DOTS Address Validation – US 3
What DOTS Address Validation – US 3 is
DOTS Address Validation – US 3 is an API service for validating, correcting, and standardizing US mailing and shipping addresses against USPS data. The maker says its engine covers over 160 million USPS addresses plus 15 million non-postal addresses, using USPS CASS-certified matching and delivery point validation. Results can include corrected street locations and ZIP+4 information, along with parsed details such as PMB numbers, directional indicators, county codes, and state codes. The recommended GetBestMatches operation is joined by operations for secondary number lookup, RDI validation, SuiteLink, parsing, city/state/ZIP checks, and single-line matching. AV3 is a public XML web service supporting SOAP, POST, and GET, with RESTful or simple HTTP transport calls. It is intended for instant website verification and contact-list enhancement. Sample code is listed for PHP, Java, and C#, and the maker names Salesforce, Marketo, and HubSpot as possible CRM integrations. A free API trial key includes 500 transactions. The maker advertises a 99.999% uptime guarantee and 24/7/365 support with dedicated support engineers, but cautions users to consider output carefully before deciding whether an address exists.
