NAICS Code Appending – Match NAICS Codes to Your Company Database
SICCODE.com’s NAICS Code Appending service matches verified NAICS classifications to the companies in your existing database. This is designed for organizations that need accurate, defensible industry coding to improve segmentation, targeting, analytics, and downstream marketing decisions.
Classification-first matching
NAICS codes are applied using governed classification logic—built for consistent targeting, analysis, and explainability.
Works with your existing data
Append NAICS codes directly to your CRM, marketing database, analytics warehouse, or internal customer file.
Scope-aware processing
Matching is tailored to your file structure and objectives so results are usable for segmentation—not generic labeling.
Validation + final quality review
Matched results pass validation checks and a final review to confirm alignment and reduce classification noise.
Why Append NAICS Codes to Your Database
Without standardized industry classification, companies are difficult to segment consistently across teams and time. NAICS code appending helps you:
- Identify ideal target companies based on verified industry activity.
- Understand which industries perform best across your existing customers.
- Align marketing, sales, and analytics around a shared industry framework.
- Reduce noise caused by inconsistent or self-reported industry labels.
Official & Extended NAICS Codes
SICCODE.com uses NAICS in two complementary ways—so you can balance standards alignment with practical segmentation:
- Official NAICS (2–6 digit): The U.S. Census standard used for reporting, benchmarking, and consistent industry grouping.
- Extended NAICS (8-digit marketing segments): Additional granularity designed for targeting, analytics, and niche market identification—useful when 6-digit groupings are too broad for campaign relevance.
Note: “Extended” NAICS segments are not an official government NAICS level; they are an enhanced segmentation layer used for marketing and analysis.
How NAICS Code Appending Works
- 1) Secure file submission: You provide your business data file under confidentiality.
- 2) Classification matching: Records are matched and assigned NAICS codes using SICCODE.com’s governed framework.
- 3) Validation + delivery: Results are validated and reviewed before being returned for targeting, analysis, or modeling.
Example: Using NAICS Matching to Expand Market Reach
A supplier submits its internal customer database for NAICS code appending. After matching, analysis shows that the highest-value customers cluster within a small set of NAICS categories.
With industry scope clarified, the organization can refine outreach by geography, size, and role criteria—reducing wasted outreach and improving list relevancy.
