The 551 area code is dangerous due to the "grandson in jail" emergency scam and IRS lawsuit threats. These criminals prey on your family loyalty or fear of the government to trick you into sending cash quickly.
"This number called my husband's grandmother claiming to be David Bell a public defender. Saying that my husband had been in a crash and was intoxicated and that she needed to send $3500 to bail him out. He even had her believing she was talking to my husband."
"Continous threating phone calls that I have been named in a lawsuit. That they are government officials that will contact local county officials to follow suit. Pretending to be police officers to get personal information. IRS was the organization that was named to be filing the suit."
"Yes, got email stating I had 4 hours to call the number 551-210--8174 to cancel or dispute an order of $449 for annual subscription for Norton computer security. I made no order and will not call the number."
"I got a call from this number claiming to be from the Transworld System Inc. who advised that i have a debt with MTA for unpaid tolls of $2,190. I advised them that it was impossible because i have E-Zpass and i pay automatically from my account."
"He knew how much I owed and I tried to get a settlement number. He was SUPER aggressive. He wanted to know if I was going to pay with a debit card or a bank account number. I said I wanted to hear what his supervisor said. He said I needed to give him those numbers first. Big Red Flag!"
"Threatens to sue you if you don't provide your Social Security Number. Apparent Identity Thieves."
Area code 551 covers the northeastern portion of New Jersey.
Area code 551 is an overlay for area code 201 . Area code 201 was established in 1947, and area code 551 was added in 2001. Ten-digit dialing is mandatory in this region.
No, 551 is a legitimate New Jersey area code serving Jersey City, Union City, and Bayonne, overlapping with 201. Scammers spoof it because local Hudson County numbers feel familiar and trustworthy to northeast residents.
A local New Jersey number is harder to dismiss, which is precisely why fraudsters favor 551 for high-pressure calls. Grandparent bail scams impersonating public defenders, fake IRS arrest threats, and aggressive American Express impersonators demanding debit card numbers are the most reported fraud types from this prefix.
