How to Write an Address on an Envelope

Address basics  |  April 4, 2026  |  2 min read

Most mail is sorted by machines that scan an envelope in a fraction of a second. Putting each part in the expected spot helps your letter arrive on time.

The three zones

• Return address: top left corner.
• Postage stamp: top right corner.
• Delivery address: centered, slightly below the middle of the envelope.

Writing the delivery address

• Recipient name on the first line.
• Street address with any unit on the second line.
• City, state and ZIP code on the last line.

Keep lines left aligned with each other, even though the block itself sits near the center.

Keep the bottom clear

Machines print a barcode along the bottom edge. Leave roughly the lower 5/8 inch empty so the barcode can be applied cleanly.

Handwriting tips

Use dark ink on a light envelope. Print clearly in capital letters, avoid cursive and do not underline the ZIP code.

Printing labels

If you print labels, use a clear sans-serif or typewriter font at 10 to 12 points. Test your label template with long names and addresses that include units, which is exactly where generated addresses help.
