What Pirate Ship actually is
Pirate Ship is a free postage-buying platform: no monthly fee, no per-label markup, no volume minimums. You create an account, enter a package's weight, dimensions, and destination, and it sells you real USPS or UPS postage at the deep commercial pricing normally reserved for high-volume shippers. The business model is simple — carriers pay Pirate Ship a cut of postage sold, so the discounts get passed through instead of gated behind a subscription.
To be clear about what this page is: we're not Pirate Ship, and we're not competing with it. Pirate Ship sells postage; this site formats labels. Plenty of sellers use both — and if you're deciding where each fits, the sections below map the boundary honestly.
The services it sells — and why Cubic matters
Through Pirate Ship you can buy USPS Ground Advantage, Priority Mail, Priority Mail Express, Media Mail, and international services, plus discounted UPS Ground and air services. The headline saver for small heavy packages is USPS Priority Mail Cubic — a pricing tier based on box volume instead of weight, normally invisible to casual shippers, that Pirate Ship surfaces automatically whenever your package dimensions qualify.
A dense package in a small box — books, canned goods, hardware, cosmetics — can ship Cubic dramatically cheaper than weight-based Priority Mail. If your products are small and heavy and you've never priced Cubic, that single tier is reason enough to open a Pirate Ship account.
💡 Cubic pricing applies to packages up to 20 pounds and 0.5 cubic feet. Measure your box honestly — a quarter inch of bulge past the tier boundary bumps the price bracket.
What Pirate Ship doesn't do
The boundaries are clean: Pirate Ship sells USPS and UPS only — no FedEx, no DHL Express. Every label it produces requires purchasing postage in the same step, so there's no way to generate a formatted label without buying; that rules out draft labels for address proofing, internal routing labels for a stockroom, or labels where postage is being handled by someone else (a company shipping account, a prepaid return program, a freight forwarder's instructions).
None of these are criticisms — they're scope. Pirate Ship is a postage store, and it's an excellent one. But 'I need a label' and 'I need postage' are only sometimes the same sentence.
Where this label maker fits alongside it
Everything in the previous section is what this tool covers. Need a FedEx- or DHL-formatted label because your account or your buyer's is paying carriage? Format it here. Want a draft label to verify a suspicious address layout before committing postage? Print one free. Shipping under a corporate carrier account where postage never touches your wallet? Generate the label, apply the account's tracking, done.
The combined workflow many sellers land on: design and proof the label here (correct address block, reference numbers, FRAGILE marks), then buy the actual USPS/UPS postage on Pirate Ship for anything it covers, using its label for the shipment itself. Each tool does the thing it's built for.
International shipments and the Simple Export Rate
Pirate Ship handles international USPS services and offers its Simple Export Rate for lightweight worldwide packages, with customs forms built into the label purchase flow — you enter contents, values, and origin, and the declaration prints with the label. For sellers exporting regularly through Pirate Ship, that integration is the right path.
Where our tool intersects internationally: label formatting for carriers Pirate Ship doesn't broker (DHL Express is the big one for time-sensitive exports), and address-block formatting for countries with layouts that trip up US sellers — postal codes before cities, prefecture lines, non-Latin address elements. Format here, then hand the package to whichever carrier your postage came from.
