Why Clay for finding company SIC codes
Multi-provider waterfall for SIC coverage
Get SIC codes for matched rows across your account list. Clay waterfalls through multiple providers in sequence and only charges credits when one returns a confirmed industry classification code.
Claygent fills gaps providers miss
When structured databases return nothing, Claygent browses each company's site and public filings to extract an industry classification. It covers niche or recently formed companies that providers haven't indexed yet.
Auto-refresh keeps SIC data current
SIC codes can shift as companies pivot or restructure. Clay re-runs enrichment on a daily, weekly, or monthly schedule so your classification data stays accurate without manual re-exports.
Sync enriched records to Salesforce or HubSpot
Push the finished company name and SIC code columns directly to Salesforce or HubSpot via Clay's bidirectional CRM sync, no CSV juggling needed.
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 SIC codes?
Sculptor queries up to 10 SIC data providers, including Clearbit, ZoomInfo, People Data Labs, and HitHorizons, in a waterfall sequence. It filters companies matching your target SIC code range, builds a table of results, then runs a second waterfall across contact-data sources to attach a verified Head of Marketing email to each row.
How accurate are the SIC code results from Clay?
Clay classifies industry and SIC data as "fairly reliable" and safe to use as a hard filter. No single firmographic provider tops mid-80s accuracy, so Clay chains up to 10 sources in a waterfall to fill gaps. For the Head of Marketing email, Clay's 2025 work email benchmark showed a cheapest-first waterfall reaching 94% usable coverage at 96% accepted quality.
Can I look up SIC codes for a whole list at once?
Yes. Paste a list of company names or domains, upload a CSV, or pipe rows from an existing Clay table into Sculptor. It enriches every row with SIC codes and Head of Marketing emails in parallel. When the table is ready, push the results directly to HubSpot, Salesforce, or export as a CSV for your outbound sequence.
Is it legal to email contacts sourced by SIC code?
In the U.S., the CAN-SPAM Act applies to all commercial email, including B2B. It requires accurate sender info, a physical address, and a working opt-out mechanism, with penalties up to $53,088 per violation. In the EU, GDPR Article 6(1)(f) allows B2B outreach under a legitimate interest basis, but you must document your justification and honor data-subject requests.
Always check the rules for your jurisdiction before launching outreach campaigns.
