FRANKFORT, Ky. (AP) - Mandatory 10-digit dialing is on its way for telephone customers in western Kentucky as part of the new 364 area code being added in the region.
Officials with the state Public Service Commission say the area is halfway through a transition period that allows customers to become accustomed to the new dialing patterns.
A six-month "permissive dialing" period began in August. Customers now can dial either seven or 10 digits when making local calls in the 270 area code. Mandatory 10-digit-dialing of local calls begins this coming Feb. 1.
The 364 area code was created nearly a year ago. It will overlap the existing 270 area code, which the PSC considered the least disruptive option for customers.
Current dialing patterns in the area will remain in effect until Jan. 31, 2014.
