Certified Mode Verification of United States Addresses

Certified Mode Verification of United States Addresses

You can use certified mode to verify United States addresses in accordance with the CASS guidelines of the United States Postal Service.
Certified mode verification of United States addresses is available only to customers in the United States.
To verify United States addresses in certified mode, you install the United States
Cx
databases. The
Cx
databases are numbered
USA5C101.MD
through
USA5C128.MD
. The databases enable the address verification process to analyze and update different aspects of the address according to the different USPS postal criteria. Add the unlock codes for the files to
SetConfig.xml
.
The following table summarizes the types of data in the databases:

Note the following:
  • Do not combine any CASS file numbered
    USA5C101.MD
    through
    USA5C128.MD
    with any CASS file numbered
    USA5C1.MD
    through
    USA5C26.MD
    . The file types are not compatible.
  • The CASS certification files that the United States Postal Service provides comply with the SHA-256 standard.
  • Address Verification does not currently read the following files:
    • USA5C105.MD
    • USA5C106.MD
    • USA5C107.MD
    • USA5C108.MD
    • USA5C109.MD
    • USA5C110.MD
    • USA5C119.MD
    Informatica delivers the files for users who run older versions of Address Verification. Address Verification does not preload the files into memory.
  • The DPV database has information that helps you check whether a ZIP+4 coded address is in the USPS delivery file as a known address record. You can use the DPV product to confirm known USPS addresses and to identify potential addressing issues that might affect delivery. If you do not install the certified databases, Informatica Address Verification adds ZIP+4 Codes to United States addresses if the
    USA5BI.MD
    database is available.
  • Informatica Address Verification sends records with input suite data that does not match the ZIP+4 Code reference data thorough the SuiteLink process. If Address Verification finds a match for such addresses with SuiteLink, Address Verification retains the input suite data in the residue component and writes the correct suite data in DAL2. The USPS requires that the address verification operation retains the non-matching input data.
