What is Residential Delivery Indicator (RDI)?

Simple Summary

USPS RDI, or Residential Delivery Indicator, identifies whether a U.S. 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.

Benefits of RDI (Residential Delivery Indicator)

  • Lower Shipping Charges
  • Avoids Residential Surcharges
  • Reduces Incorrect Address Returns

When to Use Residential Delivery Indicators

Use USPS RDI when you would like to indicate whether someone’s address is residential or business/commercial when shipping items. Shipping things from one destination to another can be difficult at times, which is why its so important for mail carriers to know whether the address their sending packages too is one or the other to reduce the returns of those sent packages.
