DQ*Plus takes your bad data and gives you back clean and accurate data (like addresses). DQ*Plus standardizes your data so that it presents uniformly to your customers and makes records easier to find. Further, DQ*Plus enhances your data by updating it with newer or more accurate information.

US Address Cleansing - The DQ*Plus address verification engine is CASS Certified™ by the USPS®. DQ*Plus address processing uses the latest USPS data file of over 38 million records to validate addresses to the street number range and apply the ZIP+4® code. DQ*Plus also provides Delivery Point Validation (DPV™), which can validate the existence of an address to the street number and secondary unit number based on the latest USPS data file containing over 151 million delivery points. Additional data may be appended during address processing, such as carrier route code, delivery point barcode, county name, latitude and longitude coordinates and time zone.

International Address Cleansing - DQ*Plus corrects, verifies and standardizes address data for over 200 countries using rules that comply with postal standards and address data files provided by the postal authorities from each country.

Census - DQ*Plus adds U.S. census data to your customer records based on Zip Code. This information includes population, a breakdown of ethnicity, age, education and income.
