ReferenceUSA is a reference service from the Library Division of InfoUSA. The site was designed for use as a reference tool in libraries and is continually enhanced based upon suggestions from librarians and library patrons.  ReferenceUSA databases offer up-to-date and thoroughly verified details and demographics on US and Canadian households and businesses. Each database is a compilation of facts and figures from sources ranging from telephone books to SEC reports to industry directories and postal change of address data. Then, information is carefully fact-checked via one-on-one telephone interviews.

ReferenceUSA's behind-the-scenes work exemplifies the highest dedication to maintaining current data:

• 20 million phone calls are made each year
• Businesses with 100+ employees are phone-verified at least twice a year
• On an average month, over one million changes are made to the US Business database
• Over a year’s time, 80% of the database changes
