Once upon a time (30+ years ago) an employee of the USPS told me that I could tape a stamp on the envelope as long as it was done along the edges so that it could be properly cancelled. Yesterday that was contradicted by the lady at the window. She said no tape… use glue.
Over the years I’ve taped stamps without any problems…usually just first-class letters.
I once taped a stamp on a package and it came back as already having been cancelled. I wonder if that was the accurate reason for the rejection or whether they didn’t have a “there’s tape on this stamp” rejection notice available. I wasn’t surprised that the stamp had already been used and I thought that they might have used an ink that only machines could read.
Finally, however which way I secure postage to a package (not a letter), if I get the lady at the window to accept it can I be assured that nobody else is going to reject it later?
