A USA business directory you don't have to be listed in
Almost everything that calls itself a USA business directory is a citation site. A business gets a page only when its owner adds one, usually to collect reviews or pin itself on a map, sometimes for a monthly fee. That is fine if you are marketing to consumers and useless if you need the whole market. This directory is built the other way around, from the official record. Every one of the 64 million businesses in it is here because it registered with a Secretary of State, the IRS, or a federal trade register, not because it opted in.
So you are not searching the businesses that wanted to be found, you are searching all of them. Each entry carries the legal name, registration ID, registered address, and industry classification, with revenue, employees, executives, and corporate ownership on the larger companies. Look one up by name or EIN, narrow by state or industry, and it stays free. When you need the records in bulk instead of one at a time, export to Excel or pull them straight through the API.
Searching businesses one at a time? Do it programmatically instead. The CompanyData API returns the same registry records as structured JSON, and your key starts with 150 free lookups. Explore the SEC EDGAR API

Frequently Asked Questions
Common questions about searching, filtering, and ordering business records.
Our USA business directory currently lists more than 64 million verified American businesses across all 50 states and DC. The number is updated continuously as new entities register and inactive ones are removed.
SIC (Standard Industrial Classification) is the older 4-digit US industry code system. NAICS (North American Industry Classification System) replaced it in 1997 with a 6-digit hierarchy used across the US, Canada, and Mexico. Our directory supports lookup by both. Most US business registries still publish SIC codes alongside NAICS.
We deliver US business data through four channels to fit your workflow: REST API for automated pipelines, tailored Excel mailing lists for targeted outreach, high-volume bulk packages for global data buyers, and the CompanyData platform for self-serve, on-demand list-building. Tell us your target audience and we'll match the right channel.
