Frequently Asked Questions

What is NAICS 8139? ▾
NAICS 8139 classifies business, professional, labor, political, and similar organizations that operate primarily to advance the interests of their members or constituencies. This includes trade associations, professional societies, labor unions, business leagues, political parties and committees, and advocacy organizations. These entities typically operate on membership dues or contributions rather than selling products or services to the general public.
How do organizations in this industry generate revenue? ▾
Primary revenue sources include membership dues, which form the financial foundation for most organizations, along with conference and event registration fees, publication sales, training and certification programs, and donated contributions. Many organizations also generate revenue through sponsorships, advertising in member publications, and ancillary services provided to their membership base. Political organizations rely heavily on campaign contributions and fundraising activities.
What is the difference between a trade association and a professional society? ▾
Trade associations typically represent businesses within a specific industry and focus on industry-wide issues, regulatory advocacy, and competitive concerns. Professional societies, by contrast, represent individual practitioners within a profession and emphasize credentialing, continuing education, ethical standards, and professional development. Both are membership organizations but differ in their constituent bases and primary missions.
How do labor unions fit into this industry classification? ▾
Labor unions are classified under NAICS 8139 as organizations representing workers' collective interests regarding wages, benefits, working conditions, and workplace rights. Unions engage in collective bargaining, contract negotiation, advocacy for labor legislation, and member services including training and grievance representation. They operate as membership-based organizations supported primarily through member dues.
What regulatory requirements govern these organizations? ▾
Organizations in this sector face varying regulatory requirements depending on their type and activities. Political organizations must comply with Federal Election Commission reporting requirements and campaign finance regulations. Labor unions are subject to Department of Labor oversight and collective bargaining regulations. Tax-exempt organizations must maintain nonprofit status compliance, and lobbying organizations must register and report under the Lobbying Disclosure Act if their activities meet threshold requirements.
