Where do you put the stamp and address on an envelope?

How to address an envelope
  1. Write the return address in the top left corner.
  2. Then, write the recipient’s address slightly centered on the bottom half of the envelope.
  3. To finish, place the stamp in the top right corner.

Does it matter where the stamp goes?

Placement of Stamp

The return address should be in the top left corner, the mailing address should be written clearly in the center, and the stamp should be fitted securely to the top right corner of the envelope. Stamps should not overlap, and extra postage can be placed on the back of the envelope.
