SCAC for Intermodal Trucking
What is the Standard Carrier Alpha Code (SCAC) and Why Do I Need It for Intermodal Trucking?
The Standard Carrier Alpha Code (SCAC) is a unique two-to-four-letter code assigned to transportation companies by the National Motor Freight Traffic Association (NMFTA). A SCAC identifies a motor carrier, trucking company, railroad, ocean carrier, or logistics provider in transportation systems throughout North America.
For companies involved in intermodal freight, drayage operations, container transportation, and port trucking, a SCAC is often required before you can move freight through ports, rail terminals, shipping lines, and intermodal facilities.
If you plan to haul containers through facilities such as the Port of Charleston, Port of Savannah, Port of Jacksonville, Port of Houston, or the Port of Virginia, obtaining a SCAC is usually one of the first administrative requirements you will encounter.
What Is a SCAC?
The Standard Carrier Alpha Code is essentially an identification number for transportation companies.
Unlike a DOT Number or MC Number issued by FMCSA, a SCAC is specifically used by freight systems, ports, railroads, steamship lines, brokers, and logistics providers to identify carriers electronically.
A SCAC is generally:
- Two to four letters long
- Unique to each transportation company
- Issued by the NMFTA
- Used throughout North America
Examples include codes assigned to major trucking companies, railroads, ocean carriers, and freight providers.
Why Was the SCAC Created?
The transportation industry needed a standardized way to identify carriers across different shipping platforms.
Before SCAC codes became common, transportation companies were identified using company names, which often created confusion because:
- Companies had similar names
- Businesses changed names
- Multiple divisions existed within one organization
- Data entry errors were common
The SCAC system created a uniform identifier that could be used across shipping systems.
Why Do Intermodal Trucking Companies Need a SCAC?
One of the most common questions new authorities ask is:
Why do I need a SCAC for intermodal trucking?
Most intermodal operations require a SCAC because shipping lines, railroads, and ports use the code to identify the motor carrier handling containers.
Without a SCAC, a trucking company may not be able to:
- Register with ports
- Access rail terminals
- Receive container releases
- Work with steamship lines
- Participate in intermodal freight programs
- Complete certain UIIA registrations
For many intermodal carriers, a SCAC is mandatory.
SCAC vs DOT Number
Many trucking companies confuse SCAC codes with DOT Numbers.
They serve different purposes.
DOT Number
A DOT Number is issued by FMCSA and is used for:
- Safety monitoring
- Regulatory compliance
- Inspections
- Audits
SCAC
A SCAC is used for:
- Freight identification
- Container release systems
- Port access
- Rail terminal operations
- Shipping documentation
Most intermodal carriers need both.
SCAC vs MC Number
A Motor Carrier (MC) Number is another identifier that differs from a SCAC.
MC Number
Used for:
- Operating authority
- Interstate trucking authority
- Regulatory compliance
SCAC
Used for:
- Freight transactions
- Electronic data interchange systems
- Port operations
- Railroad systems
A trucking company may have:
- DOT Number
- MC Number
- SCAC Code
All three serve different purposes.
Who Requires a SCAC?
Many organizations require a SCAC before allowing freight movement.
These may include:
- Steamship lines
- Port authorities
- Railroads
- Freight brokers
- Third-party logistics providers
- Container leasing companies
- Government agencies
Without a valid SCAC, container movement can be delayed or denied.
Ports Where SCAC Codes Are Commonly Required
SCAC registration is common at major intermodal ports.
South Carolina
The Port of Charleston relies heavily on electronic carrier identification systems.
Many drayage carriers serving Charleston maintain active SCAC registrations.
Georgia
The Port of Savannah uses carrier identification systems that frequently require SCAC information.
Florida
Major Florida ports include:
- Port of Jacksonville
- Port of Miami
- Port Everglades
These facilities often require carrier identification for container operations.
Texas
Major Texas freight hubs include:
- Port of Houston
- Port of Galveston
SCAC codes are routinely used in intermodal freight transactions.
Virginia
The Port of Virginia is one of the busiest East Coast container gateways and frequently utilizes SCAC-based identification systems.
Pennsylvania
Intermodal freight moving through Philadelphia and major rail facilities often requires carrier identification through SCAC registration.
Do Owner Operators Need a SCAC?
The answer depends on the operation.
Many owner operators hauling standard freight may not need a SCAC.
However, owner operators involved in:
- Port drayage
- Container hauling
- Intermodal freight
- Rail operations
often need a SCAC to access freight opportunities.
Many steamship lines require the motor carrier’s SCAC before releasing containers.
How Do You Get a SCAC?
SCAC codes are issued by the National Motor Freight Traffic Association (NMFTA).
The application process generally includes:
- Completing an application
- Providing company information
- Paying the required fee
- Receiving the assigned SCAC
The code must be renewed periodically to remain active.
How Long Does It Take to Get a SCAC?
Processing times vary depending on application volume.
Many carriers receive their SCAC within several business days after submitting a complete application.
Expedited options may be available in some situations.
Can a New Authority Get a SCAC?
Yes.
Many new authorities obtain a SCAC shortly after receiving:
- DOT authority
- MC authority
- Insurance filings
New authorities planning to enter intermodal trucking often obtain a SCAC before beginning operations.
How Does a SCAC Relate to UIIA?
A SCAC and UIIA registration frequently work together.
Most intermodal carriers need both.
SCAC
Identifies the carrier.
UIIA
Confirms the carrier meets insurance and equipment interchange requirements.
Without proper insurance filings, a SCAC alone will not allow access to containers.
Likewise, UIIA compliance may not be sufficient if a steamship line requires an active SCAC.
Common SCAC Mistakes
Some common mistakes include:
- Allowing the SCAC to expire
- Using an incorrect SCAC on paperwork
- Failing to update company information
- Assuming a DOT Number replaces a SCAC
- Confusing MC authority with SCAC registration
These issues can create delays in container pickup and delivery.

Final Thoughts
Understanding what the Standard Carrier Alpha Code (SCAC) is and why you need it for intermodal trucking is essential for motor carriers operating in ports, rail yards, and container freight environments.
A SCAC serves as a unique identifier used throughout the transportation industry and is often required for container releases, port access, railroad transactions, and intermodal freight movement.
For trucking companies involved in drayage and container transportation, obtaining and maintaining an active SCAC is often just as important as maintaining proper insurance, FMCSA authority, and UIIA compliance.
