Question: Where to Put Stamp on Letter

The stamp or postage is placed in the upper right-hand corner of the envelope.

Can I put a stamp anywhere on an envelope?

Yes you can actually put the stamp anywhere on the front of the letter and it will still work. The top right corner is the traditional place to put it and is easier for the postmaster / or machine / to do it in the same place on each one and just help speed up the process.

Does the stamp have to be in the right corner?

Stamps must be affixed firmly in the upper right corner of the address side of the mail cover. Any stamp partly concealed by an overlapping stamp may not be counted as postage.
