Can you buy USPS shipping label online?
Yes. With Label Shark, you can buy a USPS shipping label online and compare it with other available carrier options before you pay. That helps you see whether USPS is the best fit for your shipment or whether another service may work better for your package and destination.
The process is simple: enter shipment details, compare available rates, choose a service, add customs information if your shipment requires it, pay securely, print the label, and drop off the package with the selected carrier.
Shipping cost is not one fixed number. It usually depends on package weight, dimensions, destination country, service level, and which carriers are available for that shipment.
Use the rate calculator above to compare services and buy your label.

Drop off the package
Take the package to the selected carrier's drop-off location or handoff point. The package should be dropped off with the same carrier shown on the label.
If you are shipping internationally from the United States, be ready to complete customs details before buying the label.
USPS and other carrier options you may see
If you want to buy USPS shipping label online, USPS may be a strong option for many shipments. Label Shark may also show DHL, UPS, and FedEx services where available so you can compare choices side by side instead of guessing.
| Carrier | Best for | Notes |
|---|---|---|
| USPS | Common parcel and document shipments, especially when you want a familiar postal option | Availability depends on package details and destination. Some shipments may still compare better with another carrier depending on service level and destination. |
| DHL | Many international shipments where broad global coverage is important | Often considered for international delivery options. Service availability and pricing depend on destination, package characteristics, and customs requirements. |
| UPS | Parcels where you want to compare courier services and service-level choices | May be useful for a range of shipment types. Exact rates and options vary by package size, weight, and destination. |
| FedEx | Shipments where you want another major carrier option for comparison | Can be worth comparing for both documents and merchandise. Availability depends on route, package details, and service rules. |
The best option is the one that fits your package, destination, and timing needs. The calculator helps you compare what is actually available for your shipment.
Customs information for international shipping labels
For international shipments from the United States, customs information is usually required. This helps carriers and border agencies understand what is inside the package and how it should be processed.
You may need to enter a clear item description, declared value, country of origin, shipment purpose, and whether the contents are documents or merchandise. Some shipments may also require an HS classification or supporting customs details.
Label Shark supports customs entry during the label-buying flow, and AI-assisted classification help may be available where relevant. You should still review all customs information carefully before payment.
Customs processing, duties, taxes, and import requirements depend on the destination country and the contents of the shipment. Label Shark does not provide legal or tax advice and cannot guarantee customs outcomes.
- Item description
- Declared value
- Country of origin

Incomplete or inaccurate customs details may cause delays, extra charges, or delivery problems.
If you are unsure how to describe the contents, use specific plain language and avoid vague terms.
Important things to know before you buy a label
Use accurate weight and dimensions
Estimated measurements can lead to incorrect rates or carrier adjustments. Weigh and measure the packed box or envelope as it will actually ship.
Check sender and recipient addresses carefully
A small address error can cause delays, returns, or failed delivery attempts. Use complete and correct address details before checkout.
Write clear contents descriptions for international shipments
If customs applies, avoid vague descriptions like "gift" or "parts" by themselves. Be specific about what is inside the package.
Include phone or email when required
Some international services or destinations may require contact details for delivery or customs communication.
Check prohibited and restricted items
Carrier rules and destination-country rules may limit what can be shipped. Make sure your package contents are allowed before buying the label.
Drop off with the selected carrier
If you buy a USPS label, the package should go to USPS. If you choose DHL, UPS, or FedEx, use that carrier's drop-off network.
The label is generated after payment
Once checkout is complete, your shipping label is created and ready to download and print.
Taking a minute to verify the shipment details usually helps avoid the most common label and delivery problems.
