Overview
The Import DNC History page gives you a full record of all DNC imports carried out on your system, including both bulk additions and bulk removals. You can review what was imported, when, by whom, and how many records were affected. Selecting an import also shows you the individual phone numbers that were deactivated as part of it.
To access it, go to Data > Data History > Import DNC History. You can also reach it directly after completing a DNC import by clicking Go to DNC import history on the Import DNC confirmation screen.

Deactivated leads
Selecting an import from the Previous Imports table loads the phone numbers deactivated by that import into the Deactivated Leads section at the bottom of the page.
Use the filter icons above the columns to search through the numbers — useful when an import contains a large number of entries and you need to locate a specific record.
To export the listed numbers, click Download. This saves the current view as a CSV file, including any filters that have been applied.
