Area code 212 usually represents "New York" in people's minds, but as telecommunications grew more complicated, demand began to exhaust the original citywide area code. Area code 929 is one of the newer additions to the family of city numbers, and it overlaps with 718 and 347. When announcing the new area code Neustar estimated that 718 and 347 numbers would be exhausted by 2012, and with the addition of 929, that estimate was extended to 2029.

New York's most recent area code is 332, which was assigned to Manhattan in 2017. As of April 2020, NANPA, the organization in charge of assigning area codes, estimates that New York City's available phone numbers will begin to be completely depleted by 2030, although those estimates have been increasing as fewer new numbers have been needed in recent years. With the shift toward mobile phones and the portability of numbers, New York area codes can now travel across the country, bringing along the legacy of having once been assigned to someone living in New York City.
