Automatic time zone mapping examples


When a contact list is configured for automatic time zone mapping, the system evaluates the phone number and zip code column values to determine the compliant dialing time for each contact.

Tip: You can override a default dialing window for automatic time zone mapping on the Outbound Settings screen.

The table below shows how the system behaves when it evaluates a record containing two phone numbers and a zip code.

Zip code  Phone number 1 Phone number 2 Compliant dialing time
Could not map Could not map Could not map 2:00 PM to 8:00 PM Eastern time (default) 
Could not map Eastern time Could not map 2:00 PM to 8:00 PM Eastern time (default) 
Not available Central time Eastern time

9:00 AM to 9:00 PM Eastern time or
8:00 AM to 8:00 PM Central time

Not available Could not map Central time 8:00 AM to 9:00 PM Central time
Central time Could not map Central time 8:00 AM to 9:00 PM Central time

Central time Could not map Could not map 2:00 PM to 8:00 PM Eastern time (default) 
Not available Central time Central time 8:00 AM to 9:00 PM Central time
  • Could not map (zip code) = The system could not map the zip code number column value because it is not a valid US zip code.
  • Could not map (phone number) = The system could not map the phone number column value because it is not a valid NANP number.
  • Not available = The contact list does not include a zip code column or the zip code column value for the contact is blank.
Note: The system stops dialing one minute before the end of the compliant dialing time to provide a buffer to complete record processing.
