Much of the following information was taken directly from an email received from an AT&T Representative.  I have made some minor edits for clarification.


Beginning February 1st customers served by a 270 area code will be required to dial 10 digits to complete a local call.  This area is being given a new area code to make up for the lack of telephone numbers available in the area.  The new area code is 364 and will be given out for new phone numbers beginning March 1st.  Please read below for additional information regarding the change and let me know if you have any questions. 

Who Will be Affected?

The new 364 area code will serve customers in the same geographic region as the current 270 area code that generally covers the western half of Kentucky serving communities such as Bowling Green, Elizabethtown, Henderson, Hopkinsville, Owensboro and Paducah…  This is new system is known as an area code overlay.  

What Will be the New Dialing Procedure?

To complete Local calls from a landline phone, the new dialing procedure requires callers in those locations to dial the area code + telephone number. This means that all calls in the 270 area code that are currently dialed with seven digits will need to be dialed using the area code + telephone number. (This info came from AT&T, however, I strongly encourage everyone to program all their mobile phones this way too, not just landlines.  The reason for this is two-fold….I am not confident their note about this applying to only landlines is accurate, and too, when traveling with your mobile you can call your home area phones without having to key the area code.  See the next paragraph.)

To complete calls from a cellular or mobile phone, callers may continue dial the area code + telephone number whenever placing a local 270 calls.   

When Will the Overlay Change Take Place?

Beginning February 1, 2014, the customer must use the new dialing procedure for all local calls. After this date, if customers do not use the new dialing procedure, their call will not be completed, and a recording will instruct them to hang up and dial again.

Beginning March 3, 2014, new telephone lines or services in that area may be assigned numbers with the new 364 area code. (So your new next-door neighbor may have an area code of 364 rather than 270.)

What Will the Customer Need to Do?

In addition to changing their dialing procedure, all services, automatic dialing equipment, or other types of equipment that are programmed with a seven-digit number must be reprogrammed to use the new dialing procedure. Some examples are PBX, life safety systems, fax machines, Internet dial-up numbers, alarm and security systems, gates, and speed dialers, call forwarding settings, voicemail services, and similar functions. Customers may also want to check their business

stationery or advertising materials to ensure the area code is included. (This may seem unnecessary but it will become necessary as time passes.)

 What Will Remain the Same?

o The customer’s telephone number, including current area code, will not change.

o The price of a call, coverage area, and other rates and services will not change due to the overlay.

o  Calls that are local now will remain local calls regardless of the number of digits dialed.

o  Toll calls can still to be dialed with a 1 + area code + number.

o  You can still dial just three digits to reach 911, as well as 211, 311, 411, 511, 611, 711 and 811.
