Correct placement helps automated mail processing and keeps postage separate from the delivery address and return address.
Standard envelope layout
Place the return address in the upper-left, the delivery address near the center, and postage in the upper-right. Leave clear space around addresses and postage.
Using more than one stamp
Place additional stamps next to the first stamp in a neat horizontal row when space allows. Do not overlap them or cover printed value, design elements used for validation, or cancellations.
Postcards and reply envelopes
Use the marked stamp area in the upper-right of the address side. A self-addressed stamped envelope should already show the return recipient as the delivery address and have adequate postage for its expected contents.
Frequently asked questions
Which corner does the stamp go in?
The upper-right corner of the address side.
Can stamps go on the left?
Use the upper-right to support normal automated processing.
Can stamps overlap?
No. Affix each stamp flat and fully visible.
