What does the Residential Delivery Indicator or RDI indicate?
Residential Delivery Indicator or RDI is licensed by the Postal Service and works with certified CASS™ software or an address standardization tool provider to verify delivery type status.
As a matter of fact, Residential Delivery Indicator has several benefits. First, RDI will validate delivery type status; therefore, reducing residential delivery surcharges and shipping costs. Next, avoid the use of incorrect addresses by using the RDI. This, in turn, reduces returned mail. Finally, it improves mailers' shipping processes by giving analysis of shipping patterns. There are many more benefits to RDI. You can read more about the benefits of RDI here.
