How accurate are your databases?
InfoUSA is dedicated to having the highest quality data in the industry. Each record is examined by hand for quality and completeness by one of our over 600 database specialists.

Business Database Accuracy

Our database specialists continuously update our business databases from over 5,000 public sources. We also place more than 20 million phone calls per year to verify and collect additional information. With our data, you can expect to have the highest deliverability rates in the industry with only 5-10% undeliverables. You can even expect higher deliverability rates in industries with lower levels of turnover.

Consumer Database Accuracy

InfoUSA's consumer database specialists continuously update our records from new sources on a monthly basis. The database is also processed against both the USPS National Change of Address File (NCOA) and the Delivery Sequence File (DSF). InfoUSA's information is carrier route and ZIP+4 coded using the US Postal Service certified Coding Accuracy Support System (CASS). Even though consumers move on a regular basis, the quality of the InfoUSA's consumer data will allow you to reach a 90-92% deliverability rate, an unmatched level in the industry.

How do you compile your databases?
We have a 130,000-square-foot Database & Technology Center dedicated to building the world's most comprehensive and accurate databases. We employee 600 associates and spend $50 million dollars a year to compile and update each record within our databases. It's a process no one else takes the time to complete.

How can I add my consumer information to your database?
Our consumer database is compiled primarily from local phone directories. Due to issues of privacy, we are not able to add or change any listings to our residential database based on requests. Records are updated upon receipt of the local telephone directory. We will not add or change information based on requests because we cannot verify this information.

When can I expect to see the results of a database add/change request?
Business records must be telephone verified before they can be added or changed in the database. This process may take up to 60 days.

What are Credit Rating Codes?
InfoUSA has developed a sophisticated computer model to assign credit ratings to the companies in our business database. InfoUSA's model considers information such as: number of employees, years in business, industry stability, census data and other factors to arrive at credit ratings that are practical, and statistically sound indicators of probability to pay.
