Where directory data begins

We draw from publicly available sources to assemble directory profiles. These sources are starting points, not guaranteed truth.

Overview

This page summarizes the kinds of public sources we reference and how attribution is handled for transparency.

We use publicly available sources and do not claim affiliation with listed platforms. The goal is to point you back to original, authoritative references whenever possible.

Primary sources

Primary data sources

These categories describe the types of public references that inform listings.

Public registries and open data catalogs, such as Data.gov, the U.S. Census Bureau, SEC EDGAR, SAM.gov, and the IRS Tax Exempt Organization Search.
Government and standards bodies, including NAICS industry classifications and ISO 3166 country codes.
Company-provided public information (for example, official websites and press rooms).

Reference approach

How we reference sources

When possible, we link directly to the source of record.

External links are used to point to the original source so you can verify details independently. We distinguish between a source of record (the official organization or registry) and an aggregation that summarizes public information. When we provide contextual fields, they are meant to guide research rather than replace the primary source.

For general terminology used across public datasets, we also reference resources such as Schema.org for baseline definitions.

Licensing

Licensing & attribution

Licenses vary by source and should be reviewed on the originating site.

We respect attribution requirements and link back to official sources where possible. Always review the source license terms on the authoritative site before reuse or redistribution.

Quality

Data quality and limitations

Public data can be incomplete or inconsistent across regions and industries.

Coverage can vary by geography, industry, and source availability.
Public information can become outdated between source updates.
Company names and addresses may have alternate spellings or formats.
Duplicate listings can occur and are reviewed for consolidation.
