A stamp goes on the front of the envelope in the upper right-hand corner, on the same side as the address.

Basic placement

  • Put the stamp on the front (the side with the recipient’s address).
  • Place it in the top right corner, leaving a small margin from the top and right edges.
  • Make sure it does not cover any part of the address or return address.

Why that spot matters

  • Postal machines are set up to “look” for postage in the upper right corner to scan and cancel it quickly.
  • Some postal regulations (like the US) even say postage must be on the address side in the upper-right area, or it may cause delays or need manual handling.

Little extra tips

  • If you need multiple stamps, line them up neatly together in that same upper-right area without overlapping.
  • Press the stamp down firmly so it adheres well and doesn’t peel off in transit.
