Screenshots die, emails survive
Keep the original message rather than a photo of the screen. Kiosks read a crisp code and give up on a compressed screenshot of a screenshot.
Counter printing
QR code shipping labels, explained
The QR code sitting in your returns email is not postage and never was. It is a claim ticket: scanning it at the right counter or kiosk pulls up a label that was already bought and paid for, and prints it on paper right there.
All three big carriers now run a version of this, they run it differently, and each accepts the code at a different list of places. Here is what each program actually does, quoted from the carriers' own pages.
Three carrier programsCounter and kiosk routesSources dated 2026-07-28
Paid already, printed later
The money moved when the label was created. The code just moves the paper.
The three programs, and where each code is accepted
- USPS Label Broker. A Label Broker ID is a QR code plus an 8 to 10 character alphanumeric string. A retail associate at a participating Post Office scans it and prints the label free of charge, and self-service kiosks accept either the code or the typed ID (usps.com, checked 2026-07-27). When no participating branch is close, the same program will post you the printed label for $1.65 per label, which is the slow fallback rather than the default.
- FedEx. Two distinct paths. Returns customers can present a company-issued QR code at a FedEx Office or a participating Walgreens for printing, and the Walgreens page states plainly that the store “can print your FedEx shipping or returns label by scanning your QR code when you drop off your package”. Separately, a barcode generated in the FedEx mobile app can be taken to a FedEx Office or participating FedEx Ship Center to be scanned and printed (fedex.com, checked 2026-07-28).
- UPS. The returns guidance lists “Scan and print by mobile barcode at a UPS location” as one of the ways to hand a package back (ups.com, checked 2026-07-28). The page does not break down which of the four UPS channels offer it, so treat a staffed counter as the safe assumption and a street drop box as a definite no.
The common thread is that a code only exists because somebody bought a label. If you are the one shipping and nobody has bought anything yet, no QR code is going to appear, and the counter will sell you postage the ordinary way instead.
What sits behind the code: a real label, priced
Printing method has no effect on postage. To make that concrete, here is a small padded envelope holding a phone, quoted through the SMKlog calculator on 2026-07-28 from Newark, NJ 07102 to Atlanta, GA 30303. Whether that label ends up on thermal stock, on office paper or on a Post Office printer, the money below is the same.
| Carrier | Service | Price | Window returned |
|---|---|---|---|
| USPS | Ground Advantage | $8.86 | 8-9 business days |
| FedEx | Ground Economy | $10.06 | 6-7 business days |
| UPS | Ground | $10.31 | 2-3 business days |
| UPS | 3 Day Select | $15.13 | 5-6 business days |
| UPS | 2nd Day Air | $15.38 | 2-3 business days |
The delivery windows are printed exactly as the carriers returned them that day, oddities included: the cheapest row quoted the longest window, and the two UPS tiers costing five dollars more than Ground promised nothing faster than Ground did. That is a good argument for reading the window on the checkout screen rather than assuming the pricier row is quicker.
How our labels fit into this
We do not mint carrier QR codes ourselves, but a domestic USPS label bought here comes with the Postal Service's own one: since 2026-09-05 the label page carries a USPS Label Broker QR code next to the 4 by 6 PDF. Show the code at a participating Post Office counter or kiosk and they print the label; or print the PDF at home, forward it to a friend or an office, or open it on a phone at any print counter that takes email. Use either the code or a printed copy, not both. UPS and FedEx labels, and USPS labels going abroad, are print-at-home only. The printer-free comparison lives on our no-printer guide, and the Postal Service program behind most return emails is unpacked on our Label Broker page.
If you are the one arranging a return for someone who has no printer, a Label Broker ID from a USPS-integrated platform is still the cleanest hand-off available, and it beats emailing a PDF to a stranger and hoping. We sell domestic parcel labels and international ones to Canada, the UK, Germany and Australia; other cross-border requests, or any request to store and pick goods for you, are outside our scope entirely.
Seal the box first
Counters print labels; they do not pack for free. Arrive with a taped carton and the whole errand takes two minutes.
Check the branch, not the brand
Participation varies location by location in every one of these programs. One quick look at the carrier finder saves a wasted trip.
QR label questions
What is a QR code shipping label?
It is a short code that stands in for a label somebody already paid for. Nothing on your phone is postage; the code tells a counter or a kiosk which label to fetch and print, and the paper that comes out is the actual shipping label.
Can the Post Office print a label from a QR code?
Yes. USPS Label Broker lets a retail associate scan the QR code at a participating Post Office, and self-service kiosks take the same code or an 8 to 10 character Label Broker ID typed in, at no charge, per usps.com checked 2026-07-27. If no participating branch is near you, USPS will mail the printed label instead for $1.65 per label.
Can UPS or FedEx print my label for me?
Both offer a version of it. FedEx says Walgreens can print a FedEx shipping or returns label by scanning your QR code, and that a barcode generated in the FedEx mobile app can be printed at a FedEx Office or participating FedEx Ship Center, per fedex.com checked 2026-07-28. UPS tells returners they can scan and print by mobile barcode at a UPS location, per ups.com checked 2026-07-28.
Does SMKlog issue QR codes for its labels?
For domestic USPS labels, yes: a label bought here comes with a USPS Label Broker QR code on its label page, next to the printable 4 by 6 PDF, since 2026-09-05. Any participating Post Office counter or self-service kiosk scans it and prints the label at no charge; use either the code or a printed copy, not both. UPS and FedEx labels, and USPS labels going abroad, stay print-at-home — the UPS and FedEx QR routes above belong to those carriers and to the retailers who set up your return.
