City population is shown in full. The share of each city inside 551 is measured from Census tract centroids, not estimated from a rate-center match – so a city split between two codes appears on both, at the fraction each one actually holds. The “% of listed-city population” column uses the full populations of the cities listed here.

What counties does area code 551 cover?

1,592,084 residents across 2 counties, counted inside the 551 boundary — a county split between codes contributes only its part.

Frequently Asked Questions about the 551 Area Code

Who called me from a 551 number?

A 551 number is assigned to Jersey City, New Jersey, so a call may come from there. But caller ID is easy to fake, and scammers often spoof a local 551 code to look nearby, so a 551 number doesn't prove the caller is local. Recently, 966 unwanted-call complaints were reported to the FTC for numbers showing the 551 code (64% flagged as robocalls). If you don't recognize the number, let it go to voicemail; a real caller will leave a message.

Is 551 a scam area code?

No area code is a scam on its own. 551 is a normal, officially assigned code for Jersey City, New Jersey. Spam callers spoof local codes to raise the odds you answer, so 551 on your caller ID says nothing about who is really calling. Recently, 966 unwanted-call complaints were reported to the FTC for numbers showing the 551 code (64% flagged as robocalls). Judge the call itself, not the area code.

Why do I keep getting calls from the 551 area code?

Repeated calls from different 551 numbers are usually spoofing: a robocaller rotates through 551 numbers so each call looks local and slips past simple blocks. Recently, 966 unwanted-call complaints were reported to the FTC for numbers showing the 551 code (64% flagged as robocalls). Blocking one number rarely helps; voicemail screening, your carrier spam filter, and the Do Not Call Registry work better.

Should I answer an unknown 551 number?

If you aren't expecting a 551 call, let it ring to voicemail. Legitimate callers leave a message, most robocallers hang up when no one picks up, and answering can mark your number as active and bring more calls.

How do I block calls from the 551 area code?

Block a single 551 number from your recent-calls list (iPhone: tap the number, then Block this Caller; Android: tap the number, then Block or report spam). To cut the volume, turn on Silence Unknown Callers on iPhone or spam protection on Android, enable spam filtering from your carrier, and register at DoNotCall.gov. Blocking the entire 551 code also stops legitimate local calls, so use it only as a last resort.

Where is area code 551?

Area code 551 covers Jersey City and the surrounding area in New Jersey, spanning 68 cities with about 1,592,084 residents. It shares its area with overlay code 201.

When did area code 551 go into service?

Area code 551 went into service on December 29, 2001. It was added as an overlay of 201, so 551 numbers serve the same area that 201 already covered.

Is 551 a real area code?

Yes. 551 is an active code in the North American Numbering Plan, assigned by NANPA and in service for Jersey City, New Jersey. A real code can still show up on spoofed spam calls, so treat unknown 551 calls with normal caution.

What timezone is the 551 area code in?

The 551 area code is in the Eastern Time (ET). Because a number can be kept when someone moves or switches to VoIP, a specific 551 caller may not be in that zone.

How do I call a 551 number from abroad?

From outside the US, dial your country's exit code, then 1 (the US country code), then 551 and the seven-digit number. From a mobile phone you can usually just enter +1 551 followed by the number and let the phone add the exit code for you.
