RDI, or Residential Delivery Indicator, identifies whether a US address is classified as residential or business. Most shipping companies charge a higher price for residential deliveries. Businesses can use RDI data to maximize savings by flagging residential addresses and then shopping for the most cost-effective delivery option.

CDYNE's PAV API includes RDI data as part of its Postal Address Verification solution and does not charge extra for this service. Click here for a full list of all PAV return values.
