What it does
Shipping by hand means copying addresses into a separate postage site, checking rates and printing labels one order at a time. That takes time and invites typos. This extension links WooCommerce with Stamps.com so labels are generated from the order data you already have. You get discounted USPS rates, including Priority Mail and Priority Mail Express pricing with no minimum volume, and you can add discounted package insurance to shipments.
Everything happens inside the WooCommerce admin. You can view labels, request label refunds, delete labels you no longer need and top up your Stamps.com account without switching tabs. Address verification checks shipping details to cut down on failed deliveries. Labels can also be created for UPS and other carriers. If you also run the USPS Shipping Methods extension, shoppers can see discounted USPS rates at checkout. The plugin requires WooCommerce.
Best for
- WooCommerce stores that ship most orders with USPS
- Small online shops tired of creating labels by hand
- Warehouses printing labels for large daily order volumes
Features
Automatic USPS label creation
Generate ready-to-print USPS shipping labels straight from your WooCommerce orders, so you skip retyping addresses and package details into another tool.
Discounted USPS postage
Ship at reduced USPS rates compared to retail pricing, including Priority Mail and Priority Mail Express, with no minimum shipping volume required.
Live postage rates
Pull current USPS postage costs directly from Stamps.com, so the amount you see when creating a label reflects up-to-date pricing.
Address verification
Check shipping addresses for accuracy so packages are less likely to be delayed or returned because of a mistyped street or postal code.
Label management in admin
View labels, request refunds, delete labels and add funds to your postage account from the WooCommerce dashboard without logging in elsewhere.
Multiple carrier support
Create shipping labels for UPS and other carriers as well as USPS, which helps stores that use more than one shipping service.
Discounted package insurance
Add insurance to shipments at a lower rate than standard USPS insurance, giving your packages protection at a reduced cost.
Works with USPS Shipping Methods
Pair it with the USPS Shipping Methods extension to show customers discounted USPS rates during checkout.

Questions about WooCommerce Stamps.com API integration
Can I print shipping labels without leaving WooCommerce?
Yes. Labels are generated from your WooCommerce orders and are ready to print. You can also view, refund and delete labels and top up your Stamps.com account from the same admin area.
Does it only work with USPS?
USPS is the main focus, with discounted postage and insurance. You can also create labels for UPS and other carriers, which is useful if your store ships through more than one service.
Do I need to ship a large volume to get the discounted rates?
No. Discounted USPS Priority Mail and Priority Mail Express rates are available without a minimum volume requirement, so shops sending a few packages a day can use them as well as high-volume shippers.

That works when you combine this plugin with the USPS Shipping Methods extension. Together they display discounted USPS rates to shoppers during checkout so they know their shipping cost before paying.
