If you work with brokers, shippers, or ports, you may be asked for a SCAC code, and not having one can slow things down or block you from certain loads.
A SCAC code (Standard Carrier Alpha Code) is a unique identifier used to recognize transportation companies across shipping and logistics systems.
In this guide, you’ll learn what a SCAC code is, how it works, who needs one, and how to get it, so you can stay compliant and avoid delays.
What Is a SCAC Code?
A SCAC code is a two-to-four-letter identifier assigned to transportation companies by the National Motor Freight Traffic Association (NMFTA).
It’s used to identify carriers across documents, tracking systems, and electronic communication, without relying on full company names, which can be duplicated or misinterpreted.
In short, it’s a standardized way to make sure the right carrier is tied to the right shipment.
How Does a SCAC Code Work?
A SCAC code appears on key shipping documents like bills of lading, freight invoices, and manifests. It’s also used in Electronic Data Interchange (EDI) systems, where shipments are processed automatically between shippers, brokers, and carriers.
Because each SCAC code is unique, it eliminates confusion and helps ensure shipments are tracked, processed, and delivered correctly, especially in operations involving multiple carriers.
Who Needs a SCAC Code?
Not every business needs a SCAC code, but for many carriers, it becomes required as soon as they start working with larger networks.
You’ll likely need a SCAC code if you:
- Operate in interstate or intermodal shipping
- Work with freight brokers or large shippers
- Haul freight through ports, rail, or ocean carriers
- Need to integrate with EDI or logistics platforms
This applies to trucking companies, freight forwarders, logistics providers, and intermodal carriers.
For trucking companies, a SCAC code acts as a standard identifier that allows you to work with brokers, shippers, and government systems. In many cases, you won’t be onboarded or assigned loads without one.
Why Is a SCAC Code Required?
A SCAC code is required because it standardizes how carriers are identified across shipping systems, documents, and partners.
In practice, it’s what allows freight to move efficiently without confusion or delays.
Here’s why it matters:
- Standardized carrier identification
Eliminates confusion caused by similar or duplicate company names, especially when multiple carriers are involved. - Required for EDI systems
Used in automated systems that exchange data between shippers, brokers, and carriers. Without it, integration becomes difficult or impossible. - Needed for ports and government systems
Many ports, intermodal facilities, and agencies require a valid SCAC code for compliance and processing. - Faster, more accurate documentation
Reduces errors in bills of lading, invoices, and manifests, leading to fewer delays and smoother operations.
Without an SCAC code, carriers may face delays, limited access to certain freight networks, and challenges working with larger shippers or brokers.
Why Do You Need a SCAC Code for Trucking?
In trucking, a SCAC code isn’t just an identifier. It’s often required to work with brokers, shippers, and larger logistics networks.
It allows your business to integrate into digital systems and makes it easy for partners to identify and verify your company across documents and platforms.
Without an SCAC code, you may run into delays, onboarding issues, or miss out on contracts, especially when working with larger clients.
What Are the Benefits of SCAC Codes?
A SCAC code helps you move freight more efficiently and makes it easier to work with brokers, shippers, and larger networks.
Key benefits include:
- Faster processing
Standardized identification means shipments move through systems more quickly with fewer delays. - Fewer errors in paperwork
Reduces mistakes in bills of lading, invoices, and tracking by clearly identifying the correct carrier. - Seamless system integration
Required for EDI and logistics platforms, allowing smoother communication between partners. - Stronger credibility
Signals that your business meets industry standards, making it easier to work with brokers and regulated entities. - Access to more freight opportunities
Many large shippers and networks require a SCAC code before onboarding carriers.
How Do I Apply for an SCAC Code?
Applying for an SCAC code is a simple process handled by the National Motor Freight Traffic Association (NMFTA).
Steps to Apply for a SCAC Code
1. Complete the application
Visit the NMFTA website and fill out the SCAC application form online.
2. Provide your company details
Enter your business name, address, and type of operation (trucking, intermodal, brokerage, etc.).
3. Pay the application fee
Submit the required fee during the application process.
4. Submit for review
Once completed, NMFTA will review your application and assign your SCAC code.
5. Receive your SCAC code
After approval, you’ll get your code and can start using it immediately in shipping documents and systems.
Note: SCAC codes must be renewed annually to remain active.
Who Can Help You Get a SCAC Code?
While applying for a SCAC code is straightforward, some carriers choose to use third-party compliance services to handle the process.
These providers can:
- Submit the application on your behalf
- Ensure all details are accurate
- Manage renewals
This can be especially helpful for new carriers already handling multiple registrations, like USDOT numbers and MC authority.
What Is a SCAC Code List?
A SCAC code list is a directory of registered carriers and their assigned codes.
It’s used across the logistics industry to quickly verify and identify carriers when processing shipments.
Because each SCAC code is unique, these lists help prevent confusion and ensure accuracy in documentation and tracking.
SCAC Lookup: How to Check a Carrier’s Code
To verify or find a SCAC code, use a SCAC lookup tool or database.
Simply search by carrier name to retrieve the correct SCAC code.
This is useful when working with new partners or confirming details before processing shipments, helping you avoid errors or delays in documentation.
SCAC Codes: What It Comes Down To
A SCAC code is a standardized identifier used to track and verify carriers across shipping systems.
In many cases, it’s required to work with brokers, shippers, ports, and larger logistics networks—without one, you may face onboarding delays or miss out on certain freight opportunities.
The application process is quick through NMFTA, but the code must be renewed annually to remain active.
Frequently Asked Questions
How Long Does It Take to Receive A SCAC Code?
In most cases, carriers receive their SCAC code within a few business days after submitting a complete application. However, processing times can vary depending on the accuracy of the information provided and the volume of applications being handled.
Is the SCAC code mandatory?
A SCAC code is not legally required for all carriers, but it becomes mandatory in certain situations. For example, working with specific clients, ports, or government systems may require a valid SCAC code for identification and compliance.
Is the SCAC code required for the ocean container industry?
Yes, SCAC codes are widely used in the ocean container industry. Ports and terminals rely on them to manage shipments, track containers, and ensure smooth coordination across global logistics networks.
How much is a SCAC code?
The cost of obtaining a SCAC code typically ranges between $75 and $100 per year. Since it requires annual renewal, carriers should consider it a recurring compliance cost as part of their operations.
