How to Buy Stamps from USPS: Online, In Person, and What to Expect

You can buy stamps from USPS in two main ways: order them online through the USPS Postal Store on usps.com, or buy them in person at a Post Office or an approved retail location. Online ordering is the better fit if you want specific stamp designs, collectible sheets, or bulk rolls and don't mind waiting for delivery; buying in person is faster if you need stamps today and only require common denominations. USPS.com lists "Buy Stamps" and "Stamps & Supplies" among its quick tools and Send menu, and it also runs a dedicated "USPS Stamps" section under featured products.

Buying stamps online through the USPS Postal Store

USPS.com's Shop section includes a Postal Store with categories for Stamps, Shipping Supplies, Cards & Envelopes, Personalized Stamped Envelopes, Collectors, Gifts, and Business Supplies. The site also provides a search box labeled "Search the Postal Store: Keyword or SKU," which is the most direct way to find a specific stamp issue or product code.

A practical sequence looks like this:

1. Go to usps.com and open the Shop / Postal Store area (the "Buy Stamps" quick tool also leads there).
2. Browse the Stamps category, or search by keyword or SKU if you already know the issue you want.
3. Add the stamps to your cart and complete checkout. USPS.com supports account sign-in, and the site shows Register / Sign In options in its header.
4. Keep the order confirmation. After the order ships, you can use the Track a Package tool on usps.com with the tracking number to follow delivery.

What to expect: the Postal Store is a shopping flow separate from mailing tools like Click-N-Ship. Buying stamps there does not print postage for a specific package — it orders physical stamps that arrive by mail. If your goal is to pay for and print postage for one package right now, Click-N-Ship is the relevant tool instead.

Choosing the right stamp type

The Postal Store organizes stamps into consumer stamps, collectible stamps, and business supplies. Match the type to your use:

If you are unsure which denomination covers your mailpiece, use the Calculate a Price tool on usps.com before ordering so you buy enough postage.

Buying stamps in person

Post Offices and approved retail locations sell stamps over the counter. This is the option to choose when you need stamps immediately, want to pay in person, or prefer to ask staff which stamp fits your mailing. The Find USPS Locations tool on usps.com helps you locate a branch. Availability of specific designs varies by location, so call ahead if you need a particular issue or a large quantity.

Using stamps after purchase

Once stamps arrive, apply them to the upper-right corner of the envelope. For packages, stamps can cover postage, but the total must meet the price for the service and weight — check with Calculate a Price first. If you underpay, USPS may return the item or require additional postage; the safer approach is to weigh the item and confirm the rate before mailing. For anything beyond a simple letter, Click-N-Ship lets you pay and print exact postage instead of combining stamps.

Tracking orders and handling problems

Stamp orders ship like other purchases, so use Track a Package with the number from your confirmation email. If an order arrives damaged, incomplete, or incorrect, the Postal Store's Returns & Exchanges information explains how to request a fix. For mail that was sent with insufficient postage, the recipient or sender may need to pay the difference — another reason to verify rates up front.

Quick decision guide

• Need stamps today, common denominations: go to a Post Office or retail counter.
• Want a specific design, collectible sheet, or bulk roll: order from the USPS Postal Store online and track the shipment.
• Mailing a package and want exact postage: skip stamps and use Click-N-Ship to pay and print postage.
