Most Common Area Code 640 Scams

The 640 area code is seeing a rise in fake Reader's Digest sweepstakes and Amazon scams. Fraudsters claim you won a lottery or need to verify an order to steal your money.

Reader's Digest Sweepstakes Scam

A caller from the 640 area code claiming to be "Dave Williams" from Reader's Digest calls to tell you that you won the "Megamillions sweepstakes" worth $3.5 million, a 2022 E Class Mercedes, and $5,000 a week for life. He speaks with a heavy accent despite using a common American name. To claim your prize, you must first pay either $25,000 or buy a $500 gift card. They use this payment to steal your money while you receive nothing. Real sweepstakes never require upfront fees to claim prizes.

"Caller said he was Dave Williams... and that I'd won the Reader's Digest Megamillions sweepstakes. This included: $3.5 Million USD, a 2022 E Class Mercedes, $5,000 a week for life... All I needed to provide was $25,000. When I said I didn't have that, he asked if I would buy a $500 gift card and call them back."

Fake Amazon Purchase Scam

A caller pretends to be from Amazon and alerts you to a fraudulent charge on your account for a cellphone costing $599. They provide a fake 5-digit order number to seem legitimate and urge you to call a specific number they provide to authorize or cancel the charge. When you call that number, they steal your personal and financial information during the fake resolution process. Amazon uses much longer order numbers and never calls customers to authorize charges.

"This number is given as a call back number in a message pretending to be from Amazon wanting the recipient to call and authorize a charge for $599 for a certain cellphone. The order number they reference is a 5 digit number which I know from previous Amazon orders is in no way even close to a valid Amazon order number."

Employment Verification Phishing

A caller claims they need to verify someone's employment but refuses to provide the name of the person they are asking about. Instead, they quickly pivot to asking for a contact email address, making the call feel vague and unprofessional. They use any email addresses you provide to launch targeted phishing attacks against your company. Real employment verification requires the caller to identify the specific employee and provide their own company credentials.

"asking to verify employment of someone without giving the person they wanted to verify and instantly just asked for an email. Phishing."

Is area code 640 a scam?

No, 640 is a legitimate New Jersey area code serving the same South Jersey territory as 609, including Trenton and Atlantic City, added as an overlay in 2018. Because it shares geography with its parent code, it carries the same local credibility for anyone targeting that region.
