How to Address an Envelope

So let’s be honest—how to address an envelope sounds easy… until you’re standing with a pen in your hand and guessing everything. “Does the stamp go on the top left or right?” “Wait, is this the sender’s address or the receiver’s place?” If you’ve ever stood like that, looking at the empty envelope like you’re trying to solve a math question, trust me—you’re not alone. I’ve gone through the same confusion too.

That’s exactly why I made this guide. I’ve sent both formal and friendly letters, so I’ll show you every step, with no stress. From stamp placement to return address—we’ve got you covered with a simple, visual, and even fun guide.

Even if you’re interested in envelope writing jobs, there are opportunities for you to make a career out of beautifully addressing letters.

Step 1: Choose the Right Envelope Orientation

Step 2: Write the Return Address (Sender’s Info) Top Left Corner

It is an important part of learning how to write return address on envelope correctly, as it helps the postal service send it back to you.

1. If you’re in an apartment, here’s how to write an apartment address on an envelope: add the unit or apartment number after the street.
   Example: 123 Main Street, Apt 4B
2. If you’re using a suite or office, write it like this:
   Example: 456 Elm Road, Suite 201
3. City, State ZIP Code
   Example: Los Angeles, CA 90001

Why it matters:
Think of the return address on envelope as a safety net. If something goes wrong — like the address is incorrect or the recipient has moved — your letter won’t be lost. It will come back to you. Including a return address on envelope is a key part of learning how to write an address on an envelope properly.

Tip:
Write clearly and use capital letters if you can. This helps avoid delivery mistakes.

It’s a small detail, but it can save you time, reduce stress, and even prevent wasted postage. It also shows that you’re careful and professional.

You can also get a return address stamp for faster and cleaner addressing.

Step 3: Write the Recipient’s Address Centre of the Envelope

Wondering how to fill out an envelope? Just follow this format and you’ll be good to go.

Where it goes:
Write the recipient’s address in the center of the envelope, just a little below the halfway point. This helps postal machines and workers read and sort your mail easily, without confusion.

1. If they live in an apartment, include the apartment number.
   Example: 789 Oak Street, Apt 12C
2. If it’s a business address with a suite number, write it like this:
   Example: 101 Pine Avenue, Suite 305
3. City, State ZIP Code
   Example: Houston, TX 77002

For special cases:
If you’re sending mail to someone at a business or another person’s address, use “C/O” (Care Of) before the name.
Example: C/O John Smith

If you’re sending business mail, you can also use “Attn” (Attention) to make sure it goes to the right person or department. For more information please read proper guide Attn on envelope.
Example: Attn: HR Department

Step 4: Place the Stamp Top Right Corner

Don’t let the stamp cover any part of the address.
