| <2> | The elevation is an estimate for the area around Ronkonkoma - it will be higher in some places and lower in others. |
| <3> | When there's a risk of an area code running out of phone numbers, an 'Overlay Area Code' is created that has the same geographic boundaries as the existing area code. In this case, the 631 code has been Overlayed with the 934 area code. New phone numbers in the Ronkonkoma area will be assigned with one of these codes: 631 or 934. As a result, placing a call in the Ronkonkoma area will require 10-digit dialing (where you enter both the area code and then the phone number). |
