How to find company DUNS number
Describe your target industry or market
Paste your target industry or market into the prompt field. Sculptor builds a filtered company list and then appends the DUNS number for each match.
Sculptor sources companies and fetches DUNS data
Sculptor assembles a company list filtered by your target industry from Clay's company database, then runs each row through Clay's provider network to retrieve the nine-digit DUNS number tied to that business. Only rows with a confirmed match return a DUNS value.
Get company name and DUNS number per row
The finished table shows company name and DUNS number for matched rows. Export to CSV, sync to Salesforce, or pipe into your compliance or outbound tool of choice.
Why Clay for finding company DUNS numbers
Source companies by industry in one table
Filter Clay's B2B company database by industry, headcount, funding stage, location, and tech stack to build your target list. Every matched row is ready for DUNS enrichment in the same workflow.
Pull DUNS numbers via native Aviato enrichment
Run the "Find private company legal compliance data" action to retrieve the nine-digit DUNS number, CAGE code, and NAICS industry code for each matched company. Credits only charge on a confirmed match.
Claygent fills gaps with web research
When a structured lookup returns no match, Claygent browses each company's site and public registries to surface DUNS data that isn't in traditional databases. No manual research required.
Auto-refresh and sync enriched records to CRM
Schedule regular enrichment runs to keep DUNS data current as your list grows, then push updated records directly to Salesforce or HubSpot without a manual export.
Clay is a game changer for marketing, data, and operations. We have 3x our enrichment rate with Clay’s combination of data providers. Clay makes it easy to use AI for GTM initiatives, unlocking new workflows that were infeasible before.
Frequently asked questions
How does Sculptor find company DUNS numbers?
Sculptor takes your industry filters or company list, searches its database of billions of company profiles, and runs the "Find private company legal compliance data" action on each match. That action returns the nine-digit DUNS number alongside the CAGE code and NAICS classification in a single enrichment step, so every row populates without a separate lookup.
How accurate are the DUNS number results?
Dun & Bradstreet's global database contains over 300 million business records, so coverage skews high for established companies. Clay's enrichment action includes a "Require DUNS number" toggle that only charges credits when a DUNS is found, meaning you skip blanks and pay only for confirmed hits. Coverage will be lower for very small or newly formed entities that haven't yet registered with D&B.
Can I look up DUNS numbers for a whole list at once?
Yes. Paste a list of company names or domains directly into your Clay table, upload a CSV, or pipe records from an existing table. Sculptor runs the legal compliance data action on every row in parallel, so you can enrich hundreds or thousands of companies in one pass. Export the finished table to HubSpot, Salesforce, or a CSV for vendor onboarding or procurement workflows.
Is it legal to collect and use company DUNS numbers?
DUNS numbers are company-level identifiers, not personal data, so they fall outside most individual privacy regulations like GDPR and CCPA. Under GDPR, company firmographic data (legal name, DUNS, CAGE code) is generally not considered personal data. In the US, no federal law restricts the use of publicly assignable business identifiers for procurement or vendor qualification purposes.
That said, Dun & Bradstreet's own terms govern how its data may be redistributed. Always check the rules for your jurisdiction and respect data provider terms of service before sharing enriched records externally.
