The Complete Breakdown of All Active New York Area Codes (NPA)

New York State is one of the most complex numbering plan areas in the country, featuring a total of 18 active area codes that serve 13 distinct geographic regions. The state uses a system of overlay codes, where a new code is added to the same geographic region as an existing code, requiring mandatory 10-digit dialing for all calls within that area. Here is the full list, organized by region, including the newest additions.

New York City (NYC) Area Codes: The Five Boroughs

New York City is split into two primary numbering plan areas: Manhattan (the original code) and the four Outer Boroughs. Due to the massive demand for phone numbers, both regions have multiple overlay codes, making 10-digit dialing the standard across the entire city.

• 212: The original, iconic Manhattan area code, covering only the borough of Manhattan. It is one of the most sought-after codes in the world.
• 646: The first overlay code for Manhattan, introduced in 1999 to supplement the exhausted 212 numbers.
• 332: The newest active overlay code for Manhattan, introduced in 2017 to meet continued demand. It shares the same geographic area as 212 and 646.
• 718: The original area code for the Outer Boroughs: The Bronx, Brooklyn, Queens, and Staten Island, plus the Marble Hill section of Manhattan. This code was created in a 1984 split from 212.
• 347: The first overlay code for the Outer Boroughs, introduced in 1999 to supplement 718.
• 929: A second overlay code for the Outer Boroughs, implemented in 2011.
• 917: A unique, universal overlay code that covers *all five* boroughs of New York City (Manhattan, Brooklyn, Queens, The Bronx, and Staten Island), as well as Nassau and Suffolk counties on Long Island. It was originally intended for mobile phones but is now used for all services.

The Newest NYC Area Code: 465 (Scheduled for 2026)

The demand for new phone numbers in the Outer Boroughs (718/347/929) has officially exhausted the supply. To address this, the New York State Public Service Commission (PSC) approved a new all-services overlay area code: 465.

The new 465 area code will cover the same geographic region as 718, 347, and 929: The Bronx, Brooklyn, Queens, Staten Island, and the Marble Hill section of Manhattan. The earliest activation date for new phone numbers using the 465 NPA is scheduled for June 18, 2026. This ensures that the city has a fresh supply of numbers that is projected to last for approximately 11 years.

The Area Codes of Upstate and Long Island New York

Outside of the five boroughs, New York State is divided into several geographic numbering regions, many of which have also implemented overlay codes in recent years to keep up with population growth and number depletion.

Western New York (Buffalo, Rochester, Finger Lakes)

• 716: The historic area code for Western New York, including Buffalo, Niagara Falls, and the surrounding Erie and Niagara counties.
• 624: The newest overlay code in Western New York, approved in October 2022 and taking effect to serve the same region as 716.
• 585: The area code for the Rochester metropolitan area and the Genesee Valley region. This code was created in a 2001 split from the 716 area code.

Central New York (Syracuse, Utica, Watertown)

• 315: The main area code for Central New York, covering Syracuse, Utica, Rome, Watertown, and the surrounding areas.
• 680: The overlay code for the 315 region, introduced to supplement the depleted numbers in this large geographic area.

Capital Region and Northeast New York

• 518: The original area code for the Capital Region, including Albany, Schenectady, and Troy, extending north into the Adirondacks and to the Canadian border.
• 838: The overlay code for the 518 region, implemented to ensure a continued supply of phone numbers in the Capital District and surrounding areas.

Mid-Hudson Valley and Southern Tier

• 845: The area code for the Mid-Hudson Valley, including Poughkeepsie, Newburgh, and Rockland, Orange, and Ulster counties, created in a 2000 split from 914.
• 329: The newest overlay code for the 845 region, which was introduced in 2023 to meet the increasing demand for phone numbers in the Hudson Valley.
• 607: The area code for the Southern Tier, covering Binghamton, Elmira, Ithaca, and the surrounding counties near the Pennsylvania border.

Long Island and Westchester/Lower Hudson

• 516: The area code for Nassau County, the western part of Long Island, directly east of New York City.
• 363: The new overlay code for Nassau County (516), introduced to manage the high demand in this densely populated region of Long Island.
• 631: The area code for Suffolk County, the eastern part of Long Island, including the Hamptons.
• 934: The overlay code for Suffolk County (631), put in place to ensure number availability across the county.
• 914: The area code for Westchester County, located immediately north of New York City.

Why Are There So Many New York Area Code Overlays?

The proliferation of new area codes in New York is a direct result of the exhaustion of available phone numbers. This phenomenon, known as Number Exhaustion, is driven by a few key factors that are especially pronounced in a densely populated area like New York State:

1. The Rise of Mobile Devices: Every mobile phone, tablet, and data line requires its own unique 10-digit number. New York City, in particular, has one of the highest densities of mobile devices per capita in the world, rapidly consuming number blocks in the original 212, 718, and 516 codes.

2. Competitive Local Exchange Carriers (CLECs): The deregulation of the telecommunications industry led to many new phone companies (CLECs) entering the market. Each carrier is allocated blocks of numbers, even if they don't fully use them, which accelerates the depletion of the overall numbering supply in a given area code.

3. The Shift from Splits to Overlays: Historically, when an area code ran out of numbers, the region was "split," creating a new geographic boundary for the new code (e.g., 212 splitting to create 718). Today, the preferred method is the overlay, where a new code is simply added to the existing geographic region. This avoids the disruptive and costly process of forcing existing customers to change their numbers, but it mandates the permanent use of 10-digit dialing (Area Code + 7-digit number) for all local calls.

Navigating the New York 10-Digit Dialing Requirement

The most important takeaway for anyone calling within or to New York is the mandatory use of 10-digit dialing. Because almost all of New York State's major numbering plan areas now have multiple overlay codes, dialing a local seven-digit number without the area code will typically result in a recorded message informing you that the call cannot be completed.

This rule applies to all major metro areas, including:

• New York City (212, 332, 646, 718, 347, 929, 917)
• Long Island (516, 363, 631, 934)
• Buffalo/Western NY (716, 624)
• Syracuse/Central NY (315, 680)
• Albany/Capital Region (518, 838)
• Mid-Hudson Valley (845, 329)

Whether you're calling a historic 212 business line or a brand-new 465 mobile number in 2026, always remember to dial the full 10 digits to ensure your call connects instantly.
