Result Code Use

The list of all result codes can be found here: Result Code Details.

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.


An example returned result code string:


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 phone number is:

Code Short Description Long Description
PS01 Valid Phone The phone number is valid.
PS22 High Confidence Number was verified against current dialing equipment.

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.
