347 Area Code: A Complete Guide to NYC's Outer Boroughs

The 347 area code serves New York City's "outer boroughs": the Bronx, Brooklyn, Queens, and Staten Island. It also reaches Marble Hill, a small slice of Manhattan that is physically attached to the Bronx.

Notably, it does not cover most of Manhattan, which keeps its own codes such as 212 and 646.

Like the rest of the city, the region runs on Eastern Time, observing Eastern Standard Time in winter and Eastern Daylight Time in summer. What makes the 347 area code distinctive is that it is not tied to a fresh geographic region of its own — it shares the very same territory as the 718 code, layered on top of it.

Two neighbors on the same Brooklyn block can hold completely different area codes while living mere feet apart. For any company chasing those neighborhoods, a local 347 phone number signals you belong there from the first ring.

To appreciate the 347 area code, you have to rewind a few decades. For years, all five boroughs shared 212. In 1984, the four outer boroughs were split off into the brand-new 718 code, leaving 212 to Manhattan.

By the late 1990s, the rise of mobile phones, pagers, fax lines, and dial-up modems had drained 718's supply. Rather than split the boroughs yet again and force people to change numbers, regulators introduced the 347 area code as an overlay on October 1, 1999.

An overlay assigns a second code to the exact same area, so existing 718 numbers stayed put while new lines could draw from 347.

Demand kept climbing, and in 2011 a third overlay, 929, joined the same boroughs. Today all three codes coexist, which is why ten-digit dialing is mandatory: you must dial the full area code even for a neighbor next door.

Because it overlays 718 and 929, the 347 area code blankets four enormously diverse boroughs. A 347 phone number could belong to a food truck in Astoria, a startup in DUMBO, or a contractor in the Bronx.

The prefix has become shorthand for authentic, street-level New York rather than the corporate gloss often associated with Manhattan's 212. For many small businesses, that grassroots reputation is a feature worth keeping — it signals they grew up alongside the neighborhoods they serve.

For any company serving New York, a local number is more than a formality. Studies of caller behavior consistently show that people answer and trust calls that look local far more than calls from unfamiliar or out-of-state numbers.

In a city as proud of its neighborhoods as New York, that local signal carries real weight.

A 347 area code number tells customers in Brooklyn or Queens that your business is part of their world, fluent in their market and reachable on their time zone. That perception lifts answer rates, shortens sales cycles, and builds the kind of word-of-mouth that thrives in dense urban communities.

This is where the right platform matters. A provider like Teloz, which has built business communication systems since 2005, lets a company pair a local 347 number with a cloud-based business phone system and an AI-assisted contact center.

A lean team can then field calls from all four boroughs with the responsiveness of a far larger operation, routing each caller intelligently instead of letting the phone ring out.

You do not need a storefront in Brooklyn to claim a 347 number. Virtual and cloud providers can assign one to a business located anywhere and route the calls wherever your team works. The setup is usually fast.

Because everything lives in the cloud, you can answer 347 calls from a desk phone, a laptop, or a mobile app, and add new lines as your NYC presence grows, with no hardware to install. Most providers ask for no long-term contract, so testing a New York presence is low-risk: if calls from Queens and the Bronx start climbing, you simply scale up lines and routing rules instead of rewiring an office.
