Standard Occupational Classification (SOC) is a statistical standard that federal agencies use to classify workers into job-related categories. The ultimate purpose of which is to collect, calculate and disseminate data. The Bureau of Labor and Statistics uses SOC codes in its Occupational Employment Statistics (OES) Survey, which can be helpful to employers when they set their pay scales. In some states, SOC codes are also an essential part of unemployment reporting compliance.

How to read a standard occupational classification (SOC) code

SOC codes have six digits with a hyphen inserted between the second and third digits for clarity. They can be decoded as follows:

  • First two digits = major group
    Major groups always end in 000.
  • Third digit = minor group
    Minor groups usually end in 000, though a few occupations end in 00.
  • Fourth and fifth digits = broad occupation
    Broad occupations always end in 0.
  • Sixth digit = detailed occupation
    Detailed occupations always end in a number other than 0.

Example:

33-0000 Protective Service Occupations (major group)
33-1000 Supervisors of Protective Service Workers (minor group)
33-1010 First-Line Supervisors of Law Enforcement Workers (broad occupation)
33-1011 First-Line Supervisors of Correctional Officers (detailed occupation)

Detailed SOC occupations

There are as many as eight elements to a detailed occupation classification:

  1. SOC code
  2. Title
  3. Definition
  4. Statement of required duties
  5. “May” statement
  6. “Includes” statement
  7. “Excludes” statement
  8. Illustrative examples

Duties that workers might have to perform, but are not necessarily required, fall under “may” statements. The “includes” statement lists certain workers who should be classified under the SOC code. Similar occupations that have their own SOC code are noted in the “excludes” statement.

Which states require SOC codes?

Some states require employers to provide SOC codes in their quarterly unemployment insurance reports. These states include:

  • Alaska
  • Louisiana
  • Washington
  • South Carolina (effective March 2024)
  • West Virginia (effective January 2024)

Employers should review their state’s unemployment requirements for more specific information.

What are SOC codes used for?

SOC codes make it possible for public and private organizations to comparatively analyze occupations in the United States. For instance, state agencies often use SOC codes to identify different types of workers and industries in their respective jurisdiction. They’re also helpful to employers who rely on BLS data to determine compensation ranges across various positions in their industry.
