How to Address an Envelope Correctly: Step-by-Step Format Guide and Best Practices
By Robert Thorne
Every standard commercial or personal envelope contains three operational quadrants. High-speed sorting cameras rely on these zones remaining distinct, free from decorative stickers, tape, or stray markings.
The return address placement sits securely in the upper-left quadrant. Keep this block at least 0.33 inches away from both the top and left outer edges. If delivery fails due to a change of address or an expired forwarding order, postal couriers rely exclusively on this block to return the document to you.
The postage stamp placement occupies the top-right corner. Affix your definitive stamp, meter strip, or printed PC Postage label roughly 0.25 inches from the top and right borders. Positioning the stamp here allows automatic canceling machines to verify payment and apply postmarks in a single mechanical pass.
The recipient mailing address commands the lower-middle portion of the envelope, known to postal workers as the Optical Character Reader (OCR) read area. This zone starts approximately 5/8 inch from the bottom edge and must maintain an open border of at least 0.5 inches on the right and left sides. Leaving the bottom 5/8-inch margin completely blank is vital; that space is reserved for the spray-printed fluorescent barcode applied at sorting hubs.
