Area Codes |
Splits maintain a single area code for each geographic area. |
Overlays have two or more area codes within a single geographic area. |
Telephone Numbers |
Splits require an area code change for approximately one-half of the customers. |
Overlays do not require existing customers to change their area code. |
Local Calling |
Splits permit 7-digit dialing for local calls within the area code. |
Overlays require 10-digit dialing for all local calls. |
Consumer Expenses |
Printed materials such as stationery, business cards and advertising must be revised by those customers receiving the new area code. |
There is no need to revise any printed materials unless they contain only 7-digit telephone numbers. |
Size of the Area Code |
Splits reduce the geographic size of the area code. |
Overlays maintain the current size of the area code. |
