DirectoriesUSA has the most accurate sales and marketing data available.
DirectoriesUSA's business and consumer databases are powered by infoGROUP®. Each day, infoGROUP data specialists scour thousands of sources to add new data,
update existing records, and eliminate duplicates.
Their process is like no other in the industry. They call every business to ensure you get the most accurate and complete information available.
infoGROUP's research staff places more than 26 million phone calls a year to maintain the accuracy of the listings, as well as capture additional information.
How we compile our data:
- We scrutinize and catalog 5,200 telephone books, annual reports and other business directories.
- Next, we add public record data from county courthouse filings, SEC and 10K filings, and Secretary of State data to find information on nearly every business and consumer in the nation.
- We call every business and hand key each record to make sure you have the most reliable information available.
- Our data specialists also examine each consumer listing to enhance it with buying habit and lifestyle information from real estate transactions, product registrations, magazine subscriptions, and survey responses.
- Every month we match and clean the business and consumer data with the USPS National Change of Address (NCOA), ZIP+4 and Delivery Sequence File to standardize and keep the addresses accurate.
