The Change Area Code tool is useful when area codes are changed in one of your primary market areas; it allows you to quickly change all customers affected to their new area code. In order to run this tool, you must create a text file that lists the old area code, the phone extension (first three digits of the phone number), and the new area code for that extension. The fields must be comma-separated. For example, if area code 612 was changing to 651 for all phone numbers starting with “222”, “211” and “639”, you would have the following lines in your file:
612,222,651
612,211,651
612,639,651
Select Change Area Codes from the Utilities | Tools menu.
Select Add and enter the path and file name of the text file you created.
Select Continue to change the area codes. A processing report will display the number of records changed.
