LTL Carriers in ShipEngine
ShipEngine API provides many carrier options for LTL shipping and allows you to perform all your LTL shipping operations programmatically. There are some carriers, however, that do not offer all the ShipEngine API features programmatically, which means that we can't make them available to you in ShipEngine API. You will need to continue performing those operations using your existing processes. You can find information about which features are supported by each carrier below as well as a description of each feature.
LTL Carrier Information
The table below list information about the LTL carriers available in ShipEngine API. Click the heading for a description of the feature.
Each LTL carrier is uniquely identified in the industry by its Standard Carrier Alpha Code or SCAC. Some carriers even have multiple SCACs that correspond to different types of offerings. ShipEngine API also uses the SCAC to uniquely identify the carrier.
In ShipEngine API, the SCAC is referred to as the
carrier_code to streamline the terminology
used across different types of shipping carriers. You will need to know the SCAC for your LTL carrier for any request
that requires a
carrier_id. Likewise, many responses will include the
carrier_code, which corresponds to the SCAC.
ShipEngine API allows you to request a quote using contracted rates. Some carriers do not support requesting a quote programmatically. For those carriers, you can typically track shipments that you have shipped outside ShipEngine as well as retrieve shipping documents.
ShipEngine API allows you to request a spot quote from an LTL carrier based on excess capacity. Some carriers do not support spot quotes.
ShipEngine API allows you to programmatically request a pickup of your LTL shipment. You can provide all
the details about the shipment as well as your preferred container type and
accessorial services directly in the pickup request. If you'd like to know the cost in
advance, you may first
request a quote and then schedule a pickup using the
There are some carriers that do not support programmatically scheduling a pickup. However, you will still need to perform this operation in ShipEngine API, even if the carrier does not support programmatic pickup requests. This operation creates the bill of lading, which will be needed by the carrier at pickup. You will then need to schedule the pickup directly with the carrier.
ShipEngine API allows you to track your LTL shipment using the PRO number. The PRO number is returned when you schedule a pickup. However, some carriers don't support automatic PRO number generation. For those carriers, a PRO number will be assigned by the carrier at the time of pickup. The table above indicates which carriers support automatic PRO number generation.
ShipEngine API allows you to retrieve the documents related to your LTL shipment, including the bill of lading, invoice, delivery receipt, and weight inspection certificate.
