (How People Actually Use It)
WhatsApp Chat
Person A:
Hey, should I write your name on the parcel?
Person B:
Yeah, write my name c/o my brother. I’m staying at his place.
Instagram DM
Person A:
The brand asked for your address.
Person B:
Send it c/o my office, I won’t be home this week.
Text Message
Person A:
The documents arrived today.
Person B:
Great, addressed c/o reception, right?
These are everyday situations where c/o quietly solves a delivery problem without needing long explanations.
Emotional & Psychological Meaning
On the surface, c/o looks technical. Emotionally, it represents:
- Trust – You trust someone to receive something important
- Flexibility – You’re not tied to one location
- Connection – Someone else plays a role in helping you receive what matters
In modern life—remote work, shared housing, travel—c/o reflects how people actually live today, not how addresses worked decades ago.
Usage in Different Contexts
1. Social Media & Online Forms
- Used when shipping influencer products
- Helpful for creators without fixed addresses
- Often seen in bio links or brand collabs
2. Friends & Family
- Staying temporarily with relatives
- Students living away from home
- Writing letters or receiving documents
3. Work & Professional Settings
- Employees receiving personal mail at work
- Legal or HR correspondence
- Freelancers using coworking spaces
4. Casual vs Serious Tone
- Casual: “Send it c/o my cousin”
- Formal: “Mr. David Lee c/o Finance Department”
The meaning stays the same, but tone and formatting matter.
Common Misunderstandings About C/O
❌ “It means delivery person”
No. c/o is not the courier.
❌ “It replaces the recipient’s name”
Wrong. You must still name who the item is for.
❌ “It’s outdated”
False. It’s still widely used in:
- Banking
- Immigration
- Legal mail

❌ “You can use it anywhere”
Avoid using c/o when:
- The recipient has a permanent address
- The sender already knows the exact location
