History of the 646 Area Code

Manhattan used only 212 for most of the 20th century. By the late 1990s there were almost no 212 numbers left. 646 entered service on July 1, 1999 as an overlay for Manhattan.

Demand kept growing, and a third Manhattan code, 332, was added on June 10, 2017. Today a new Manhattan line is far more likely to get 646 or 332 than 212.

How to Dial a 646 Number

Local calls in this area are dialed with the area code included.

• From another country: your exit code + 1 + 646 + the seven-digit number

Is a Call From 646 a Scam?

Most 646 calls are from real Manhattan residents, offices and mobile phones. Because a New York number looks important, scammers spoof 646 for fake bank alerts, fake job offers and investment pitches.

Watch for these warning signs:

• Fake bank or card fraud alerts that ask for your PIN or passcode
• Calls about Medicare, health insurance or a car warranty you never asked about
• Messages that claim a family member is in trouble and needs money
• Pressure to stay on the line and act right now

Caller ID can be spoofed, so the number on your screen does not prove where a call comes from.

What to do with an unknown 646 call

• Hang up as soon as a call feels wrong. You do not owe a stranger an explanation.
• Verify the caller through an official number, not the one they give you.
• Block the number.
• Report scam calls at reportfraud.ftc.gov and register at donotcall.gov.
• Forward spam texts to 7726 (SPAM).

How to Get a 646 Phone Number

You do not have to live in New York City to use a 646 number.
