The SuiteLink database contains suite numbers for business addresses in selected high-rise buildings and targets high-rise addresses with high-volume default mail. The SuiteLink database improves the business addressing information through assignment of suite numbers. The

USA5C18.MD

file contains the latest data from the USPS. If the input address contains firm or company information, Address Verification initiates the SuiteLink verification.

Address Verification also sends records with input suite data that do not match with the ZIP4 file thorough the SuiteLink process. If Address Verification finds a match for such addresses while verifying against SuiteLink, Address Verification retains the input suite data in the residue component and output in DAL2. The USPS requires the address verification operation to retain the extraneous data.

The Residential Delivery Indicator (RDI) processing verifies whether the input data maps to a residence address or a business address. The

USA5C22.MD

and

USA5C23.MD

databases contain RDI processing-related information. RDI processing returns either Y or N based on the nature of the address. If Address Verification finds a ZIP9 or ZIP11 match for the input address, Address Verification marks the address as business delivery and returns a value of N. If Address Verification does not find a ZIP9 or ZIP11 for the input address, Address Verification marks the address as residential delivery and returns a value of Y. The RDI processing is useful for parcel shippers.
