Bad, Barcode, Bad!

Comments off

The tall and short bars on an envelope represent the destination zip code and are used to help machines sort the mail. But what would happen if the barcode was wrong?

This envelope has the wrong POSTNET barcode. It was sent from Baltimore to Atlanta, but we coded it for Hilo, Hawaii.

As expected, the envelope went to Hawaii. Postal employees marked out the barcode (and the orange code on the back) and just dropped it back into the mail. This envelope took two weeks longer than a properly addressed envelope mailed at the same time. So, if you want to mail something but not have it delivered promptly, this is one way to do it.

The most interesting thing is that it has a second postmark from Hawaii, which proves that it actually made the journey as opposed to just being delayed somewhere on the mainland.
