Premium manufacturing data
Harris' special commitment to premium manufacturing data is supported by relationships with numerous state and regional chambers of commerce and business associations. Our database is the only one published in cooperation with the National Association of Manufacturers.

Manufacturing records feature Harris' 7,500 descriptive product categories, which offer a more detailed look at a firm's products than SIC or NAICS codes.

Commitment to quality with every profile
The foundation of all the data is D&B's DUNSRight™ quality assurance process, which features over 2,000 automated and manual checks resulting in industry-leading mail deliverability and phone connectivity rates.

The DUNSRight process is a rigorous system that makes use of data collection, entity matching, the D-U-N-S number system and corporate linkage to guarantee that all profiles are as complete, accurate and timely as possible.

Detailed fields of information
Profiles in the Harris database cover the most important details on any company. Learn more about a firm with more than 30 fields of vital information including location, contact information, industry descriptions, D-U-N-S numbers, web addresses, proprietary 8-digit SIC codes, NAICS codes, executive biographies and more.

Each profile focuses on a single business location so that coverage for branch offices is just as complete as for corporate headquarters. Names and titles of multiple decision-makers are collected for every business location, so you can find the right contact in the department you need.
