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.
