Primary vs Secondary Classification

This is a Primary Classification

Class code 7231 is a primary classification, meaning it directly describes the main business operations of an employer. Primary codes represent the core activity — what the business actually does.

A secondary (or standard exception) code describes support operations that exist in almost every business, like clerical work (8810) or outside sales (8742). These are assigned in addition to the primary code.

If your business primarily involves courier or messenger service companies and mail, parcel or package deliveryùall employees & drivers, this code should be your governing classification — the one that applies to most of your payroll.

How Class Code 7231 Affects Your Premium

Your workers’ compensation premium for employees classified under code 7231 is calculated as:

Premium = (Payroll / 100) × Rate × EMR

Where the rate is determined by your state and carrier, and EMR (Experience Modification Rate) reflects your company’s claims history relative to similar businesses. A lower EMR means lower premiums.

Accurate classification is critical — misclassifying employees under the wrong code can result in overpayment or underpayment that gets corrected during an audit.
