DOTS Phone Append 2 is a real-time API that enables you to append missing consumer and business phone numbers to your contact data records by cross-referencing their name and address against large authoritative datasets. Phone Append also validates and standardizes the submitted street addresses while providing the phone number’s line type. Our proprietary database is updated daily with over 800 million consumer, business and government phone number listings, resulting in industry-leading match rates up to 75%. With this service, companies ensure that their customer contact records are complete and always up-to-date.
