You’re busy, so let’s get straight to the point: addressing an envelope correctly matters. Whether you’re mailing letters, invitations, or holiday cards, taking the time to format the recipient’s name, honorifics, and your return address correctly ensures smooth delivery and sends a message of care and attention—especially in an era of digital shortcuts.

Understanding Envelope Addressing

Proper envelope addressing is key to making sure your mail reaches the right person. A clearly written envelope helps the postal service work efficiently and leaves a positive impression on your recipient.

Why Proper Addressing Matters

A well-addressed envelope:

  • Ensures accurate delivery.
  • Allows postal workers to process mail efficiently.
  • Reflects professionalism and courtesy.
  • Reduces the risk of mail being delayed, lost, or returned.

How to Address an Envelope in 3 Easy Steps

To get started, you need three pieces of information:

  1. The recipient’s full address
  2. Your return address
  3. A postage stamp

Write or type all “To” information in the center of the front side of the envelope using the format below.

Step 1: The “To” Section (Recipient)

Write the recipient’s address in four clearly printed lines:

Line 1: Recipient’s Name

Write the name in block capital letters for legibility. Avoid cursive or fancy handwriting—postal workers aren’t psychic.

Example:
BULL GARLINGTON

Tip: If you’re writing to a family, include the parents’ names for clarity.

Line 2: Company Name (Optional)

Only include this if you’re sending to a business address. There’s no need for “c/o” unless the person is genuinely in someone else’s care.

Example:
ANALOG ATTORNEY

Line 3: Street Address

Use the format: Street Number + Street Name. If there’s an apartment, suite, or office number, include it after the street name—or on a separate line if it’s too long.

Example:
P.O. BOX 352

Line 4: City, State, ZIP Code

Write the city name, then the two-letter postal abbreviation for the state in uppercase (no commas), followed by the ZIP code.

Example:
LAKE ZURICH IL 60047

Step 2: The “From” Section (Return Address)

Your return address goes in the top left corner of the envelope and should mirror the format used for the recipient’s address. It must be legible and complete, including apartment numbers and ZIP codes. Avoid placing it on the back of the envelope—postal workers don’t like flipping mail over.

Example:

YOUR NAME  
111 YOUR STREET AVENUE  
YOUR CITY ST 77744

This return address allows your letter to come back to you if undeliverable.

Step 3: The Stamp (Postage)

Affix a postage stamp in the top right corner of the envelope. This helps the post office quickly identify and process your mail. Ensure the stamp is securely attached and doesn’t cover any part of the address.

You can purchase stamps at:

  • USPS.com
  • Stamp machines in post offices
  • Directly from post office clerks

Special Address Formats

Some situations require a bit more care when addressing envelopes—especially for military or international mail. Here’s what you need to know:

Mailing to a U.S. Military Address

Military mail requires a specific format. Use APO (Army or Air Force Post Office) or FPO (Fleet Post Office for Navy, Marine Corps, Coast Guard). Instead of a city and state, you’ll use special military codes:

  • AA – Americas
  • AE – Europe
  • AP – Pacific

Example:

LT DAVID HAYNES  
HEADQUARTERS COMPANY  
7TH ARMY TRAINING CENTER  
ATTN: AETT-AG  
UNIT 28130  
APO AE 09114-8130

Mailing Internationally

International addresses use the same basic format with a few tweaks:

  • Replace “State” with the Province or Region.
  • Use the local postal code format.
  • Always write the country name in capital letters on the last line.

Example (Canada):

DR. BIG FOOT  
111 SASQUATCH DRIVE  
MOOSE JAW SK  S6H 2X1  
CANADA

By following these guidelines, your envelope won’t just look neat and professional—it will also get where it needs to go without delay. Good addressing is a small effort that makes a big difference.
