Improve accuracy and contact rates for both Canadian and US leads

Our DOTS Lead Enhancement service bundles the power of our top five services: US and Canadian Address Validation, Email Validation, Phone Append and IP Address Validation, into a real-time API to provide a robust lead validation service, improving the accuracy and quality of your leads.

The name validation service determines the validity of the name and assigns a gender to the lead. The phone validation service appends the carrier name, exchange city and region. The address validation service corrects the address to comply with USPS or Canada Post standards and appends city, region and country information. It also determines the address deliverability (DPV) for US addresses. The email validation service corrects syntax errors and checks for deliverability. The IP address validation service appends IP location information, ISP, network owner, and a certainty code that indicates it has a high certainty of being correct.
