where does a stamp go on an envelope

The stamp goes on the front of the envelope, in the top-right corner of the address side.

Exact placement (quick guide)

• Use the front (the side where you write the recipient’s address), not the flap side.

• Put the stamp in the upper-right corner , with a small margin from the top and right edges.

• If you need multiple stamps, place them side by side in that top-right area without overlapping.

An example layout:

• Top left: your return address.

• Center: recipient’s address.

• Top right: stamp(s).

What if you put it elsewhere?

• Many postal workers will still try to send it if they can find the stamp, but it may be delayed or kicked out of sorting machines.

• Machines are designed to look for postage in the top-right, so that’s the safest place to avoid problems.

TL;DR: Front side, top-right corner of the address side, with your addresses laid out clearly around it.
