On my initial file submission, how do I know when I should update my data?

There is a Correction Opportunity column that tells you if D&B has a more deliverable address that you should be using. When the Correction Opportunity has a value of �C�, we recommend you use our address information from the appended Strategic Database Marketing Record. If the correction Opportunity has a value of �N�, your data is current and there is no need to update it.
