How to Address an Envelope

Quick Scoop

Basic Layout (U.S. style)

Think of the front of the envelope as three zones.

  • Top left: Your return address
  • Center: The recipient’s address
  • Top right: Postage stamp

You generally want everything on the same flat side of the envelope.

If the mail can’t be delivered, the return address is how it finds its way back to you.

Step 1: Write your return address

This goes in the top left corner.

Line-by-line format:

  • Line 1: Your full name
  • Line 2: Business or organization (if applicable)
  • Line 3: Street address or P.O. Box, plus apartment/unit if needed
  • Line 4: City, state, ZIP code

Example:

Alex Rivera
1855 Maple Street
Los Angeles, CA 90026 Tips:

  • Write neatly in dark ink.
  • Keep it about 0.25 inch from the top edge and left edge, not too close to borders.

Step 2: Write the recipient’s address

Place this in the center , slightly left of center, leaving at least about a ½ inch margin on all sides.

Standard line order:

  1. Full name (add Mr., Ms., Dr., etc. if formal)
  2. Street address with apartment/suite (same line if it fits)
  3. City, state, ZIP code (ZIP+4 is optional but helpful)

Example (personal mail):

Taylor Robinson
1020 Pine Avenue Apt 3B
Brooklyn, NY 11211 Example (family):

The Smith Family
100 Main St.
New York, NY 12345 Example (business):

Ms. Rachel Kim
ABC Marketing Solutions
500 Market Street Ste 201
San Francisco, CA 94105 Key details:

  • Write the address parallel to the long edge of the envelope.
  • Use clear, plain print (avoid fancy cursive).
  • Many guides recommend all caps and minimal punctuation for machine readability:
    JANE SMITH
    456 OAK AVE APT 2B
    CHICAGO IL 60614

Step 3: Place the stamp

The stamp goes in the top right corner on the same side as the addresses.

  • Use correct postage for weight, size, and destination.
  • Don’t let writing or stickers overlap the stamp area.

Once that’s done, your envelope is ready to mail.

Special situations (quick notes)

  • Apartment or suite: Add “Apt 3B”, “Unit 5”, or “Ste 201” after the street address on the same line if possible.
  • P.O. Box: Replace the street line with “PO Box 123”.
  • To a company (no person): Put the company name on the first line, then the address as usual.
  • To someone at a company: Person’s name (and title if formal) on the first line, company name on the second line.

Example:

Dr. Jordan Ellis
Greenview Medical Group
2500 Oak Street Ste 400
Denver, CO 80202

Mini “story” example

Imagine you’re mailing a birthday card to your cousin in an apartment building. You write your own address in the top left, neatly printed, then center hers on the envelope: full name on the first line, street name plus “Apt 12C” on the second line, city, state, and ZIP on the third. You check that everything is legible, put a standard stamp in the top right, and drop it in the mailbox—no extra fuss, but it looks professional and gets there without confusion.

Quick FAQ style notes

  • “Do I need a return address?”
    It’s technically optional, but strongly recommended so undeliverable mail comes back to you.
  • “Can I put the return address on the back?”
    Some postal workers dislike this; many guides recommend keeping it in the top left on the front.
  • “Does punctuation matter?”
    USPS-focused guides often suggest omitting commas and periods in the recipient address to help automated scanners, though your mail will usually arrive either way.

TL;DR:
Front side only: your info top left, their info centered, stamp top right, all printed clearly in a simple three-line format for both sender and recipient.
