Global Address Verification:Result Codes

Result Code Use

Melissa Data's products use a result code system to indicate data quality; the status and any errors. These result codes are four-character codes (two letters followed by two numbers), delimited by commas. Result code definitions are shared among Melissa Data products.

Example

An example returned result code string:

AC01,AE10

Instead of looking at multiple properties and methods to determine status, you can look at the output of the results parameter.

From this output you can determine that the address is:

Code	Short Description	Long Description
AC01	Postal Code Change	The postal code was changed or added.
AE10	Premise Number Invalid	The premise (house or building) number for the address is not valid.

Be sure to reference Result Code Details for a list of Melissa Data's result codes.

Understanding the Code

To fully understand result codes, you need to know them. Knowing what codes are possible and what they indicate will be key in building an effective application. It is useful to know all the codes, but this does not necessarily mean you will use them all. Just because you have a toolbox, doesn't mean you will also try to use a screwdriver along with a hammer on a nail.
