Do You Actually Need to Write 'From' and 'To' on an Envelope?
By Chloe Bennett
Addressing errors sideline thousands of letters each sorting shift. Understanding these failure points protects important documents from delivery loops.
The most frequent blunder involves crowding the lower edge. Postal sorting machinery imprints an Intelligent Mail barcode across the bottom 5/8 inch of every envelope. When senders write recipient addresses too low, text collides with this barcode zone. The machine’s camera struggles to resolve the destination text against the sprayed black lines, forcing the envelope into re-sort cycles.
Another regular issue involves misplaced return addresses. Writing a return address across the bottom flap or on the right side of the envelope can trick sorting sensors into treating your address as the delivery target. The letter then gets routed straight back to your mailbox the following morning.
Ink choice also dictates machine readability. Low-contrast pastel markers, gel pens with glitter, and faint pencil strokes fail optical contrast checks. Senders should stick to permanent black or dark blue ink, ensuring stark contrast against white, cream, or light pastel paper.
