Data Lifecycle Management & Version Control
SICCODE.com governs SIC and NAICS classification data as a living system, not a static lookup. This page documents how codes and classification records move through a formal lifecycle—initial assignment, maintenance, version control, and archival—so users can rely on current standards alignment while preserving historical context for audit, analytics, and regulatory use.

Why lifecycle governance matters
Industry classification changes as the economy changes. Definitions evolve, standards are revised, and organizations shift products, services, and operating models over time. A governance-grade dataset must therefore document how data changes, why it changes, and which standard it is aligned to.
Governance principle: SICCODE.com manages classification data through repeatable lifecycle rules so every code assignment remains explainable, comparable across time, and suitable for high-stakes use cases (risk, compliance, underwriting, analytics, and reporting).
Lifecycle stages we govern
1) Initial Assignment (Creation)
A business record is assigned a primary SIC/NAICS classification based on authoritative definitions and governed interpretation rules. Primary activity is identified and documented, while secondary activities can be recorded when they materially affect classification understanding.
- Primary activity determination
- Secondary activity capture (when relevant)
- Edge-case flagging for expert review
2) Maintenance (Ongoing Accuracy)
Classifications are reviewed and maintained as businesses and standards evolve. Maintenance includes validation workflows, anomaly detection, and expert review when changes are detected or reported.
- Signal-based review triggers
- Quality thresholds and exceptions
- Review Team adjudication
3) Versioning (Controlled Change)
When a classification decision is updated, SICCODE.com records version-relevant context so users can interpret changes without losing historical continuity.
- Effective date context
- Reason for update
- Standards reference (where applicable)
4) Archival & Deprecation (Historical Integrity)
Outdated or legacy classifications can be preserved for longitudinal research and compliance contexts, while deprecated codes and stale mappings are clearly identified to prevent misuse.
- Legacy code preservation
- Deprecation labeling
- Historical mapping support
Version control & standards alignment
SICCODE.com aligns classifications to modern standards while documenting what standard a user should interpret the record against. As a default governance rule:
Standards rule: All NAICS classifications are mapped to the latest supported NAICS standard (e.g., NAICS 2022) unless otherwise stated. When historical context is needed, legacy mappings may be provided with clear labeling.
Note: Some use cases require historical comparability; others require current regulatory alignment. Lifecycle governance supports both.
Change triggers & review thresholds
Lifecycle management depends on defined triggers so the dataset remains current without introducing unnecessary churn. Common triggers include:
- Business activity changes: product/service shifts, mergers, new lines of business
- Data anomaly detection: conflicts between attributes and claimed industry
- Standards updates: changes to NAICS definitions and rollups
- User-submitted corrections: reviewed under governed escalation
Archival, deprecation, & historical mappings
Governance requires that outdated classifications do not silently persist in the “current” dataset. When a code or mapping is no longer appropriate, SICCODE.com applies one of the following actions:
- Archival: preserved for historical analysis with clear labeling
- Deprecation: marked as outdated to prevent modern use in compliance contexts
- Removal: records that no longer meet quality standards may be removed from active datasets
Audit-ready outputs
Lifecycle governance is designed to support audit and explainability requirements. Depending on product context, SICCODE.com aims to provide:
- Clear “current standard” interpretation guidance
- Documented change reasoning (where applicable)
- Traceable review paths through governed processes

FAQ
- How often are classifications updated?
Updates occur through governed maintenance workflows triggered by standards changes, anomaly detection, and expert review processes. - Do you preserve historical classifications?
Yes. Where needed for longitudinal analysis and compliance contexts, legacy mappings may be preserved with clear archival labeling. - Which NAICS version do you align to?
As a governance rule, NAICS classifications are mapped to the latest supported standard (e.g., NAICS 2022) unless otherwise stated.
