Whether you’re doing research for an upcoming interview, gathering business intelligence, writing a school paper or looking up a cousin you have lost contact with, you need the most accurate data available. That’s why you need ReferenceUSA.

ReferenceUSA, an Infogroup company, provides the highest quality data in the industry. We have a 130,000-square-foot Database & Technology Center dedicated to building the world’s most comprehensive and accurate databases. Each record is examined by hand for quality and completeness by one of our over 350 database specialists. Our business and residential databases are continuously updated from more than 5,000 public sources. We place in excess of 24 million phone calls per year to verify and collect additional information on businesses.

Our database of 24 Million U.S. Businesses is the most accurate and comprehensive in the industry. The lists include company name and phone number, complete address, key executive name, SIC Codes, employee size, sales volume, business expenditures and much more. In addition to basic company names and addresses, we add valuable details, including: geo-codes for mapping, fax and toll-free numbers, website addresses and franchise information, headline news, liens, judgments and bankruptcies, email addresses, number of computers, work-at-home businesses, and business credit rating scores.

ReferenceUSA’s residential information is compiled from more than 5,200 White Page telephone directories. Each listing appears in the database exactly as it appears in the phone book. ReferenceUSA does not include unlisted phone numbers, Direct Marketing Association and Canadian Marketing Association suppression files, or state-regulated mail and telephone suppression files (U.S. data only). Information is available eight to twelve weeks after it appears in the phone book, and the file is processed through U.S. and Canadian National Change of Address records on a weekly basis. Each U.S. residential listing also contains information from the most recent U.S. census, including median household income, median home value, latitude/longitude and percentage of owner-occupied housing.

More than 4 million customers use our products and services for direct marketing, telemarketing, market research, sales lead generation, sales planning, customer analysis and credit decisions.
