347 Area Code: Brooklyn, Queens & the Bronx

The 347 area code is New York City’s outer boroughs — Brooklyn, Queens, the Bronx, and Staten Island, plus Manhattan’s Marble Hill — in service since October 1, 1999 as the first overlay dedicated to the 718 territory. Millions of ordinary New Yorkers and businesses carry 347 numbers.

Most people searching this code aren’t asking for a map. They’re staring at a missed call and asking one question: is this spam? So this page starts there.

The 347 call on your screen: spam or not?

The area code alone can’t tell you — 347 is one of the most heavily used consumer codes in the country, so both legitimate callers and spoofers use it constantly. What the digits do tell you is that the number was issued for New York City’s outer boroughs. What they don’t tell you is who is actually dialing, because numbers port, VoIP travels, and caller ID can be forged outright.

The screening test that works is behavioral, not numerical:

• Expected context? If you ordered delivery, booked an appointment, or applied for anything in NYC recently, a 347 call is the default shape of the callback.
• Pressure or payment? Any caller demanding gift cards, wire transfers, crypto, or “immediate action” is a scam regardless of what code they display.
• Verifiable? Hang up and call the organization back on the number from its official website. A real caller survives that test; a spoofer never does.

The area code guide covers the underlying rule: a displayed code stopped being evidence of location — or trustworthiness — years ago.

Who actually dials from a 347 number

Legitimate 347 traffic is simply outer-borough New York doing business. The usual suspects behind an unexpected but genuine 347 call:

• Delivery and rideshare — couriers, restaurants, and drivers confirming a drop-off, often from personal cells.
• Medical and dental offices — appointment reminders and callback lines across Brooklyn, Queens, and Bronx practices and hospital systems.
• Small businesses and contractors — the plumber, the landlord’s management office, the school, the shop returning your voicemail.
• People — 347 skews heavily toward mobile lines assigned since 1999, so friends-of-friends, marketplace buyers, and new coworkers often show up as 347.

None of that makes an individual call safe; it makes the code unremarkable. Judge the caller, not the prefix.

When the 347 number looks almost like yours

One pattern deserves its own warning. Neighbor spoofing is when a robocaller forges a caller ID that matches your own area code — and often your first three digits after it — because people answer numbers that look local. If you hold a 347 number, you’re a natural target: an incoming “347-XXX” that mirrors your own line is more suspicious, not less.

The inversion to internalize: a familiar-looking local number is a reason to slow down, never a reason to trust. Legitimate local presence and spoofing look identical on screen; only the callback test separates them.

What area code is 347?

347 is a New York City area code serving the four boroughs outside Manhattan — Brooklyn, Queens, the Bronx, and Staten Island — plus Marble Hill, the slice of Manhattan north of the Harlem River. It shares that exact territory with 718 and 929, with citywide 917 layered over all five boroughs. All local calls dial at least ten digits (1+ten from most landlines), and a call between any of these codes is a local call.

How the outer boroughs ended up with four codes

347’s story is NYC’s number-demand story:

• 1984 — 718 splits from 212, taking Brooklyn, Queens, and Staten Island (the Bronx followed in July 1992, with 212 dialing permitted there until May 1993). Manhattan keeps 212.
• 1992 — 917 arrives as the numbering plan’s first overlay, spanning all five boroughs.
• 1999 — 347 enters service on October 1 as the first overlay stacked directly on 718, approved in December 1998 when 718’s pool headed for exhaustion. Ten-digit dialing became mandatory in the territory by April 2000.
• 2011 — 929 joins on April 16 as the second 718-territory overlay.
• 2026 — 465 entered service June 18, the newest layer, projected to supply the boroughs for roughly another decade.

Nothing about a 347 number is newer or lesser than a 718 one anymore — after a quarter century, 347 is the sound of outer-borough New York. Manhattan runs its own parallel stack: 212, 646, 332, and shared 917.

Holding a 347 number without a Brooklyn address

A 347 (or 718/929) number is a local-presence asset: outer-borough customers recognize it as one of their own, which measurably helps answer rates for local presence calling done legitimately — real numbers you own, answered when called back, not spoofed digits. Businesses anywhere can hold NYC numbers, provisioned by rate center rather than street address.

SIPNEX sources local DID numbers across NYC rate centers and every other US market, routes them into any phone system, and signs outbound calls at A-level STIR/SHAKEN attestation — so your legitimate NYC-facing calls carry authentication no spoofed display can borrow.
