Three words cover most of label placement. USPS's own pages were read live 2026-08-23; the FedEx placement guidance carried here was last read 2026-07-27.
The box under the label: quoted 2026-08-23, Los Angeles, CA 90011 to New York, NY 10001
Placement advice costs nothing, so here is what the ride itself ran on quote day: a 14 × 12 × 6 inch box at 5 lb, five services, one lane.
| Carrier | Service | Price | Days quoted |
|---|---|---|---|
| UPS | Ground Saver | $19.25 | 6 business days |
| UPS | Ground | $19.30 | 4-5 business days |
| USPS | Ground Advantage | $20.84 | 5-6 business days |
| UPS | 3 Day Select | $27.36 | 3-4 business days |
| USPS | Priority Mail | $29.32 | 3-4 business days |
Three ground services inside a narrow band, then a sharp step up for speed. Placement will not make a package cheaper, but bad placement can make it slower, because a barcode that fails to scan drops the box into manual sorting.
Seams and edges are the enemy
A barcode folded over an edge wrinkles, and a wrinkled code misreads. When one face genuinely cannot hold the whole label, FedEx allows a split: position the barcode on one side of the seam and the recipient’s information on the other, per fedex.com. Flat on a single face beats clever every time.
Tape the edges, never the code
Secure all four label edges so nothing lifts in transit, but leave the printed area, and above all the barcode, uncovered. A code a scanner cannot read sends your box on a detour through human hands, and human sorting is where days get lost.
Reused boxes need housekeeping
The USPS packing page, confirmed live 2026-08-23, tells anyone reusing a carton to cover or black out all old logos, barcodes, shipping labels and addresses before it goes out again. One stray code from the box’s previous trip can win the scanner race and route your parcel into history.
Placement questions
Can I put clear tape over the shipping barcode?
No. FedEx advises against taping over the label or covering it up. Fix the label by its edges and leave the barcode area bare so scanners catch it on the first pass.
Does the label have to go on top of the box?
The published rules ask for flat placement on a single face, parallel to the longest side, rather than a particular face. Pick the largest unobstructed side and stay clear of seams and corners.
What if my box is too small for a flat label?
Use the biggest face available, and if the label still cannot sit flat, split it across the seam the way FedEx describes: barcode wholly on one side, address block on the other. Never wrap the barcode around an edge.
Do old barcodes on a reused box cause problems?
Yes. usps.com asks that when a box is reused, all old logos, barcodes, shipping labels and addresses be covered or blacked out, confirmed 2026-08-23, because sorting equipment scans whichever barcode it finds first.
