Basic Envelope Address Format

Before we look at the basic envelope address format, do you know the cost of getting it wrong?

An incorrectly formatted envelope can cause delivery delays, misdelivery to the wrong recipient, or even have your mail returned to the sender.

Use this structure.

When learning how to write an address on an envelope, the recipient’s address comes first. Use the following structure:

1. Recipient’s Address

Line 1: Recipient’s full name with proper title

Line 2: Street address, including unit/apartment if needed

Line 3: City, state (abbreviation), ZIP code

Line 4: Country (only for international mail, all caps)

Example (Domestic):

Dr. Amanda Lee

456 Oakwood Ave Apt 12B

Denver, CO 80204

Example (International):

Dr. Amanda Lee

456 Oakwood Ave Apt 12B

Denver, CO 80204

UNITED KINGDOM

2. Return Address

The return address ensures undeliverable mail comes back to you. It follows the same structure as the recipient’s address but in a smaller font.

Line 1: Sender’s full name with proper title
Line 2: Street address, including unit/apartment if needed
Line 3: City, state (abbreviation), ZIP code
Line 4: Country (only for international mail, all caps)

Example:

Where to Write on the Envelope

Let’s look at where to place addresses on an envelope for proper mailing.

An envelope has three elements: the recipient’s address, the return address, and the postage stamp. 

Here’s how they should be positioned.

1. Recipient’s Address

The recipient’s address on the envelope goes in the center, slightly lower than the exact middle. It is because postal scanners are designed to read addresses in this area, known as the lower right quadrant.

It goes like this:

• Leave about 1 inch of blank space on all sides.
• Keep the address block around 4 inches wide and 2 inches tall on a standard envelope.
• Leave the bottom 5/8 of an inch completely blank so the postal barcode has space.

2. Return Address

Your return address tells the postal service where to send the mail if delivery fails. It goes in either: 

• The upper left corner
• Or on the front. 

For wedding invitations or formal mail, it’s also acceptable to put it on the back flap.

3. Postage Stamp

Stamps always go in the upper right corner with at least:

• 1/4-inch space from the top edge
• 1/4-inch space from the right edge

Avoid putting any text, designs, or smudges in this zone to keep the stamp area clean.

Adapting for Different Envelope Sizes

Envelope Type	Adjustment Needed
Standard #10 Business	Follow the usual placements — no changes needed.
Legal-Size	Position recipient’s address closer to the center for visual balance.
Small Invitations	Shrink the address block proportionally while maintaining margins.
Large Envelopes/Packages	Use the same layout rules, but leave space for tracking labels or barcodes.
