Melissa Data is a database of addresses recognized by the US Postal Service. The record set contains all data for all addresses in the United States. Each address is properly formatted in a way consistent with a standard the postal service recognizes. The Web Data Sharing Committee has adapted this software to be utilized as a web service allowing state agencies to add address verification to any online service or application. The committee is currently developing guidelines for this service. We encourage all interested agencies to download the Melissa Data Overview document to learn more about this valuable service and to continue to visit this website for updates. Please remember that this service is still in the beta testing phase and may be utilized only by authorized RI State agencies.
