This service utilizes the latest .Net Framework, WCF, and can be used as a RESTful service or with SOAP. AV3 is designed to take an unstandardized address, validate it against the latest USPS data, and return standardized, deliverable addresses. The service provides corrected information such as the correct street location and zip plus four code, along with parsed address tokens, such as the PMB box number, pre- and post-directionals, county and state codes, and much more.<\/p><p>AV3 can provide instant address verification and correction to websites or enhancement to contact lists.\u00a0 However, the output from AV3 must be considered carefully before the existence or non-existence of an address is decided.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c7a953c wp-block-group
