This invention relates to methods and apparatus for marking letter mail or mail pieces to provide a fast and convenient way of determining zip code breaks in a stack of letter mail. The mail pieces have marks printed on the edges thereof indicative of the continuity of the same zip codes thereon. The marks are visible when the mail pieces are stacked. Adjacent envelopes with the same zip codes will have an edge mark at the same location, but upon the zip code changing, the next envelope will have a mark placed at a different location. Numbers in sequence can be printed on each of the letters so that a mail clerk can inspect the last letter within a zip code group to determine if there is a sufficient number of mail pieces within that zip code set to allow a postal discount. In an alternative embodiment, the markings on the side of the mail pieces are printed in a pattern so as to form numbers when a stack is viewed from the side. In addition to forming numbers, a pattern line can extend between the numbers. This allows a postal clerk to look at a stack of envelopes in a tray and from the side markings not only determine which of these envelopes are in the same zip code set, but also there would be an indication of the last number of the zip code.
