Print there, buy elsewhere
The kiosk will happily print a label you already own from a Label Broker code, at no charge. That is the combination worth using: online pricing with lobby hours and lobby scales.

USPS self-service kiosk: what it can and cannot do
A kiosk weighs parcels, sells postage, prints labels and takes a Label Broker code around the clock in a Post Office lobby. What it cannot do is sell you the commercial price list, which is where the money on an ordinary parcel actually sits.

Great printer, expensive shop
Buy the label online, print it on the machine. The kiosk earns its keep on hours, not on price.
What the machine in the lobby can do
A self-service kiosk is a small Post Office counter with no queue and no closing time. USPS lists what it handles, and the list is longer than most people assume.
- USPS says a kiosk can buy stamps, weigh packages, print and pay for shipping labels, scan a prepaid label, mail letters or packages, look up a ZIP Code, renew and pay PO Box renewal fees, and print a Label Broker label (per faq.usps.com, checked 2026-07-28).
- The hours are the real selling point. The Postal Service describes kiosk customers as able to purchase stamps and weigh and mail cards and packages 24 hours a day, seven days a week (per about.usps.com, checked 2026-07-28).
- It will print a label you already bought, if that label came with a Label Broker code. USPS says a Label Broker ID, which is a QR code, can be taken to a Post Office location that has Label Broker at the counter or to a Label Broker self-service kiosk and printed at no charge (per usps.com, checked 2026-07-28). Having USPS post the printed label to you instead carries a $1.65 fee per label.
What it cannot do is give you a better price than the counter it stands next to. A kiosk sells retail postage, and retail postage is a different price list from the one an online label is bought on.
The price list a kiosk is working from
USPS publishes two columns for the same parcel. Retail is what you pay standing in a Post Office, including at a lobby machine. Commercial is the tier an online label is priced on.
| Weight | Retail price | Commercial price | Difference |
|---|---|---|---|
| 1 lb | $10.60 | $8.15 | $2.45 |
| 5 lb | $15.80 | $11.02 | $4.78 |
| 10 lb | $19.40 | $14.44 | $4.96 |
| 20 lb | $27.30 | $19.66 | $7.64 |
Same parcel, same zone, same truck. The only variable is how the postage was bought. That gap is the reason a lobby kiosk is a brilliant place to print a label and an expensive place to buy one.
The same comparison on a live lane
The published tables are one view. Here is the other: five boxes quoted on a real route, with the retail figure the carrier returned alongside each rate.
| Packed box | Weight | Price you pay | Retail figure returned |
|---|---|---|---|
| 10 x 8 x 4 in | 1 lb | $9.91 | $10.95 |
| 12 x 10 x 6 in | 4 lb | $8.48 | $16.40 |
| 12 x 10 x 6 in | 5 lb | $14.02 | $18.40 |
| 14 x 12 x 8 in | 8 lb | $15.73 | $20.40 |
| 16 x 14 x 10 in | 16 lb | $22.62 | $31.45 |
The 4 lb row is the one to look at: $8.48 against a $16.40 retail figure on the same box, same day, same route. Our price is the entire amount collected at checkout with SMKlog inside it, not postage alone. The sensible pattern falls out of the table by itself: buy online, then use the kiosk for what it is genuinely good at, which is printing and weighing at eleven at night.
The routine worth adopting reads like this. Price the parcel here, pay as a guest, print at home or carry the code to the lobby machine, then hand the box over at the counter, at the chute or at your own door.
Midnight is the real feature
A machine that weighs and mails at three in the morning solves a problem no counter can. For anyone shipping around a day job, that alone is worth knowing about.
Retail is a different list
The counter price and the online price are two published tiers, not a discount someone chose to give you. Notice 123 prints both columns side by side for anyone who wants to check.
Kiosk questions
What can a USPS self-service kiosk do?
USPS lists buying stamps, weighing packages, printing and paying for shipping labels, scanning a prepaid label, mailing letters or packages, looking up a ZIP Code, paying PO Box renewal fees and printing a Label Broker label. The machines are described as available 24 hours a day, seven days a week.
Will a kiosk print a label I bought online?
It will if the label came with a Label Broker code. USPS says a Label Broker ID, which is a QR code, can be taken to a Post Office with Label Broker at the counter or to a Label Broker self-service kiosk and printed at no charge.
Is a kiosk cheaper than buying a label online?
No. A kiosk sells retail postage. USPS Notice 123 lists Ground Advantage at Zone 4 as $15.80 retail against $11.02 commercial for a 5 lb parcel, prices effective July 12, 2026, and that gap widens with weight.
Can I weigh a package at a kiosk without buying anything?
Weighing is one of the functions USPS lists for the machines, and lobby access runs around the clock. If you only need the weight before pricing a label at home, that is a reasonable use of five minutes.
