Using SIC & NAICS Data in CRM & Lead Scoring Models

Adding verified SIC and NAICS codes to your CRM unlocks precise segmentation, more reliable lead scoring, and better campaign performance. Standardized industry fields make it easier to match offers to the right markets, benchmark performance, and automate journeys with confidence.

Why industry codes improve lead scoring

Fit scoring: Prioritize industries with the highest conversion or LTV based on historical wins.
Routing accuracy: Assign the right SDR/AE by industry vertical or territory policy.
Personalization: Trigger industry-specific emails, ads, and sales plays from standardized fields.
Attribution clarity: Report performance by verified cohorts instead of inconsistent free-text labels.

Core fields to maintain in your CRM

SIC_Code (4-digit) and/or NAICS_Code (6-digit)
Code_Version (e.g., NAICS 2022) and Verified_Date
Industry_Label (standard description mapped from the code)
Source and Confidence (optional, for governance)

Look up and confirm valid codes using the SIC Code Lookup / Directory and the NAICS Code Lookup / Directory.

How to integrate codes into CRM workflows

Append verified codes to accounts, leads, and contacts. See What Is a SIC Code Append for how standardized appending works.
Normalize picklists so users select from valid codes/labels—no free typing.
Update automations (flows/journeys) to branch by industry cohort.
Report by cohort (code × region × company size) for conversion and pipeline analytics.
Re-verify periodically to catch M&A or business model changes. Learn the flow in How It Works.

Example: simple lead score by industry fit

Rule	Criteria	Score
High-fit industries	NAICS in target list	+25
Mid-fit industries	NAICS adjacent to target	+10
Exclude segments	NAICS on blocklist	-50

Target lists can be sourced from your ideal customer profile and validated using the Business List By NAICS Code.

Best practices for data hygiene

Append on intake: Enrich new records immediately to prevent routing delays.
Lock values: Use picklists mapped to official code tables to avoid typos.
Log lineage: Keep source, version, and verified date for auditability.
Quarterly re-check: Schedule re-append and drift checks for key accounts.
