Global Advantage Program

Explanation of Global Advantage Program (GAP), which applies to international shipments using First Class or Priority services.

The Global Advantage Program (GAP) is an international shipping program through that provides an economical way to ship merchandise internationally.

ShipStation users have access to two types of GAP services:

  • Global Advantage Program Single Label

  • SmartSaver

Global Advantage Program - Single Label

When printing single USPS international labels for First Class or Priority services with your account, ShipStation automatically prints a GAP label.

GAP benefits include:

  • Up to 65% in savings over the retail USPS Package shipping cost

  • No need to print Customs Declaration forms

  • No need to change your workflow in ShipStation

How it Works

Similar to many international consolidators, you first send your packages via USPS to a domestic sorting facility. There, your international shipments are relabeled for their destination, receive their appropriate customs forms, and are then sent on to their final destination.

This means the label you print will be a domestic label addressed to the Postal Processing facility instead of the final destination.

If you have a account, you are automatically enrolled in the Global Advantage Program.

Review the Global Advantage Program section of our article to learn how to create and use GAP labels.


For businesses that ship 5 or more international shipments a week, the Global Advantage Program offers additional savings!

With the SmartSaver service, you consolidate all your individual international parcels into a single, large container. You then send the large container to the sorting facility where the individual shipments will be sorted and sent on to their final destination.

By printing a GAP SmartSaver label with a scan code, the tracking for all included shipments will update when the large package gets scanned.


  • At least a 10% discount on USPS international rates.

See the Global Advantage Program section in our article for instructions on how to print labels for a consolidated shipment.

Notes about the Global Advantage Program

  • The international tracking number on the GAP label will track the package to the sorting facility and may track the package to the destination country as well, depending on the country.

  • If you receive an error in the Rate field in ShipStation or when you attempt to create a label:

    You may have a account with a negotiated service agreement. If this is the case, your (or Endicia) account may not be eligible for the Global Advantage Program. Please contact your or Endicia representative for further information.
