Data Sources & Verification Process

SICCODE.com delivers governed industry classification by integrating verified datasets spanning federal, state, commercial, and proprietary registries. This scale—combined with a disciplined verification pipeline and documented review pathways—supports consistent, defensible SIC and NAICS assignments for decision-critical analytics, compliance, and AI systems.

Behind each record is a multi-stage pipeline that aggregates, normalizes, and validates entity signals using authoritative public sources, audited commercial data, and governed extensions. Updates are managed using versioned practices to preserve longitudinal comparability. For end-to-end workflow details, see our Verification Methodology.

Primary Data Sources

• U.S. federal data: filings, datasets, and registries used as baseline reference inputs and integrity anchors.
• State-level registrations: incorporation and licensing feeds used to improve entity coverage and recency signals.
• Commercial data partners: audited vendor datasets used to enrich firmographics and operating indicators.
• Proprietary contributions: governed mappings for emerging and hybrid industries, including SIC 6-Digit Codes.

Normalization & Data Integration

Incoming inputs are standardized into a unified schema. Entity names, addresses, and activity descriptions are normalized using controlled vocabularies and entity-resolution techniques. Each record receives a persistent identifier to preserve lineage from source intake through verification and controlled updates.

Verification Framework

1. Rule-based validation: inclusion/exclusion logic enforces alignment with official SIC and NAICS structures.
2. Machine-assisted scoring: models and heuristics rank candidate codes using evidence signals and confidence patterns.
3. Review pathways: analysts adjudicate edge cases and document rationale under Editorial & Neutrality Standards.
4. Version control: updates are recorded with change context (and where applicable) reviewer attribution for audit tracking.

Continuous Quality Assurance

• Quality audits benchmark accuracy, coverage, and stability using internal QA and exception review.
• Rolling updates incorporate new formations and operational changes while preserving traceability.
• Versioned change logs support controlled adoption in BI, CRM, and regulated workflows.

Verification Metrics

• Classification accuracy: 96.8% (validated benchmark)
• Retention accuracy: 99.3% for established entities
• Initial confidence for new records: 92%+ prior to exception review

Metrics reflect internal audits conducted under SICCODE.com’s verification and QA cycle. For benchmarking comparisons, see Data Accuracy Benchmarks: SICCODE vs Generic Providers.

Audit-Ready Evidence Outputs

For procurement, model governance, and regulated programs, verified datasets may be accompanied by audit-oriented documentation depending on product context and licensing scope. Typical evidence outputs include:

• Record-level lineage attributes (source category, timestamps, update context)
• Change logs or change files for comparability across releases
• Governance documentation describing verification rules and escalation pathways
• Standards alignment guidance for interpreting SIC/NAICS assignments

Applications in Analytics, AI & Compliance

Verified classification data supports CRM enrichment, segmentation, underwriting analytics, compliance validation, and ML training datasets. With documented lineage and governed update practices, SICCODE.com supports transparent, explainable, and audit-ready pipelines.
