Area code 212 is one of the 86 original North American area codes assigned in 1947. It first covered all five New York City boroughs. Since 1992 it has served Manhattan only, with one exception: Marble Hill.
Quick answer
- 212 is Manhattan's original area code, assigned in 1947.
- It covers Manhattan except Marble Hill, which uses 718.
- Overlays 917, 646, and 332 also cover Manhattan.
- The new 465 code serves the outer boroughs and Marble Hill, not Manhattan.

| Newest NYC code | 465, outer boroughs and Marble Hill |
How 212 became Manhattan's code
- 1947: 212 is one of the original area codes. It covers all five boroughs.
- 1984: A geographic split for number-exhaustion relief creates 718 for Brooklyn, Queens, and Staten Island. Manhattan and the Bronx keep 212.
- 1992: The Bronx moves to 718, leaving 212 as the Manhattan code. In the same year, 917 is overlaid on the whole city. It was first used only for mobile service.
- 1997: 646 is created as a Manhattan overlay, as 212 approaches exhaustion.
- 2015: The Commission approves a third overlay for Manhattan, covering the 212/646/917 region (Case 15-C-0168).
- June 18, 2026: 465 is activated as an overlay for the outer boroughs and the Marble Hill section. It is not a Manhattan code.
Where area code 212 is and is not used
212 covers Manhattan, with one exception. Marble Hill is a section of Manhattan on the mainland. It is in the 718 region, not 212.
Permissive dialing: what it means
A permissive dialing period gives consumers time to adjust to a change from 7-digit to 10-digit dialing, or to the area code changes that follow a split. The New York Public Service Commission describes it this way in its 2015 order (Case 15-C-0168).
- The 2015 Manhattan overlay did not need a permissive period, because 1+10-digit dialing was already in place for all calls.
For businesses, a dialing change means updating equipment and materials. The order lists reprogramming PBXs, cellular phones, speed-dial lists, and automatic dialers, updating directory listings, changing advertising, and notifying customers.
Neighboring area codes in New York City
212 is one of several codes in the city. The table shows which code covers which part of the city, so you can tell at a glance whether a number belongs to Manhattan.
| Code | Where it applies | Relation to 212 |
|---|---|---|
| 212 | Manhattan, except Marble Hill | Original code for the territory |
| 917 | Whole city | Overlay on Manhattan and every other borough |
| 646 | Manhattan | Overlay on 212 since 1997 |
| 332 | Manhattan | Manhattan overlay approved in 2015 |
| 718 | Brooklyn, Queens, Staten Island, the Bronx, and Marble Hill | Created in 1984 when 212 was split |
| 347 and 929 | Outside Manhattan | Part of the region the 465 overlay joins |
| 465 | The 347, 718, 917, and 929 region, including Marble Hill | Overlay activated June 18, 2026; not Manhattan |
Overlay codes that share 212’s territory
An overlay adds a new area code to the same geographic area, so existing numbers do not change. Three codes now share Manhattan with 212:
- 917 (1992): overlaid on the whole city, not only Manhattan.
- 646 (1997): a Manhattan overlay, created when 212 was approaching exhaustion.
- 332 (approved 2015): the third Manhattan overlay, approved in Case 15-C-0168.
Because the codes overlap, two neighbors on the same block can have different area codes. The area code does not show which building or floor a number belongs to.
| Code | Added | Where it applies |
|---|---|---|
| 212 | 1947 | Manhattan, except Marble Hill |
| 917 | 1992 | Whole city (first used for mobile service only) |
| 646 | 1997 | Manhattan overlay |
| 332 | 2015 (approved) | Manhattan overlay |
| 465 | 2026 | Outer boroughs and Marble Hill, not Manhattan |
The new 465 code: what it means for 212
Area code 465 was switched on June 18, 2026, as an overlay for the 347, 718, 917, and 929 region. That region covers the Bronx, Brooklyn, Queens, Staten Island, and the Marble Hill section of Manhattan.
465 is not a Manhattan code. Manhattan numbers stay with 212, 646, 332, and 917. The New York State Department of Public Service also says new 465 numbers could begin to be assigned in the third quarter of 2027, once the existing numbers in the region run out.
Calls within the 347, 718, 917, 929, and 465 region must be dialed with all 10 digits. If you have an auto-dialer or phone system that dials 7 digits for local calls, check it before you go live with 465.
How to dial a 212 number
A 212 number has ten digits: the three-digit area code followed by a seven-digit local number. New York City calls use 10-digit dialing. A call to a number outside the area code adds 1 before the 10 digits.
Why 212 numbers are in short supply
212 is Manhattan's original code, and numbering supply has been constrained. In its 2015 petition, NANPA forecast that the 212/646/917 complex would likely run out of central office codes in the fourth quarter of 2017. That forecast led the Commission to approve a new Manhattan overlay in 2015.
Using a 212 number for business
Manhattan has four codes that matter for routing. 212 covers most of the island, 646 and 332 are Manhattan overlays, and 917 covers the whole city. A business may hold numbers from several of them, so route calls by team rather than by code.
Marble Hill is the exception. It is a section of Manhattan on the mainland, in the 718 region. The 465 overlay covers it too, but new 465 numbers could begin to be assigned in the third quarter of 2027. If you serve both Manhattan and Marble Hill customers, check which code each address has.
Important: Confirm availability with your provider before you plan a campaign or print a number on materials.
Before you use a 212 number
- Confirm the number is available from your provider, and get its terms in writing.
- Ask who owns the number and whether it can be moved to another provider if you switch.
- Route 212, 646, 332, and 917 calls to the same team when they serve the same customers.
- Set 10-digit dialing for calls to the 347, 718, 917, 929, and 465 region before you go live.
- If you serve Marble Hill, check the 718 numbers at those addresses, and note that new 465 numbers could begin in the third quarter of 2027.
- Plan for caller ID. A local number does not prove who is calling, and caller ID can be faked.
Frequently asked questions
Which area is the 212 area code for?
Area code 212 serves Manhattan, New York City. Marble Hill, a section of Manhattan on the mainland, is in the 718 region instead.
Is area code 212 being split or replaced?
No. Area code 212 is still in use for Manhattan. New overlays were added around it: 917 (1992, citywide), 646 (1997, Manhattan), and 332 (Manhattan, approved 2015). The newest code, 465, covers the outer boroughs and Marble Hill, not Manhattan, and new 465 numbers could begin to be assigned in the third quarter of 2027.
Does a 212 number mean the caller is in Manhattan?
Not always. An area code shows where a number was assigned, not where the caller is now. Scammers also fake caller ID to seem local or trusted, so a local-looking number is not proof of who is calling.
Can a business get a 212 number?
Carriers assign numbers from the area code on a carrier-neutral, first come, first served basis. Whether a specific 212 number is available depends on the provider and the inventory at the time you ask, so confirm availability before planning around one.
