An Introduction to SCAC Codes

Intermodal freight is one of the most widely used modes of transport around the world. One container can travel via rail, road, and maritime without being unloaded until it reaches its final destination. This method saves time and is highly economical compared to other forms of shipping.

To keep track of the millions of containers in transit across the globe, freight companies rely on a system known as the Standard Carrier Alpha Code (SCAC). This system assigns unique codes to identify containers and streamline logistics operations.

What is a SCAC Code and Why is it Important for Freight Shipping?

A Standard Carrier Alpha Code (SCAC) is a unique, four-letter code that identifies intermodal containers, primarily those used by Vessel Operating Common Carriers (VOCC). These codes are critical in tracking shipments, particularly in international and intermodal shipping.

SCAC codes typically allow a privately owned freight line to be identifiable by computer systems and other tracking types, including the American National Standards Institute (ANSI), Accredited Standards Committee X12, and United Nations EDIFACT systems.

Benefits of SCAC Codes: 

• Improves tracking: SCAC codes allow companies to track shipments electronically across different modes of transportation.

• Increases security: Using standardized codes ensures each shipment is uniquely identifiable, reducing the risk of errors or loss.

• Streamlines logistics: SCAC codes integrate with various logistics software, enhancing operational efficiency.

Who Uses SCAC Codes?

SCAC codes are essential across a wide range of industries, especially those that rely heavily on intermodal and international freight. Key industries include:

Petroleum: SCAC codes are crucial for tracking fuel shipments, ensuring that products reach their destination securely and on time.

Automotive: Automakers and parts suppliers use SCAC codes to track components as they move through the supply chain, often by rail or truck.

Forestry: Paper products and other forestry materials are frequently shipped in double-stacked railcars, making SCAC codes vital for efficient tracking.

Chemical Industries: Chemicals require strict handling and tracking protocols, and SCAC codes ensure that these shipments are traceable from origin to destination.

Retail: Many large retailers, including those in e-commerce, rely on SCAC codes to manage the logistics of importing and distributing products.

International freight companies use SCAC codes to easily identify shipments with specific shipping lines, speeding up processing and enhancing security. In the maritime industry, every container on a ship is assigned a SCAC code, which links it to the shipping company responsible for the cargo.

Freight transportation companies, particularly those that are part of the Uniform Intermodal Interchange Agreement (UIIA), must have a SCAC code. Membership in the UIIA requires SCAC codes to facilitate intermodal operations across multiple transportation modes, such as road, rail, and sea.

How are SCAC Codes Used?

SCAC codes keep track of containers electronically. This coding is a uniform system that most freight lines worldwide use to ensure their containers are en route to the proper destinations. This system also allows customers to track their shipments.

SCAC Code Symbols

The letters in the SCAC code represent a particular mode of transportation and the owner of the container. When the last letter of the code is "X," that means the container belongs to a railroad company, such as CSX Transportation.

Codes ending with a "Z" are owned by trucking companies or other organizations. These are common in identifying truck chassis and trailers used in intermodal service on either trucks or trains.

For example, let’s take a look at some of the most common types of SCAC codes used by various private entities:

Who needs a SCAC Code?

SCAC codes are required for various companies across multiple sectors. Here are some examples of industries that rely on SCAC codes. 

• Intermodal Freight Companies: Any company involved in intermodal transportation or those filing tariffs with the Surface Transportation Board (STB) must have a SCAC code for efficient tracking and regulatory compliance.

• International Carriers: Companies that transport goods internationally need a SCAC code to link shipments to the appropriate freight company, ensuring smooth customs processing and tracking.

• FDA-Regulated Shipments: Businesses shipping goods regulated by the Food and Drug Administration (FDA), such as imported foods, must use a SCAC code with the Prior Notice System Interface (PNSI) to track and monitor these shipments.

• Government Freight Contractors: Any carrier providing freight services to the U.S. government is required to have a SCAC code for compliance and logistics management.

• Petroleum Industry: In the petroleum sector, SCAC codes are essential for tracking containers and integrating with software that manages bills of lading, product transfer orders, pipeline tickets, and inventory tracking.

How to Obtain a SCAC Code

Private transportation companies who want to begin shipping via intermodal freight must obtain a SCAC code. Getting a SCAC code is a fairly straightforward process. New shipping or logistics companies may register for a SCAC code by following these steps:

1. Visit the NMFTA Website: Go to the National Motor Freight Traffic Association's website. NMFTA is the governing body responsible for issuing SCAC codes.

2. Complete the Registration: Fill out the required forms with your company's details.

3. Pay the Fee: An application payment is required to complete the registration process.

4. Receive Your SCAC Code: Once you've completed the registration and paid the fee, you should receive your SCAC code. If needed, use this link to check your SCAC application status.

Please note: SCAC codes need to be renewed annually. Your renewal date is 365 days from the date you were assigned the SCAC code. You can renew your SCAC code through the NMFTA website.
