A new area code is coming to Rockland County a little earlier than originally planned, but don’t worry, if you already have a beloved 845 number you won’t lose it. DailyVoice.com says because the Hudson Valley and Upstate New York regions in the 845 area code are rapidly running out of new phone numbers, the State Public Service Commission needs to start with new numbers under the new 329 area code earlier than this coming fall, as originally planned. The new 329 area code could start as soon as the end of March. Officials estimate the new 329 code won’t run out of numbers until about the year 2051.
