The USPS provides a delivery status indicator for each address. They call this the Residential Delivery Indicator (RDI). It's an incredibly useful tiny little piece of information. If you are shipping packages, the RDI data allows you to shop around for the most cost effective shipping solution based on the residential/commercial status of the address. Many businesses add and additional shipping charge for residential addresses. Our service allows you to know before you ship, if there is going to be a residential surcharge and you can then plan accordingly. Either pass that charge on to the consumer while they are still placing their order or just absorb it. Either way, it puts you in charge.
Here is an example address showing the RDI data:
1600 Amphitheatre Parkway Mountain View, CA 94043
1600 Amphitheatre Pkwy Mountain View CA 94043-1351
