WHAT IS AN AREA CODE OVERLAY? IS THERE ANY ADDITIONAL COST FOR AREA CODE OVERLAYS?
An area code overlay is an area code that has been assigned to the same geographic area as at least one other area code. An overlay does not require existing customers to change their area code or phone number. Numbers from this new area code may be assigned to new telephone customers or those adding additional lines.
When you license an area code that has an overlay, the overlay area code is automatically included. This means there is no additional cost and you don’t have to purchase the rights for the overlay area code separately.
