What is SICCODE.com
A classification-focused platform for reference, interpretation, and application
SICCODE.com began as an online industry classification and business information resource and expanded over time to support both SIC and NAICS. Today, the platform combines public reference content with services designed for users who need more than a simple code lookup.
That includes code detail pages, lookup directories, conversion tools, governance and methodology pages, business list services, code appending, enrichment, and CodeMatch support for businesses that need help identifying the right code.
Independence and scope statement: SICCODE.com is an independent reference and services platform. It is not a government agency and does not issue official government determinations. Paid services do not redefine official standards or alter published governance practices.
Company background
Built over time around classification expertise
SICCODE.com was founded in 1998 at a time when organized SIC reference material was far less accessible online. As NAICS became the primary modern classification framework, the platform expanded to support both systems and the relationship between them.
That expansion included lookup directories, code detail pages, conversion tools, and related reference content designed to help users understand definitions, boundaries, and code relationships. Over time, the platform also developed applied services for organizations that needed classification support tied to business data and operational use cases.

Governance and review
Trust is supported by documented standards

Instead of relying on broad marketing language, it points users to the pages that explain how classification content is framed, how review standards are presented, and how more ambiguous or higher-stakes cases are handled.
