RDI™
Business or residential? Make informed decisions, improve your deliverability, and optimize operational efficiency with RDI™.
Who is RDI™ for?
The RDI™ product is designed for use alongside CASS Certified™ ZIP + 4® address matching software and is compatible with any platform. Updates to the product are released monthly. The RDI is provided as hash tables, not as a flat file, and requires integration with either your own, a third-party or our CASS Certified™ ZIP + 4® Address Matching software. Customers attempting to develop third-party RDI-enabled software must be currently or in the process of becoming a CASS software manufacturer. Access to the RDI Developer’s Guide and test data is granted exclusively to subscribers of our CASS Certified™ ZIP + 4® Address Matching software. Utilizing the RDI file necessitates the development of a CASS certified API or the use of a third-party Address Matching engine. A list of CASS Certified™ ZIP + 4® vendors is available here.
For first-time RDI purchasers, please reach out to our Customer Care department at AISProducts.NCSC@usps.gov before placing an order.

Description
The RDI™ is a data product that verifies whether a delivery type is classified as residential or business. Designed specifically for shipping parcels, this distinction between delivery types is valuable due to the fact that some shipping companies charge higher fees for residential delivery. By having the additional data provided by RDI, it’s possible to determine shipping rate information with greater accuracy, analyze parcel shipping patterns and costs, and ultimately, make informed decisions about the most cost-effective means of conducting shipments.
What are the benefits of using RDI™?
-
Reducing residential delivery surcharges by validating delivery type status for the purpose of choosing parcel shipping suppliers.
-
Providing analysis of parcel shipping patterns and costs for the purpose of improving mailers’ parcel shipping processes.
-
Lowering shipping charges by providing rate-shopping services to clients, which will allow them to compare parcel shipping rates for input addresses.
-
Reducing returns due to incorrect addresses by using RDI™ in conjunction with CASS™ software.
-
Enhancing Customer Relationship Management (CRM) by demonstrating efficient and accurate shipping practices.
-
Identifying shipping patterns to improve operational efficiency.
- Providing online rate-shopping services for others.
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.
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 a service to third parties. Additionally, the RDI data can also be redistributed to third parties.
Annual License Fee: $560.00*
