Hi,

Please help me in uinderstanding below questions.

1)How CASS evaluates DPVCodes&MatchFlag fields internally?
2)And based on these fields how do we decide whether given Address is valid or not?

Please let me know.

Hi,

Take a look at the doc - it does a pretty good job of defining the codes.

The codes are set according to US Postal Service rules and certification requirements.

Please let me know which document I need to look into to understand CASS functionaliy .

And also let me know what would be the reason when my job using CASS for address validation, returning
ADDRVAL_MatchFlag_Cass -> NULL
ADDRVAL_DPVCode2_CASS-> NULL
ADDRVAL_DPVCode3_CASS -> NULL.

Hi,

There is a PDF in the installation package. Please ask your administrator.

Also, a quick Google search turned up http://publib.boulder.ibm.com/infocente ... cmain.html
