📋 Why Return Address Matters for Certified Mail
- • Required for returns: If undeliverable, mail comes back to you
- • Tracking records: Links the mailing to your address
- • Legal proof: Shows you as the sender in disputes
- • Return receipt delivery: Green card returns to your address
Certified Mail Label Placement
The certified mail label (PS Form 3800) must be properly attached to the envelope:
📍 Where to Place the Label
- • Above the recipient address: Most common placement
- • Upper right area: Below postage, but above address
- • Don't cover: Never cover the recipient address or return address
- • Barcode visible: The barcode portion must be readable
✅ Label Do's
- • Peel and stick firmly—press all edges
- • Make sure barcode is flat and readable
- • Fill in recipient address on the label receipt portion

❌ Label Don'ts
- • Don't tape over the barcode
- • Don't fold or crease the label
- • Don't place on envelope seams
- • Don't cover the recipient's address
Return Receipt Attachment
If you're using Return Receipt service (recommended), here's how to attach it:
📬 Physical Return Receipt (PS Form 3811)
- Fill in recipient's name and address on the green card

- Attach to the back of the envelope
📱 Electronic Return Receipt

Frequently Asked Questions
How do I address a certified mail envelope?
Address certified mail the same as regular mail: recipient name, street address, city, state, and ZIP code centered on the envelope. Place your return address in the upper left corner. The certified mail label goes above the recipient address or in the upper right area below the postage.
Where do I put the certified mail label?
Place the certified mail label (PS Form 3800) either above the recipient's address or in the upper right area of the envelope, below where the postage goes. Make sure not to cover the recipient's address or your return address with the label.
Do I need to write "CERTIFIED MAIL" on the envelope?
No, you don't need to write "CERTIFIED MAIL" on the envelope. The certified mail label (green form) identifies it as certified mail. Just address the envelope normally with recipient and return addresses.
Can I print address labels instead of handwriting?
Yes, printed address labels are acceptable and often preferred for clarity. Whether typed or handwritten, the address must be legible. Printed labels reduce errors and look more professional. Just make sure labels are firmly attached.
Where does the return receipt go?
If using a physical return receipt (PS Form 3811 - the green card), it attaches to the back of the envelope. Fill out the recipient's address on the green card, peel off the backing, and stick it firmly to the back. Electronic return receipt doesn't require physical attachment.
Do I need to include apartment numbers?
Yes, always include apartment, suite, or unit numbers when applicable. Put it on the same line as the street address (e.g., "123 MAIN ST APT 4") or on a separate line directly below. Missing apartment numbers can cause delivery failures or delays. See our apartment addressing guide.
Can I drop certified mail in a mailbox, or do I have to go to the post office?
You can drop certified mail in a blue collection box or give it to your mail carrier, but you won't get a dated receipt proving the mailing date. For legal proof of mailing with a postmark, take it to the post office counter where a clerk will scan and stamp your receipt.
