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.

SCACs

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.

Quotes

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.

Spot Quotes

ShipEngine API allows you to request a spot quote from an LTL carrier based on excess capacity. Some carriers do not support spot quotes.

Pickups

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 quote_id.

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.

Tracking

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.

Documents

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.
