Frequently asked questions about creating labels and how postage fees work in ShipStation.
No. Your postage is purchased through your connected postage provider accounts, not through ShipStation.
In the case of ShipStation Carrier Services, Stamps.com is the postage provider. When creating a Stamps.com account in ShipStation, or using ShipStation Carrier Services, you'll be prompted to enter your credit card information during the setup process.
USPS postage providers (like Stamps.com) and ShipStation Carrier Services providers (like Hermes and DPD) charge you for the label at the time of label creation. The minimum purchase amount for these postage providers is $10/£10.
These providers also carry a balance. So, if your balance is less than the amount required to purchase a label (or labels), you will be required to purchase at least $10/£10. Any unused funds will be added to your balance for future label purchases.
ShipStation does not have the ability to print additional stand-alone postage to add to a package that has been returned for insufficient postage.
In order to reship an order that has been returned for insufficient postage, you must first void the label, then make the necessary adjustments to the shipment weight and print a new label.
If you use ShipStation V3, review the V3 Void Label article for the proper instructions.
ShipStation's focus is on small parcel shipping, so this will depend on which postage providers you have connected to ShipStation and if that provider supports letter postage through ShipStation.
In most cases, the answer is no. However, if the letter postage service and package type for your selected provider are available in ShipStation, you can select them and print the postage just as you would for a small parcel.
Keep in mind that all labels printed from ShipStation are 4 in x 6 in labels, which are not always appropriate for letter-sized envelopes.
To print letter postage using a Stamps.com or other USPS provider account, choose USPS First Class Mail from the Service menu, and Letter from the Package menu.
Every label that is created in ShipStation is stored in our system for 180 days. During that time, you can reprint the label at no extra charge.
If you ever need documentation of a shipping label you created through ShipStation (to file an insurance claim, for example), please open a support case with us and include the order number and/or tracking number. Support will then send you a copy of your transaction details.
No. Once you void a label that label is no longer valid and it cannot be unvoided. However, if you need the label after voiding it, you can create a new one.
Some selling channels will not accept a second tracking number from ShipStation. If that is the case, you may want to manually update the new tracking number on your selling channel for that order.
You can ship to PO Box addresses in ShipStation when using USPS services. Most other carriers do not deliver to PO Boxes. However, UPS Surepost and FedEx Smartpost services do support PO Box delivery, since USPS carries the package to its final destination.
FedEx and UPS PO Box Alerts
ShipStation will return an alert when attempting to created a FedEx label for a PO Box address, and no label will be created.
UPS, on the other hand, does not return an alert and will allow you to create the label even though they will not deliver to the PO Box. In this case, ShipStation will alert you that you are attempting to ship to a PO Box in the Cost Summary screen so you can select a different service before creating a label.
To add information like item SKU, order number, or PO Number to a label, use ShipStation's Label Messages feature.
Label Messages Not Supported by All Carriers
Not all carriers support label messages. To find out if your selected carrier supports adding messages to its labels, please review the carrier's Integration article in our Integration Help guide.
If you have multiple USPS postage providers connected to your ShipStation account, ShipStation can display the USPS service options in two ways:
By postage provider: This option will list each postage provider in the Service drop-down menu with all of their active services so you can choose a specific service from a specific provider.
By carrier: This will list all available USPS service options under the single heading USPS.
If you have enabled ShipStation to optimize your USPS rate selection, ShipStation will automatically choose the USPS postage provider with the lowest rate for your selected service.
To enable rate optimization, go to
Settings > Shipping > Carriers & Fulfillment, click Manage USPS Rate selection options, and check the box for Always optimize my USPS rate selection.
To change how your services list is displayed, click the action menu next to the Service drop-down menu:
If this action menu is not present, that means you do not have multiple USPS providers connected to your ShipStation account.
Here is an example of how your Service drop-down menu will look for each option:
By default, ShipStation does not display postage fees on labels unless there is a requirement in place by the carrier. This may be required due to the destination country (like Brazil), or due to service or carrier insurance requirements.
The USPS requires postage to display on the label when you purchase carrier insurance. To avoid this, use Shipsurance as the insurance for your shipments instead.
In all other cases, the cost you paid for the postage will not print on the label. Instead, you can tell ShipStation that you do want the postage to print on the label. This setting is located in the Other Shipping Options section of the Order Details.
While there is not currently a Tube package type available in ShipStation, Stamps.com recommends using the package type Package for these shipments and entering the appropriate tube dimensions to ensure labels are charged the proper rate.
This is true whether you are using your own custom packaging or the USPS provided Dual-Use Priority and Priority Mail Express tubes.
Below you'll find information specific to USPS First Class and Priority services using tubes. For each service, the same weight and size restrictions that apply to packages also apply to tubes.
USPS First Class Mail
The rate is determined by the weight of the package.
Height and width will be the same.
USPS Priority Mail
Priority Mail uses zone-based pricing. That means for certain zip codes you will have to enter the dimensions of your tube in order to obtain the correct rate. Incorrect dimensions can result in packages being returned, or rate adjustments applied to your postage provider account after shipping.
Review the USPS guide to help determine the girth of your package.
USPS Dual-Use Tubes
If you ship using the small or medium Priority Mail or Express tubes provided by the post office, you will still select package type Package and enter the dimensions for the tubes into ShipStation.
To see how much a specific label cost:
Go to the Shipments tab and locate the shipment.
Locate the Carrier Fee column in the Shipments grid.
If you do not see the Carrier Fee column, go to the Columns drop-down menu and check the box next to Carrier Fee to add that column to your grid. ShipStation adds new columns to the right end of the screen, so you may have to scroll to the right to view it (click and drag the column to move it to another location).
The Shipping Sidebar and Order Details screens do not store the cost of your label in the Rate field. This field only displays the rate for the whatever you have configured in the above settings, which can be changed at any time. For this reason, we do not recommend relying on the Rate field in an order.
If you need a receipt for a specific label you purchased, locate the shipment in ShipStation's Shipments tab and copy the tracking number. Then, contact ShipStation support, request a Transaction Details Report, and provide the tracking number for each shipment you need the receipt for.
Support will attach each Transaction Details Report to their response.
Yes! In ShipStation, this is called a third-party account.
To assign a third-party account to an order:
Set the shipping service and package type for the order.
Since ShipStation requires you to first select the correct service, this means you must already have your own carrier account connected to ShipStation.
For example, to bill to a recipient's UPS account, you must have your own UPS account connected to ShipStation, then select a UPS service for that order.
Go to Other Shipping Options in the Shipping Sidebar and click the Shipping Account drop-down.
ShipStation Classic Other Shipping Options:
ShipStation V3 Other Shipping Options:
Choose either Third Party or Recipient from the list.
Enter the third party Account #, Billing Country, and Billing Zip (Postal Code).
Create the label.
ShipStation will send the billing details to the selected carrier, and the carrier will pass on the billing to the correct account.
If this is something you will do regularly, consider using Automation Rules to automatically apply third party billing to your orders. Be sure the rule first sets the shipping service and package type correctly, then adds the third-party account details!
The Recipient and Third Party designations are for information and reporting purposes only. Either option will tell the carrier to charge the entered account.
The third party account must be approved by the carrier for third party billing. If you receive an error when attempting to create a label with third party billing, check with the account owner to ensure it has been approved by the carrier.
Integrated labels are labels that print with the packing slip on the same sheet. If you are using Integrated labels with the 8.5" x 11" label w/ packing slip format (pictured below), ShipStation by default prints the label on the top portion of the page.
However, if you are shipping multiple packages for a single order (what we call a Multi-package shipment), all of the labels associated with the order will print first, regardless of which side of the paper they are printing.
This can cause the packing slip to be pushed down to the last page, and not print in the integrated way you may have intended.
However, you can send a request to our support team to set your account so the label always prints labels at the top of the page.
Once we enable the labeltop feature for you, ShipStation will always print your label on the top portion of the page and the packing slip on the bottom. This will result in the final label printed always being integrated with the packing slip for that order.
Please contact ShipStation Support if you'd like this option to be enabled on your account.
