Area code 917 — All five boroughs, New York City
The first overlay in the history of the North American Numbering Plan. Faced with splitting New York a second time in under a decade, regulators tried something nobody had done before — laying a new code across territory that already had one. It worked, and every overlay since, anywhere in North America, follows the pattern set here.
New numbers available in 917Area code 917 covers all five boroughs of New York City, which makes it the odd one out: every other New York code is either Manhattan or the outer boroughs, and 917 is both.
It was introduced in 1992 for mobile phones and pagers, and that association has stuck long after the technical restriction went away.

How 917 came about
Not a story about running out of numbers so much as about inventing the fix everyone now uses.
- 1984The split that made splits unpopularBrooklyn, Queens and Staten Island are moved from 212 to 718. Everyone affected has to change their number, reprint their stationery and tell their customers. The resentment lasts years.
- February 1992A code with no territory of its ownRather than split the city again, regulators lay 917 across all five boroughs at once, sharing ground with the codes already there. No existing subscriber changes anything. It is the first overlay in the numbering plan’s history.
- 1992 onwardPointed at mobiles and pagersThe new code is directed at the growing mobile and pager market rather than landlines — which is why 917 still reads as a cell number to New Yorkers three decades later.
- 1999 onwardThe pattern spreadsManhattan gets 646 and the outer boroughs get 347, both as overlays rather than splits. From here the technique becomes the standard answer to exhaustion across North America.
Which code should you choose?
917 is the only New York code that does not tell anyone which part of the city you are in.
| Code | Covers | What it signals |
|---|---|---|
| 917 | All five boroughs | New York City, no borough. Historically mobile |
| 212 | Manhattan | The island, and a line opened before 2010 |
| 646 | Manhattan | The island, obtainable today |
| 718 | Outer boroughs | Brooklyn, Queens, the Bronx, Staten Island |
Take 917 if you want to read as New York rather than as a specific borough — useful for a business that serves the whole city and does not want to sound like it sits in one corner of it.
What people get wrong about 917
Is 917 used for spam calls?
917 is spoofed heavily, and its citywide reach makes it a flexible disguise — it can plausibly stand in for a caller anywhere in New York rather than one specific borough. Its lingering mobile association helps the fraudster too, since a call from a mobile reads as a person rather than an institution. Caller ID is a display field, not proof of origin. A 917 number establishes nothing about where a call came from or what kind of line placed it, so treat unexpected requests for payment or personal details as suspect and call back on a number you looked up yourself.
Area code 917 FAQ
What area code is 917?
917 covers all five boroughs of New York City — Manhattan, Brooklyn, Queens, the Bronx and Staten Island. It is the only New York City code that spans the entire city.
Is 917 a cell phone area code?
Not any more. It was introduced in 1992 aimed at mobiles and pagers and the association has stuck, but the restriction is long gone. A 917 number can be a mobile, a landline or a VoIP line.
Why was 917 created?
To avoid splitting New York a second time. The 1984 split had forced three boroughs to change their numbers and was deeply unpopular, so in 1992 regulators laid 917 over the whole city instead — the first overlay ever attempted.
What is an overlay area code?
A second code covering the same ground as an existing one, added when numbers run short. Nobody has to change their existing number; only new lines receive the new code. The trade-off is that local calls then need ten digits.
Is 917 Manhattan or Brooklyn?
Both, and the other three boroughs too. Unlike 212 or 718, a 917 number cannot tell you which part of the city its holder is in.
Can I still get a 917 number?
Yes. 917 is still issuing numbers across all five boroughs, and it is the option to consider if you want a New York number that is not tied to one borough.
What time zone is the 917 area code in?
Eastern across all five boroughs: UTC−5 in winter, UTC−4 in summer.
Is 917 a Manhattan number?
Partly. 917 covers all five boroughs, so a 917 holder may be in Manhattan, Brooklyn, Queens, the Bronx or Staten Island. It is the only New York City code that does not identify a borough.
How do I get a 917 number?
917 is still issuing numbers across the whole city. It is the option to consider if you want a New York number that is not tied to one borough — useful for a business serving the entire city.
Why do 917 numbers look like mobiles?
Because they were. 917 launched in 1992 aimed at mobile phones and pagers, and the association outlived the restriction by decades. A 917 today can equally be a landline or a VoIP line.
Getting a 917 business number
917 numbers are still being issued, so a business anywhere can hold one and route it to wherever its team actually works — you do not need an address in New York.
