347 Area Code: New York City Location and Time Zone

Introduction

The 347 area code is a New York City code. It covers the Bronx, Brooklyn, Queens and Staten Island, along with Marble Hill, a small neighborhood that is legally part of Manhattan. 347 has no territory of its own: it is an overlay that shares those boroughs with 718, 929 and 465, while 917 overlays the entire city.

If an unfamiliar 347 number just called, you now know roughly where it was assigned. This guide covers the boroughs and counties behind the code, its time zone and overlays, the country code question, how to check and dial a 347 number, and how a business can get one.

Where Is the 347 Area Code?

Area code 347 is used only in New York City: the Bronx, Brooklyn, Queens and Staten Island, plus Marble Hill. So if you are looking up the area code 347 location in the USA, the state is New York and the city is New York City.

Manhattan works differently. Apart from Marble Hill, it uses 212, 646 and 332, and area code 917 overlays both parts of the city. A 917 number could therefore come from any of the five boroughs, while a 347 number points to the outer four or to Marble Hill. The rest of the state relies on other codes, listed on our New York area codes page.

Cities and Counties in the 347 Area Code

Only one city uses 347, but the code spans four counties, because each New York City borough is coextensive with a county of New York State. Since the same codes are shared across all of them, a 347 number can't tell you which borough it came from. The rest of Manhattan is included below for comparison.

Marble Hill is the surprising row. Under the Greater New York Charter of 1897 it belongs to Manhattan, but the Harlem River Ship Canal, built in 1895, cut it off from Manhattan Island, and landfill in Spuyten Duyvil Creek later joined it to the Bronx. When the Bronx moved to 718 in 1992, Marble Hill residents fought to keep 212 and lost, because the neighborhood's wire center is in the Bronx and New York Telephone considered rerouting its trunks too expensive.

347 Area Code Time Zone (Eastern Time)

Every 347 number is on Eastern Time, the zone New York State uses. Clocks move forward on the second Sunday in March and back on the first Sunday in November.

Eastern Time is one hour ahead of Central Time, so noon in Queens is 11 a.m. in the Central zone. If your team works elsewhere, set a 347 line's business hours to New York time.

347 Is an Overlay: 718, 929, 917 and 465

New York City had a single area code, 212, from the 1947 numbering plan until September 1, 1984, when 718 took over Brooklyn, Queens and Staten Island. The Bronx and Marble Hill followed on July 1, 1992.

347 came as an overlay rather than another split. Approved in December 1998, it went into service on October 1, 1999: existing 718 numbers kept their code, new numbers could come from 347, and ten-digit dialing across the 718/347 area was required by April 15, 2000. The New York Public Service Commission approved a further overlay in December 2009, and 929 went into service on April 16, 2011 (see our 929 area code guide).

Area code 917, introduced on February 4, 1992, as the first overlay in the North American Numbering Plan, spans all five boroughs (see our 917 area code guide). The newest code, 465, went into service on June 18, 2026, as New York State's first area code starting with a 4. The Public Service Commission says current numbers keep their area codes and new customers could receive 465 once the region's existing numbers are used up, a point projected in September 2025 for the third quarter of 2027.

Is a 347 number a cell phone? It might be, or it might be a landline. The FCC ruled that area codes can't be restricted to particular types of service (917 received an exemption), and since November 2003 landline numbers have been portable to mobile phones, so the code alone can't tell you what kind of line is calling.

Is 347 a Country Code? What That Search Really Means

No. 347 is an area code, and no country uses it as a calling code. US numbers fall under country code +1, shared by the twenty countries of the North American Numbering Plan, including Canada and a number of Caribbean nations. After the 1 come a three-digit area code, a three-digit central office code and a four-digit line number.

Written internationally, a number from this area starts with +1 347, where the + stands for the caller's international access code. Inside the US, that leading 1 is the long-distance prefix, which is why people search for "area code 1 347."

A number that starts with + and anything other than 1 isn't a US number. Country codes beginning with 3 belong mostly to European countries; Spain's, for instance, is +34. Our United States country code page has more on +1.

How to Tell If a Call From 347 Is Legitimate

A 347 number doesn't make a call risky or safe. The FTC warns that scammers can make any name or number show up on caller ID, so pay attention to what the caller wants. Warning signs the FTC highlights include:

• Pressure to decide or pay right away; honest businesses give you time to think.
• Payment by wire transfer, gift card, cryptocurrency or a payment app, which makes money hard to recover.
• A prize, refund or reward that costs money to collect.
• Someone posing as law enforcement or a federal agency who threatens arrest, fines or deportation.
• A request for the verification code a bank or app just sent you. The FTC says anyone who asks for it is a scammer.

When a call feels wrong, hang up, and on a robocall don't press a key to reach an operator or leave the list. Block the number in your phone's settings, ask your carrier about call-blocking or call-labeling services, or install a call-blocking app.

Report scams, especially if you lost money, at ReportFraud.ftc.gov. Unwanted sales calls can be reported at DoNotCall.gov, where you can also join the National Do Not Call Registry; the FTC notes the registry stops legitimate sales calls but won't stop scammers.

How to Dial a 347 Phone Number

Local calls in the 347 area have required all ten digits since 2000, a rule the Public Service Commission restated when 465 was activated. How you dial depends on where you are:

• Within the Bronx, Brooklyn, Queens, Staten Island or Marble Hill: dial 347 and the seven-digit number. The same goes for 718, 917, 929 and 465 numbers.
• From another US area code: dial 1, then 347 and the seven-digit number.
• From outside North America: dial your international access code, then 1, 347 and the number. Most countries use 00 as that code.

Skipping a digit has caused mix-ups here before. In the year after 347 was introduced, callers who left off the leading 1 when dialing the new code sometimes reached 718 numbers whose next three digits happened to be 347.

How to Get a 347 Phone Number for Your Business

A 347 number gives outer-borough customers a local number to call, and on a cloud phone system it doesn't have to ring on a desk in New York. Because 718 and 929 cover the same boroughs, either is a sound fallback if no 347 number is available.

1. 1Search Ringflow's New York local numbers for a 347 number, or pick 718 or 929 for the same boroughs.
2. 2Forward calls to the Ringflow mobile and desktop apps so the number rings wherever your team is working.
3. 3Set up an auto attendant to greet callers and send them to the right person or department.
4. 4Turn on business texting, and port any existing number you want to keep rather than replacing it.

Already have a 718, 347 or 929 number with another provider? Port it so customers keep dialing the number they know, and add a toll-free number if you also sell outside New York.

Conclusion

The 347 area code belongs to New York City's four outer boroughs and Marble Hill. It has shared that ground with 718 since 1999, 929 since 2011 and 465 since June 2026, with 917 across all five boroughs, and every one of those numbers runs on Eastern Time with ten-digit local dialing.

When a 347 number calls, treat the code as a hint about where the number was issued and let the caller's requests decide how far to trust it. For a local presence in the Bronx, Brooklyn, Queens or Staten Island, Ringflow provides local numbers in US area codes, with a free trial and number porting.
