Verified SIC and NAICS classifications are foundational for analytics, AI modeling, market intelligence, and regulatory compliance. This page presents evidence for accuracy, stability, and auditability—so teams can reduce drift, improve cohort integrity, and support reproducible analysis in decision-critical environments.

Why Accuracy Matters for Analytics, AI & Compliance

Inaccurate industry classification creates downstream errors in market analysis, segmentation, forecasting, AML/KYC modeling, and regulatory reporting. Organizations relying on self-reported or keyword-derived codes often experience noisy cohorts, misaligned peer groups, unstable dashboards, and increased compliance risk.

Financial impact: Misclassification reduces targeting precision and can skew market sizing and KPIs because one incorrect label propagates into cohorts, rollups, and models.

Two Practical Risk Models (Plug In Your Numbers)
Marketing waste model Estimate wasted spend caused by misclassified targeting.
Wasted Spend ≈ Total Spend × Misclassification Rate × (1 − Match Quality)
Compliance review load model Estimate extra reviews created by misclassified entities.
Extra Reviews ≈ Total Onboardings × Misclassification Rate

Verified codes reduce these risks by providing stable, evidence-backed, audit-ready industry labels. For process details, see Our Verification Methodology.

SICCODE.com vs Generic Providers

Generic Process (Typical)
  • Scraping or directory category ingestion
  • Keyword match → coarse mapping
  • Opaque confidence (limited explanation)
  • Unversioned updates → drift over time
SICCODE.com Process (Verified)
  • Multiple sources + normalization
  • ML-assisted candidate ranking
  • Human review/verification for high-impact cases
  • Rationale metadata + versioned releases

Definition: “Generic providers” refers to typical directory-based datasets, scraped-code feeds, and low-cost API sources that often conflate categories with official SIC/NAICS standards and do not provide governed verification, rationale metadata, or versioned change logs.

Data Quality Benchmark Table

Metric SICCODE.com Generic Provider (Typical) Key Advantage
Accuracy rate (validated) 96.8% (verified) 1 Varies; often unpublished or estimated Reduces false positives/negatives in targeting, risk tiering, and cohort analysis
Cohort stability (time-series drift) Low (versioned rollups + deltas) 2 Medium–High (untracked changes) Maintains longitudinal integrity for forecasting and ML training sets
Auditability Rationale metadata + change logs 3 Minimal/none Supports internal/external audits and reproducible analytics
Classification evidence inputs Multi-source + governed definitions 4 Often limited to directory/site content Improves correctness for complex or hybrid businesses
Update transparency Rolling updates with deltas Irregular; no delta reporting Explains changes over time and reduces analytical breakage

Benchmarking Methodology

Comparison Process (High-Level)
1) Establish ground truth Use governed SIC/NAICS definitions and reviewed evidence to define primary activity for sampled entities.
2) Run challenge testing Compare SICCODE.com assignments versus generic outputs (when available) using consistent evaluation rules.
3) Measure outcomes Compute accuracy, drift/stability, auditability coverage, and update transparency.
Metric Definitions (How to Interpret This Page)
  • [1] Accuracy: agreement of primary industry assignment with a reviewed “ground truth” set defined by governed SIC/NAICS rules and expert adjudication.
  • [2] Drift/Stability: how much cohort membership changes over time due to unversioned updates or inconsistent rollups; low drift supports longitudinal analysis.
  • [3] Auditability: availability of rationale metadata, versioning/timestamps, and change logs to reproduce and explain assignments.
  • [4] Sources: breadth of evidence inputs used to support correct primary activity determination under official definitions.
  1. Governed definitions: Official SIC/NAICS definitions applied as structured interpretation rules. See Verification Methodology.
  2. Evidence normalization: Inputs are normalized and resolved to reduce duplication and improve comparability.
  3. ML + human review: Models propose candidates; senior analysts adjudicate edge cases. See About Our Data Team.
  4. Versioning: Updates are managed with change tracking to reduce drift and support reproducible rollups.

Common Generic Database Issues

  • Keyword over-reliance: marketing language mapped to industries that don’t reflect primary activity.
  • Primary-activity confusion: secondary offerings override true principal activity.
  • Duplicate entities: HQ/branch duplication distorts counts, cohorts, and risk models.
  • Unstable rollups: unversioned updates break time-series continuity.
  • Framework misalignment: mixing SIC/NAICS rules or using outdated versions can skew reporting.
