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.
Address Verification (AV) Codes
- AV2X denotes an address that has been verified to the highest possible level with the reference data.
- AV1X denotes a partially verified address, but NOT to the highest level possible with the reference data.
- The second number indicates the level of verification. There are five levels:
- Administrative Area(level 1) verification is the most general verification area, with SubPremises(level 5) being the most specific area.
- Ideally, all addresses should be verified to Premises(level 4) or SubPremises(level 5.) However this is dependent on the quality of the address data and the countries’ reference data. Some countries lack enough data to be verified to the SubPremises. They may only have data to the Locality(level 2.) This is why it is possible to have an AV22 code. The address has been verified up to the Locality and the reference data only has verification up to that level.
