New 331 area code to overlay 630

November 17, 2010
Thank the Illinois Commerce Commission for approving another area code overlay instead of carving out a separate region to be assigned a new area code. 

 

The result: All calls in the 630 area code that currently are dialed with seven digits will need to dialed, beginning Oct. 7, with 11 digits—1 + area code + telephone number.

 

Callers in the land of area code 847 have faced the same imposition since the 224 overlay was introduced in 2002. The overlay forces calls even to a next-door neighbor to include dialing the area code. In 630-land, the new area code is 331.

 

In addition to changing dialing procedures, businesses might have to adjust all service, automatic dialing equipment, or other types of equipment that are programmed with a seven digit number. The devises will need to be reprogrammed to use the new dialing pattern. Some examples are:

 

  • Call Forwarding Settings
  • Life Safety Systems
  • Fax Machines
  • Alarm and Security Systems/Gates
  • Speed Dialer
  • Voicemail Services and Similar Functions
