What is an Overlay Area Code?
An overlay area code, such as area code 224, is a second area code that is introduced to the same geographic area as an existing area code, like area code 847, allowing for an increase in available telephone numbers. This system necessitates ten-digit dialing, which requires callers to dial the full 10-digit telephone number, including the area code, to ensure proper call routing. Overlay area codes have become a common solution in regions experiencing rapid population growth and demand for telecommunication services.
This approach provides several benefits, including the ability to assign more numbers to a densely populated region without the need for geographical splitting. By maintaining the same geographic area, existing customers retain their numbers, which helps streamline the transition for businesses and residences alike.

New subscribers can easily obtain numbers without navigating the complications that can arise from reassigned area code boundaries.
The implementation also presents challenges. The requirement for ten-digit dialing can be cumbersome, particularly for those accustomed to the older system. Businesses must update their marketing materials to reflect the newly established dialing procedures, which can lead to confusion and increased operational costs.
