USPS Label Broker, explained without the mystery

That QR code in your inbox with instructions to visit a Post Office is a Label Broker ID. It means someone bought USPS postage for your package and left the printing to the Postal Service. Here's what the code is, where it turns into a real label, and what this program does and doesn't cover.

The postage is already paid. The QR code just tells the Post Office which label to print for you.

What the program actually is

Label Broker is the Postal Service's answer for people who need to print a shipping label but don't have a printer. A Label Broker ID, which is a QR code plus an 8-10 character alphanumeric code, gets scanned at a participating Post Office counter or self-service kiosk, and the label prints there at no charge. All of this is per usps.com, checked 2026-07-27.

Using an ID you were sent

  1. Keep the message. The ID arrives by email or text, typically from a retailer or marketplace handling your return, and sometimes from USPS Click-N-Ship.
  2. Pack the item completely. The Post Office prints the label but expects a ready-to-ship package; sealing and padding are on you.
  3. Find a participating location. Not every branch offers it, so run the USPS location finder before walking over. Counters and kiosks are listed separately.
  4. Show the code, hand over the box. The clerk or kiosk scans the ID, the label prints, and the package is accepted then and there.

The economics are simple to state plainly: printing through Label Broker costs nothing extra because the postage behind the QR code was purchased when the label was created. The program moves the paper, not the payment.

Whose tool this is

Label Broker belongs to USPS, full stop. We're describing it because our readers meet these QR codes constantly through marketplace returns, not because SMKlog operates any part of it. When something on this page conflicts with usps.com, trust usps.com.

Where SMKlog fits

Labels bought through our calculator open in a print view that works from any phone browser, so the usual path is printing at home rather than at a counter. The QR-code errand simply isn't required for a label you can print yourself.

For sellers reading this

If your buyer or return recipient has no printer, a Label Broker ID from a USPS-integrated platform is the cleanest hand-off, and it beats emailing PDFs to strangers. For your own outbound shipping, a home-printed label stays the faster route.

Label Broker questions

What is a USPS Label Broker ID?

It's a QR code paired with an 8-10 character alphanumeric code that stands in for a shipping label you haven't printed yet. Per usps.com, checked 2026-07-27, retailers and ecommerce platforms send it by email or text, and Click-N-Ship can produce one as well.

Where does the Label Broker QR code get printed?

At Post Office locations that support Label Broker at the counter and at self-service kiosks in select locations, per usps.com as of 2026-07-27. USPS's location finder shows which sites participate, and the printing itself carries no charge.

What do I bring to the Post Office for Label Broker?

Two things, per the USPS page: your ready-to-ship package, sealed and packed, and the Label Broker ID on your phone or on paper. Staff or the kiosk print the label and the package enters the mail stream on the spot.

Is Label Broker part of SMKlog?

No, and this page won't pretend it is. Label Broker is USPS's own program for its own labels. SMKlog labels arrive as a file with a built-in print view that works from a phone or computer, so most buyers here never need the QR path at all.
