The RDI™ Product allows customers to determine whether an address is classified as residential or business in the USPS® Address Management System (AMS) database. Addresses processed using the RDI data return an indicator denoting ‘Yes’ for Business or ‘No’ for Residential. Important Links The RDI Product should be used in conjunction with CASS Certified™ ZIP + 4® address matching software and may be used on any platform. Product updates are provided on a monthly basis. The RDI data is supplied as hash tables. The standard hash algorithm is only determined for the 9-digit and 11-digit ZIP Code rather than the entire address. The 9-digit hash table consists of ZIP + 4 codes that contain only business deliveries. The 11-digit table consists of the delivery point codes for the business deliveries where the ZIP + 4 code contain both business and residential deliveries. The RDI Product can be used for internal purposes or provided as service to third parties. Additionally, the RDI data can also be redistributed to third parties. Annual License Fee: $335.00* To develop RDI-enabled software, you should be or in the process of becoming a CASS software manufacturer. If interested in becoming a CASS software manufacturer, contact the CASS™/MASS™ Department at 800-642-2914. For more information on AIS Products, please contact Customer Care at 800-238-3150.

On the Move The National Customer Support Center (NCSC) is moving its office location. Starting Dec. 1, the new address for the NCSC will be: NATIONAL CUSTOMER SUPPORT CENTER The NCSC works closely with the mailing industry, vendors and internal postal customers to improve address quality. The USPS headquarters office of Address Management also is located at the NCSC. Numerous USPS publications, forms, brochures, etc. currently provide the existing address for the NCSC – all of which will need to be updated, including those on usps.com and other postal websites. Telephone numbers for all NCSC personnel and program support groups will remain the same. |
