Each record that receives an Echelon score will have a Disposition code explaining why the address received that score. The possible disposition codes are below:

1We were able to find ZIP & ZIP+4 provided and we were also able to use all the data

required by the formula from the input file. An example is using the age and income provided
by you to compute a requested variable.
2The input ZIP or ZIP+4 is invalid. This condition occurs if the ZIP has non numeric values

inside the key, or is outside the range of our valid ZIPs or ZIP+4s.
3We could not find a matching ZIP/ZIP+4 in our roster of ZIPs. In this case treat the values

of any of the appended measures as not valid.
4We did not get age from the input file.
5We did not get income from the input file.
