Quick Answer

A SCAC code, or Standard Carrier Alpha Code, is a unique two to four letter code that identifies a transportation company. It is assigned by the National Motor Freight Traffic Association and used on bills of lading, in electronic data interchange, and by shippers, retailers, railroads, and government agencies. Carriers apply for one and renew it for an annual fee.

If you have moved freight for a large retailer, the government, or an intermodal shipper, someone has probably asked you for your SCAC code. It looks like a random string of letters, but it is a real identifier with a specific job. Here is what it is and how to get one.

What is a SCAC code?

SCAC stands for Standard Carrier Alpha Code. It is a unique code of two to four letters that identifies a transportation company on shipping paperwork and in electronic systems. Think of it as a short, standardized name tag for your carrier so that computers and trading partners can recognize you consistently. The code is assigned and maintained by the National Motor Freight Traffic Association.

Who needs a SCAC code?

Not every carrier needs one, but many larger operations do. A SCAC is commonly required to do business with big retailers, the United States military and other government shippers, railroads and intermodal partners, and anyone exchanging shipment data electronically. If your customers use electronic data interchange or file customs and manifest documents, they will usually ask for your SCAC.

How do you get a SCAC code?

You apply through the National Motor Freight Traffic Association, which is the body that issues and controls the codes. You submit your company details, and once approved you are assigned your unique code. Because the association manages the whole system, you cannot simply make up your own code, and you renew it to keep it active.

How much does a SCAC code cost and how long is it valid?

A SCAC is not a one time purchase. The National Motor Freight Traffic Association charges an application fee and an annual renewal fee, with the exact amounts set by the association, so you keep the code active by renewing it each year. Always check the current fee and renewal terms directly with the association before you apply.
