What Is a SCAC Code and How Is It Used?

A Standard Carrier Alpha Code (SCAC) is a unique identification number that is attributed to registered freight carriers.

The National Motor Freight Traffic Association Inc (NMFTA) requires all freight containers and carriers entering and operating in the US to have a Standard Carrier Alpha Code or SCAC code to properly identify transportation companies.

This code is required for automated information computer systems, and it offers the ability to quickly identify, track, and manage freight shipments. If you’re new to the transportation industry, here’s all you need to know about SCAC codes.

What is a SCAC code? 

A SCAC code stands for Standard Carrier Alpha Code, a coding system set forth by the National Motor Freight Traffic Association (NMFTA).

A unique two- to four-letter code is assigned to all the transportation companies entering and operating in the United States to identify carriers through:

  • electronic data interchange (EDI) transactions
  • intermodal interchange agreements (such as the UIIA)
  • computerized, freight-and-passenger-transportation payment systems (Cass Information Systems, CorPay Solutions, Inc., etc.)

Who needs a SCAC code? 

All freight carriers and transportation companies entering and operating in the United States need the relevant SCAC codes to comply with the NMFTA regulations. This also includes any shipper using a third-party carrier and broker services that require a unique code.

However, an exception goes for codes used to identify freight containers not operating exclusively in North America, Intermodal Chassis and trailers, privately owned railroad cars, and railroads.

Is the SCAC code mandatory?

Regarding the following, yes. Government agencies have mandated the use of SCAC codes:

  • United States Bureau of Customs and Border Protection (CBP) for its Automated Manifest System (AMS), Pre-Arrival Processing System (PAPS), and Automated Commercial Environment (ACE) System.
  • Food and Drug Administration (FDA) Prior Notice System Interface (PNSI) for properly tracking imported food

The SCAC code is also mandatory for all commercial transportation companies and freight carriers doing business with US government agencies to transport petroleum products, forest products, automobiles, and chemicals.

A SCAC code is also required for freight carriers who utilize the Uniform Intermodal Interchange Agreement (UIIA, which is also known as the Intermodal Association of North America (IANA).

This also includes vessel-operating common carriers, intermodal equipment, and freight forwarders.

Is the SCAC code required for ocean container industries?

Yes, the SCAC code is required for ocean carrier industries and any other industry that requires an EDI transaction. The same process for obtaining a SCAC code applies to ocean carriers.

How do SCAC codes work in logistics and shipping?

In logistics and shipping, the unique SCAC code provided by the NMFTA ensures that the goods are properly identified during transit. Typically, the process is:

  • The shipper enters the SCAC code provided by the carrier and submits it to their customer. This acts as confirmation of the contracted carrier.
  • The customer uses this code to track the progress of the goods.
  • When the goods arrive at their destination, the customer can use this code to identify them.
  • The SCAC code is also used by customs to ensure that they are dealing with a legitimate carrier.

How do I get a SCAC code?

If you need assistance with the SCAC code application, it can be done online via DOT Compliance Group’s website. You only need to provide your:

  • carrier company information
  • Federal Motor Carrier Safety Administration (FMCSA) information: US-DOT number, MC number, MX number, FF number, etc.

Your SCAC code will then be provided within 24 hours during business days.

How much is a SCAC code?

The cost for new SCAC code applications can vary depending on which service you use.

When do you renew your SCAC code?

For new applications, you have the option to subscribe to auto-renewal. Each SCAC code is due for renewal 365 days from the assignment date.

SCAC Code list 

The SCAC code list is published by the National Motor Freight Traffic Association (NMFTA). It’s available through the SCAC Online website, although you need an account to access it.

What is EDI shipping?

Electronic Data Interchange (EDI) shipping is a process that allows companies to exchange shipping documents electronically.

It’s used most commonly in the transportation industry to transmit data between shippers, carriers, and third-party logistics providers.

What are considered EDI documents?

EDI documents include but are not limited to the following:

  • Bill of lading: an agreement between a shipper and a carrier for the transportation of goods
  • Freight invoice: billing information sent to customers who pay for the freight shipped
  • EDI manifests: a list of products that are being shipped from one location to another
  • Proof of delivery (POD): a document verifying that the goods have been delivered to their destination
  • Purchase orders: an order from a buyer to the seller to purchase goods
  • Electronic import customs clearance: a document that allows customs authorities to clear goods for import quicker

For each EDI document, the SCAC code is required. Using a SCAC code, the EDI document can be tracked and processed quickly and efficiently.

SCAC codes and EDI integration in supply management

SCAC codes are essential for efficient supply chain management. They help streamline operations by allowing organizations to accurately identify and track shipments without manually entering data.

The use of SCAC codes and EDI shipping facilitates communication between shippers, carriers, customs agencies, and other stakeholders in the supply chain.

It helps eliminate paperwork and reduce costs associated with manual processes, which leads to improved customer service and satisfaction.

Use a SCAC code and integration to automate shipping 

The Standard Carrier Alpha Code (SCAC) is an important part of the transportation industry. Coupled with EDI integration, SCAC codes can help automate the shipping process, making it faster and more efficient.

By using a SCAC code and EDI integration, shippers can have peace of mind knowing that their goods are in safe hands and will be delivered on time.

FAQ

What Happens If You Fail a DOT Inspection?

If the vehicle or driver is deemed unsafe, they may be placed out of service, meaning the vehicle cannot operate until all violations are properly corrected.

Who decides which level of inspection to perform?

Both the Commercial Vehicle Safety Alliance (CVSA) and the Federal Motor Carrier Safety Administration have a part in DOT inspection levels. The CVSA develops the criteria and sets the procedures for every inspection level. The FMCSA establishes overall regulations and determines which vehicles must be inspected.

How often do DOT inspections happen?

DOT inspections can happen at any time. They most commonly happen during roadside stops and weigh stations. Carriers with higher risk, poor safety records, or hazardous material may be inspected more frequently.

What documents are required during an inspection?

Documents required during an inspection include but may not be limited to:

  • State driver’s license or commercial driver’s license
  • Medical examiner’s certificate
  • Record of duty status
  • Vehicle registrations
  • Periodic inspections document for all vehicles being operated
  • Shipping papers or bills of lading
  • Information for hazardous materials being transported
  • Proof of insurance

What are common DOT inspection violations?

According to the FMCSA, the 5 most cited roadside violations are:

  1. False Report of Driver’s Record of Duty Status: log falsification providing inaccurate or intentionally altered duty-status information.
  2. No Record of Duty Status (ELD Required): using a commercial vehicle without the required electronic logging device or valid time records.
  3. Inoperable Required Lamp: crucial lights (headlights, brake lights, turn signals, etc.) are not functioning properly.
  4. Operating a Commercial Motor Vehicle Without a Commercial Driver’s License (CDL)
  5. Operating a Commercial Motor Vehicle Without Proof of a Periodic Inspection: failure to meet FMCSA the maintenance standards of a required annual inspection.

Why is updating VMT important for compliance?

VMT is tracked to determine fuel tax obligations (Vehicle Miles Traveled Tax) used for road maintenance and improvements. Trucking companies must keep accurate records of VMT to ensure they pay the correct amount of taxes.

How often should VMT be updated?

For motor carriers VMT must be updated every two years along with the MCS-150 form for the Biennial Update.

Can VMT be tracked automatically with technology?

Yes, Electronic Legging Devices (ELDs), Fleet Management Apps, and Mileage Tracking Software are all technological advancements that can simplify the process of VMT tracking.

How does VMT affect taxes and fuel reporting?

Accurate VMT records help document mileage for business-related tax deductions, ensuring compliance with IRS regulations. It also supports fuel tax reporting by tracking the miles each vehicle travels in different jurisdictions, which is essential for state and federal fuel tax calculations. Proper tracking reduces errors, prevents penalties, and provides a clear record of operational costs.

How do I know when my Biennial Update is due?

  • Your filing schedule depends on the last two digits of your USDOT number. The last digit corresponds with what month the form needs to be filed in. January is 1, February is 2, March is 3, etc. The next to last digit determines the year (odd-numbered year or even numbered year). For example, DOT number 1234567 files their biennial update in July (7) of every even year (6). Contact us today to see if you’re due.

Does the Biennial Update cost money to file?

While you can file your Biennial Update yourself for no cost through FMCSA. The process can often be confusing and time-consuming. Our team can handle your filing for you, simplifying the process for you.

Do intrastate carriers need to file the update?

Yes, even if carriers stay within state lines, a biennial update is still needed for their USDOT number.

What happens if I miss my filing deadline?

  • Failure to complete biennial update to FMCSA can be subject to fines with a maximum penalty of $10,000. If your update is past due, you can still file it to restore your compliance status. Contact us today to file your form! https://dotcompliancegroup.com/bu-update/ 

What are the new FMCSA rules in 2025?

  1. Civil Penalty Amount Increases
  2. Drug & Alcohol Clearinghouse Becomes Exclusive Source for checking driver history.
  3. ELD Technology Required
  4. SMS (Safety Measurement System) Modernization
  5. Crash Preventability Determination Program Expanded

When do the 2025 FMCSA regulations take effect?

The confirmed dates these regulations take effect is May 30, June 23, October 1, 2025.

How can trucking companies prepare for these changes?

Regularly reviewing your Safety Measurement System (SMS) scores and maintaining personal checklists for inspections, driver qualification files, and drug and alcohol testing helps catch issues before they affect audits. Partnering with DOT Compliance Group streamlines filings, reporting, and ongoing monitoring, taking the guesswork out of FMCSA regulations and keeping your operation audit-ready year-round.

What Triggers a DOT Compliance Review?

A DOT compliance review is triggered when FMCSA wants to ensure a carrier is following safety regulations. Common triggers include high SMS safety scores, a history of crashes or violations, and previous noncompliance. Staying proactive with accurate records, driver files, and regular internal audits helps reduce the likelihood of a review.

Where can I get help with FMCSA filings?

DOT Compliance Group can assist with any help or questions you may have about FMCSA filings. Call 972-476-9962.

How long are violations kept on record?

According to the Clearinghouse rules, drug and alcohol violations remain in the FMCSA Clearinghouse for five years, provided all requirements (such as completing the return‑to‑duty process) have been met before that period ends.

What if an employer makes a mistake in reporting?

In practice, correcting an employer reporting error typically involves identifying the mistake in the database and then submitting a request for correction through the Clearinghouse portal or FMCSA procedures, so the record reflects accurate information. 

What are the penalties for non-compliance?

FMCSA rules allow civil penalties for non‑compliance, and separate authorities note that employers who fail to meet Clearinghouse requirements may face civil fines or criminal penalties under federal regulations.

Do trucking companies check the Clearinghouse?

Yes — trucking companies check the Clearinghouse as part of their hiring and compliance process. The FMCSA Clearinghouse is designed so employers can search a driver’s drug and alcohol violation records before permitting them to operate a commercial vehicle. Employers are required to conduct these queries for both prospective and current drivers as part of compliance.
