The return address goes on the front , in the top left corner of the envelope, above and to the left of the recipient’s address.

Where to put the return address on an envelope

  • Front of envelope, top left corner.
  • Keep it a bit down from the very top and a bit in from the left edge (around 0.25 inch is common, but it doesn’t have to be exact).
  • The recipient’s address belongs in the center area, slightly left-aligned.
  • The stamp or postage goes in the top right corner, not touching the addresses.

Simple layout (front side)

  • Top left:
    Your name
    Your street address or P.O. Box
    City, State ZIP Code
  • Center:
    Recipient name
    Street address / Apt or Suite
    City, State ZIP Code
  • Top right:
    Stamp / postage.

Can it go anywhere else?

Most postal guidelines and mail experts strongly recommend the top left front as the safest, most machine‑friendly spot.

People sometimes use alternatives, especially with decorative envelopes:

  • On the back flap (center or along the top of the flap).
    • This is commonly done for wedding invites or fancy stationery.
    • However, some users report that machines occasionally mistake it for the destination address and misroute or return mail, especially if the front isn’t very clear.
  • Small label at the very top of the back flap, written smaller than the main address, to reduce confusion.

If you care most about reliability (bills, legal docs, important forms), stick with the top left on the front.

Quick numbered how‑to

  1. Place the envelope so the flap is on the back and the long edge is horizontal.
  2. In the top left front , write your:
    • Name
    • Street address or P.O. Box
    • City, State ZIP Code
  1. In the center front , write the recipient’s full address in three lines (name, street, city/state/ZIP).
  1. Put the stamp in the top right corner on the front.

Mini “forum‑style” note

If your envelope has artwork where the return address usually goes, most people suggest using a small label in the top left anyway, or a neatly printed return on the back flap—but know that the top left front is still the most “postal‑friendly” spot.

TL;DR: For the best chance of smooth delivery, put the return address on the front, top left corner of the envelope, with the recipient in the center and the stamp in the top right.
