What DOTS Address Validation – US 3 is
DOTS Address Validation – US 3 is a paid API and web service for validating, correcting, and standardizing United States mailing and shipping addresses against USPS data. Service Objects says its engine covers over 160 million USPS addresses plus 15 million non-postal addresses. USPS CASS-certified matching and delivery point validation support the checks. Results can include corrected street locations, ZIP+4 information, and parsed tokens such as PMB numbers, directional indicators, county codes, and state codes. GetBestMatches is the recommended operation, with additional functions for secondary numbers, RDI, SuiteLink, parsing, city/state/ZIP validation, and single-line matching. AV3 provides XML web-service access through SOAP, POST, and GET, with RESTful or simple HTTP transport. Sample code is listed for PHP, Java, and C#. The API can support website verification and contact-list enhancement, with named CRM integrations including Salesforce, Marketo, and HubSpot. A free trial key includes 500 transactions. The maker advertises a 99.999% uptime guarantee, 24/7/365 support, and dedicated support engineers.
