Company directories and business databases remain one of the most widely used channels for B2B customer development. Compared with social media or cold advertising, these platforms provide structured company information, clearer industry classification, and relatively higher data reliability. Below is an overview of several mainstream company directories and databases that are commonly used by importers, exporters, and international sales professionals.

1. Tendata

Website: tendata.com

Tendata aggregates company directories from multiple countries and industries. Most registered companies provide essential contact details such as websites, phone numbers, and fax information. Users can search target companies by product keywords or browse by industry categories.

Unlike traditional yellow pages, Tendata can also be combined with trade data to verify whether a company has real import or export activity, making it more suitable for precise customer development.

2. Yell (United Kingdom)

Website: yell.com

Yell is one of the most well-known national company directories in the UK. It is particularly strong in British SME data and allows users to search companies by industry, location, and business name. For those targeting the UK market, Yell remains a valuable starting point for lead generation.

3. Dun & Bradstreet (D&B) / Hoovers

Websites: dnb.com | hoovers.com

Dun & Bradstreet is a global leader in business information and credit reporting. It is estimated that D&B holds data on over 90% of small and medium-sized enterprises in the United States.

Hoovers is one of D&B’s major platforms, offering company profiles, executive contacts, financial insights, and industry analysis. Businesses can also search companies using D-U-N-S® Numbers directly on the D&B official website.

4. Thomasnet

Website: thomasnet.com

Thomasnet is a long-established industrial directory and one of the most comprehensive business databases in the United States. It is especially useful for sourcing manufacturers, suppliers, and industrial service providers across various sectors such as machinery, electronics, and raw materials.

5. Superpages

Website: superpages.com

Superpages allows users to refine searches down to specific regions, states, cities, or even neighborhoods. This makes it particularly helpful for localized B2B development or when targeting distributors and service providers in a specific geographic area.

6. Yahoo Local Search

Website: local.yahoo.com

Yahoo Local Search integrates business listings with maps, phone numbers, and official websites. While not strictly a B2B database, it can be useful for verifying company existence and gathering basic contact details, especially for small and local businesses.

7. Jayde

Website: jayde.com

Jayde is a traditional B2B search engine that focuses on industrial products and suppliers. Although its interface is relatively simple, it still provides value for niche product searches and supplier discovery.

8. Kompass

Website: kompass.com

Kompass is a globally recognized B2B database frequently used by suppliers worldwide. It offers structured company profiles, product classifications, and industry segmentation, making it suitable for systematic lead generation across multiple countries.

9. Better Business Bureau (BBB)

Website: bbb.org

The Better Business Bureau lists verified businesses in the United States and Canada, similar to enterprise credit or integrity certifications in other countries. BBB-listed companies generally have good reputations and higher trustworthiness.

However, searching directly on the BBB website can be inefficient. A common workaround is to use search engines with queries such as:“product keyword site:bbb.org”

This method helps identify BBB-accredited companies that can be considered high-quality potential customers.

Conclusion

Mainstream company directories and databases are still essential tools for B2B sales and international trade development. They are particularly effective for initial lead discovery, company verification, and market research. However, to improve efficiency and conversion rates, many professionals combine these directories with trade data platforms like Tendata to confirm real purchasing behavior and prioritize high-potential buyers.
