Start of Permissive 10- digit Dialing

Saturday,
10-17-2009

12:01 a.m. CST

During the permissive dialing period, customers are encouraged to begin using 10-digit dialing to place all local calls (the 3-digit area code + the 7-digit local number).  However, local calls will still complete if a caller dials only the 7-digit number.  
Start of Mandatory 10-digit Dialing

Saturday,
7-17-2010

12:01 a.m. CST

Once mandatory 10-digit dialing begins, callers must use the 3-digit area code and the 7-digit number for all local calls.  Calls incorrectly dialed will reach a recording indicating that it is necessary to dial the area code and the 7-digit telephone number.
Earliest NXX code Activation Date**

Saturday,

** This is considered the effective date of area code relief in the 715 area.
