What can I do at a USPS self-service kiosk?

A USPS self-service kiosk handles the most common post office transactions without a clerk: weighing packages and letters, printing postage labels, buying stamps, and looking up ZIP codes. Many sit in post office lobbies that stay open 24 hours, so you can mail a package at midnight on a Sunday when the counter closed hours ago.

TaskKiosk can do it?
Weigh a package and print postageYes, including Priority Mail and other services
Buy stamps and stamped envelopesYes, books of stamps and individual stamps
Look up a ZIP codeYes, built into the touchscreen
Ship an international packageYes, with customs forms printed at the kiosk
Pay with cashNo; kiosks accept debit and credit cards only
Buy a money orderNo; that needs the retail counter

When is the kiosk better than the counter?

The kiosk wins on two things: speed and hours. If you have a ready-to-mail package, the kiosk weighs it, sells you the postage, and prints the label in about a minute, with no line. And because the lobby stays open around the clock at many locations, you can drop off a package that makes the next day's pickup instead of waiting for the counter to open. For anything complex, like a passport application, a pickup hold, or a package that needs special handling, the counter still wins.

What should you know before you go?

The kiosk takes cards only, so bring a debit or credit card: no cash, no checks. The built-in scale has weight limits, so oversized freight stays a counter job. After the kiosk prints your postage, you still need to put the package in the right bin or chute; the kiosk prints the label but does not sort your package for you. And the kiosk cannot sell certified mail with a physical return receipt card at the machine, though it does sell certified postage.

Do the kiosks have a history?

They do. The machines started rolling out in the early 2000s under the name Automated Postal Center, or APC, and the USPS later rebranded them as self-service kiosks. Early versions were notorious for long lines of their own when only one machine served a busy office. Today they are standard fixtures in larger post offices, and their software handles international customs declarations, which used to require a counter visit and paper forms.

Is there a Canadian equivalent?

Canada Post does not run the same 24-hour kiosk network, but its online tools cover similar ground. Snap Ship, Canada Post's online postage tool, lets small senders print shipping labels at home, which is the kiosk's closest cousin north of the border. Many Canadian postal outlets inside pharmacies and stores also keep long evening hours, so the "mail it after dinner" convenience exists in a different form.
