ShipEngine Carriers

ShipEngine Carriers gives you one payment method that can buy labels from multiple carriers. Currently, ShipEngine Carriers includes USPS and UPS service providers.

ShipEngine Carriers works like a single postage account in ShipEngine for you to create labels and have access to our select rates for services with preferred shipping associates. There’s no need to create individual accounts with them. With ShipEngine Carriers, you set up the billing method you wish to use and purchase your labels.

  2. Configure your preferred funding settings. For example, if you wanted to purchase $100 any time your account balance is below $250, set the When balance drops below amount to ‘250’ and the Automatically fund by this amount to ‘100’.

Cubic Pricing


Cubic pricing is available by default for all ShipEngine users creating labels with ShipEngine USPS.

Cubic rates are ideal for small, heavy packages since the pricing is based on the volume of the package instead of the weight. Any package that measures 0.50 cubic feet or less and is 20 pounds or less is eligible.

To receive cubic rates in ShipEngine:

  1. Choose a USPS domestic Priority service.
  2. Choose a package type of Package.
  3. Enter the package weight & dimensions.

ShipEngine will automatically apply the cubic rate whenever it's cheaper than the priority rate.

In addition to being able to manage multiple carriers from one postage account, ShipEngine Carriers gives you access to discounted rates from both USPS and UPS, including cubic pricing for USPS shipments!
