Data Accuracy Benchmarks: SICCODE vs Generic Providers
SICCODE.com vs Generic Providers
On this page
Verified SIC and NAICS classifications are foundational for analytics, AI modeling, market intelligence, and regulatory compliance.
This page presents the evidence behind SICCODE.com’s superior accuracy, stability, and auditability—showing how verified classification
outperforms generic, unverified data sources 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 (missed segments, wasted impressions, inefficient territory planning) and can skew market sizing and performance KPIs because one incorrect label propagates into cohorts, rollups, and models.
Compliance & risk: In regulated workflows, incorrect SIC/NAICS can affect KYC/AML onboarding, OFAC/sanctions screening, ESG rollups, and sector-based reporting where internal audit teams expect documented rationale and stable, reproducible assignments.
Verified codes reduce these risks by providing stable, evidence-backed, regulator-ready industry labels. Learn how verified classification works in Our Verification Methodology.
SICCODE.com vs Generic Providers
- Scraping or directory category ingestion
- Keyword match → coarse mapping
- Low confidence output (often opaque)
- Unversioned updates → drift over time
- Multiple data sources + normalization
- ML-assisted candidate ranking
- Human review/verification of edge cases
- Rationale metadata + versioned releases
- SICCODE.com: Dual-source validation, ML-assisted predictions, human-reviewed assignments, rationale metadata, lineage logs, and version-controlled updates.
- Generic Providers: Self-reported or scraped keywords, inconsistent rollups, limited review, and no visibility into how or when a code was assigned.
Definition: “Generic providers” refers to typical directory-based datasets, scraped-code feeds, and low-cost API sources that often conflate directory 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 (Average) | Key Advantage |
|---|---|---|---|
| Accuracy rate (validated) | 96.8% (verified) 1 | Varies; often estimated in unverified datasets | 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 sources | Multi-source (official + proprietary signals) 4 | Often 1–2 (directory/site content) | Improves completeness and confidence for complex businesses |
| Update cadence | Rolling updates with deltas | Irregular; no delta reporting | Reduces drift and explains changes over time |

“Generic” = typical scraped or directory-based providers without formal verification. Where generic accuracy is referenced, it is commonly an estimate because many providers do not publish validation methodology, audit trails, or challenge-testing results.
SICCODE.com Benchmarks & Impact
- 250,000+ organizations supported
- 300,000+ analytics and marketing implementations analyzed
- Full U.S. coverage with extended 6-digit depth and adjacency intelligence
- Credit risk: If 1-in-5 entities are misclassified in an unverified dataset, risk tiering and peer-group comparisons can be materially distorted—leading to incorrect policy or underwriting assumptions.
- AI/ML: High cohort stability helps prevent training-set drift, improving reproducibility and reducing unexpected performance degradation over time.
Benchmarks reflect validated performance across workflows from 2015–2025. See comparative analysis at Data Accuracy Benchmarks.
How Our Benchmarking Methodology Works
Benchmarking uses multi-industry sampling and challenge testing. Sample composition and size can vary by audit cycle; what remains
consistent is the use of governed SIC/NAICS definitions, normalized evidence, and expert adjudication of ambiguous cases.
- [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: the degree to which cohort membership changes over time due to non-versioned updates or inconsistent rollups; low drift supports longitudinal analysis.
- [3] Auditability: availability of rationale metadata, timestamps/versioning, and change logs to reproduce and explain assignments.
- [4] Sources: breadth of evidence inputs (official definitions plus normalized business activity signals) used to support correct primary activity determination.
- Regulatory-driven definitions: Official SIC/NAICS rules encoded as structured eligibility logic. Details at Our Verification Methodology.
- Feature extraction: Text, entity, network, and geospatial features harvested from normalized sources.
- ML + human review: Models propose candidates; senior analysts adjudicate edge cases. Meet the team at About Our Data Team.
- Versioning & auditability: Each assignment contains timestamped rationale, reviewer metadata, and delta logs. Framework explained in Governance Standards.
Common Issues in Generic Databases
- Keyword over-reliance: Content and marketing language mapped to industries that don’t reflect the primary business activity.
- Primary-activity confusion: Secondary products/services override true principal activity.
- HQ/branch duplication: Duplicate entities inflate counts and distort targeting and risk models.
- Unstable rollups: Non-versioned updates break time-series continuity.
- SIC/NAICS misalignment: Confusing frameworks or using outdated versions can distort reporting.
