Why Your Mail Gets Returned: the Critical 'From' and 'To' Address Mistake You Might Be Making
Getting an envelope through processing machinery without a hitch requires treating the envelope face as a grid divided into three dedicated zones:
The top left corner holds the return address. This block alerts the postal system who paid for or originated the item and where to route it if delivery fails. Keep this block at least one-quarter inch away from the top and left physical paper edges, and never let it extend past the midpoint of the envelope.
The center of the envelope belongs entirely to the recipient address. Postal standards mandate that this block sit horizontally centered, anchored roughly within the lower half of the envelope. The machine expects the final line, city, state, and ZIP code, to sit between 5/8 of an inch and 2.75 inches from the bottom edge.
The top right corner is reserved strictly for postage stamp placement, printed meter stamps, or permit imprints. Maintain clear separation between the postage area and the recipient block. If a stamp overlaps the delivery text or crowds the right margin, the scanner's optical window registers an anomaly and sends the letter to a reject stack.
