631-XXX-XXX Phone Numbers

Area code 631 was officially put into service on November 1, 1999. Created from a split of area code 516, it now covers almost all Suffolk County. Initially, the 631 area code was to be overlaid with area code 934 in 2016, but it split into two different operational areas later. This move was an answer to the extent of demand for new phone numbers in the region, which had led to a risk of number exhaustion.
