Why large data buyers come to us
Large data orders are where SICCODE.com is strongest. When you need thousands, hundreds of thousands, or millions of records, we can usually build a better-scoped file with better per-record economics than buying small lists one at a time.
The biggest value is not just record count. It is getting the right companies, the right classifications, and the right fields in a file your team can actually use.
What we can build
Files can be scoped by industry, geography, SIC code, NAICS code, company size, executive role, website presence, email availability, and other business attributes.
Large business files
Company name, address, phone, website, location type, sales range, employee range, SIC, NAICS, and related firmographic fields.
Executives and emails
Executive names, titles, company links, and business email data when requested. Email files receive verification review before delivery.
SIC and NAICS appends
Add primary SIC and NAICS codes, industry titles, hierarchy rollups, and crosswalk support to your existing company or customer file.
Industry-specific databases
Build a custom data set around the real market you want, not just a broad code. We can combine codes, subcategories, geography, and review rules.
What to include in your request
A good request does not need to be perfect. Include as much as you know, and we can help refine the scope.
How many records?
Tell us whether you need thousands, hundreds of thousands, or millions of records.
Who do you need?
Include the industries, SIC/NAICS codes, company types, geography, or exclusions that matter.
What fields matter?
Tell us if you need contacts, emails, websites, industry codes, firmographics, or custom fields.
How will you use it?
Internal analysis, marketing, appending, licensing, redistribution, and refresh schedules affect scope.
Classification accuracy matters at scale
Large files become expensive when the industry scope is wrong. We use SIC and NAICS structure to define the target market first, then review the file for obvious mismatches, weak category fits, duplicates, missing fields, and records that do not match the requested industry.
