Result Code Use

Melissa 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 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 address is:

Code Short Description Long Description
ES01 Valid Email Domain The email domain name was confirmed as valid by either the DatabaseLookup or MXLookup.
ES04 Mobile Email Address The domain name was identified as a mobile email address and classified as not deliverable by the FCC.

Be sure to reference Result Code Details for a list of Melissa 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.
