Bulk Classification Overlay & Integration | Apply SIC/NAICS to Internal Records
Updated: 2026 Reviewed By: SICCODE.com Industry Classification Review Team Category: Applied Data Services & Use Cases
Enterprise Service: Apply SIC/NAICS classifications to your internal locations, accounts, and IDs (batch overlay or integration workflow).
Bulk Classification Overlay & Integration Services help organizations apply a consistent SIC/NAICS industry layer to internal records.
This is commonly used for portfolio segmentation, risk and compliance workflows, territory planning,
data enrichment, and platform features.
Organizations request overlays when they already have location or account records but need standardized SIC/NAICS codes to power analytics and decisioning.

What you provide (inputs)
Overlays are easiest when input data is consistent and includes stable keys.
Primary key: your internal ID (location_id, account_id, org_id, etc.).
Entity name: business/location name (optional but helpful).
Address fields: street, city, state, ZIP (or lat/long if that’s your standard).
Existing codes (optional): any current NAICS/SIC fields for comparison and conflict review.
Scope notes: what the overlay will be used for (risk, mapping, platform feature, etc.).
If your records include multiple locations per entity, we can structure the overlay at the location level (recommended for mapping use cases).
What you receive (outputs)

Dashboards can toggle between broad and detailed views
Crosswalk fields (optional)
Bridge NAICS ↔ SIC when both are needed
Supports legacy reporting and migrations
Confidence tier (optional)
Tier label or review depth indicator
Helps governance, audit workflows, and exception handling
Documentation package
Data dictionary + scope notes + version label
Governance-friendly deployment and repeatability
Typical overlay workflow
This process is designed for enterprise teams that need repeatable joins and consistent results across refresh cycles.
Step 1
Intake & scoping
Define unit of analysis (location vs account), required code depth, target geographies, and how the overlay will be used.
Step 2
Schema alignment
Confirm field names, formats, keys, and output structure so your team can join it with one line of SQL.
Step 3
Overlay delivery
Receive the join-ready overlay file with NAICS/SIC fields, rollups, and documentation.
Step 4
QA & reconciliation
Validate counts, spot-check segments, compare against existing codes, and flag exceptions for review if needed.
Step 5
Refresh (optional)
Set refresh cadence and change notes so your systems remain consistent over time.
Overlays can be aligned to establishment-level activity when location records represent distinct operating units.
The exact matching approach depends on your inputs (addresses, IDs, existing codes) and your governance requirements.
Location-first: best for GIS, site selection, and multi-location segmentation.
Account-first: best for CRM reporting when locations are not distinct.
Crosswalk support: bridge SIC ↔ NAICS for legacy continuity.
QA & confidence tiers (optional)
Enterprise teams often need a way to label confidence and route ambiguous cases for review.
Confidence tier field (optional): a simple label to support downstream logic.
Exception handling: flag records with incomplete inputs or conflicting signals.
Audit-friendly documentation: scope notes and definitions support internal reviewers.
Portfolio segmentation: classify internal locations to quantify exposure by industry.
Territory planning: overlay industries to align regions with target density.
Compliance reporting: standardize industry buckets across business units and subsidiaries.
Customer-facing features: enable filters, categories, and insights in SaaS products.
Data harmonization: bridge SIC/NAICS reporting across merged datasets or acquisitions.
FAQ
Do we need addresses for every record?
Addresses (or lat/long) are strongly recommended for location-level overlays. If your use case is account-level reporting, we can scope an account-first approach depending on your data model.
Can you deliver the overlay keyed to our internal IDs?
Yes. That is the standard enterprise delivery: a join-ready overlay file keyed to your internal IDs.
Do you include rollups (NAICS 2–6)?
Yes, rollup fields are commonly included so dashboards can switch between broad and detailed views.
Can we add a confidence tier field?
Yes. Many teams request a tier label to support governance workflows and exception handling.
Is this the same as dataset licensing?
Licensing governs permitted usage. Overlay services focus on applying SIC/NAICS to your internal records. See
NAICS & SIC Dataset Licensing
for licensing context.
Is this intended for marketing outreach lists?
This service is designed for internal records and enterprise workflows. If you need marketing lists, see
Business Lists.
