UNDATED (WHBL) - A new telephone area code for northeast Wisconsin is being delayed indefinitely – and that means folks in the 9-2-0 area code will not have to dial 10 digits for their local calls. The State Public Service Commission was planning to make all new phones in the 9-2-0 region use an area code of 2-7-4, and make all phone customers dial an area code – even for calls across the street. But the P-S-C says such a move won’t be needed for a while, because it will take longer than expected for phone numbers in the 9-2-0 area code to be all used up. The stagnant economy is one reason for the delay – and the P-S-C says effective conservation measures have also been taken. As a result, all the possible 9-2-0 numbers won’t be exhausted until late in 2017. Officials say a new schedule for implementing 2-7-4 will be adopted within two years before the 9-2-0 numbers run dry. Phone customers in central and northern Wisconsin are already dialing 10 digits for all their local calls. That’s because a separate area code was added for new numbers in the 7-1-5 territory a couple years ago.
